I am interested in learning more about Manhattan Project Associate Director William S. Parsons, at the time a naval Captain. I've read bits and pieces about him in numerous books, web sites, and even TV documentaries. Is there one book (or more) in particular that singles him out for his role in the project?

Dear Mr. White:
There is an excellent book titled, Target Hiroshima, Deak Parsons and the Creation of the Atomic Bomb, authored by Al Christman (1998, Naval Institute Press, Annapolis, Maryland) which can be purchased from Amazon.com.  If you have not already read it, I strongly recommend it.  Thank you for your interest in the Manhattan Project Web Site.  Sincerely yours, Joseph F Papalia

Great website!
I was interested to note that the Little Boy bomb was the 'first and last weapon of the gun type device.' Does this mean there was no test of the bomb dropped on Hiroshima prior to it's actual use?
There was no test of the uranium gun-type bomb because all of the highly enriched uranium that was produced at Oak Ridge was needed for the Hiroshima bomb. It is interesting to note that more than 45,000 workers at Oak Ridge were working 7 days a week for 18 months and they could only produce enough enriched U-235 for the one bomb.

On the other hand, the bomb that exploded at the Trinity test was a plutonium implosion type bomb...the same as the Nagasaki bomb. At that time, Hanford was producing enough plutonium to produce one bomb per week.
Thanks so much for the explanation. It is hard to believe that such a weapon could have been used w/o any sort of actual test. I suppose the theoretical aspects of this gun barrel bomb were such that the scientists (and the President?) were confident it would work? It just amazes me that the first atom bomb was used w/o testing. It sinks my arguments about the North Korean's supposed nuclear capability . I always have maintained that until a country successfully conducted a test (e.g., India, Pakistan), there was no real reason to fear their weaponry. Interesting...

Hello, I am a student of the closing days of WWII and particularly of the atomic attacks on Hiroshima and Nagasaki.  My question is this:

What tail designation did Bockscar carry during the Nagasaki attack?  I know that the 509th CG's normal tail designation was "Circle Arrow" but that Enola Gay was repainted to "Circle R" for the Hiroshima attack.  I have seen an artist's painting titled "Bockscar Inbound to Nagasaki" and that painting showed a "Circle 89" tail designation.

I have visited Bockscar at WPAFB and I believe it presently carries the "Circle Arrow".Any information would be greatly appreciated. Thank you.

Dear Scott:
Good question.  Bockscar flew to Nagasaki with the tail markings of the 444th Bomb Group which was part of the 58th Bomb Wing based on Tinian.  The other fourteen B-29's which were part of the 509th also took on spurious markings so as not to attract any attention to themselves because of their mission.  The Enola Gay flew with the Circle R which was the 6th Bomb Group, 313th Bomb Wing.  They all later reverted back to the arrow in the circle which was the marking of the 509th Composite Group, 393rd Bomb Squadron.  Thank you for your interest in the Manhattan Project Web Site. Sincerely yours, Joseph Papalia

Why the fissionable material for Little Boy was shipped on the Indianapolis but the same material came by air for Fat Man?

It was felt that it was 'safer' to send the enriched uranium for Little Boy by ship. This enriched uranium, the entire supply that was produced at Oak Ridge, could not have been replaced.  The plutonium that was used in Fat Man, on the other hand, was being produced at Hanford at the equivalent rate of about 1 bomb per week.

 

Q-71

Can you give me any more information about the bronze "A" bomb pins? I found one in my grandmother's jewelry box after her death that most certainly must have belonged to my grandfather. He was a civilian who worked as probably some type of manual laborer/construction worker during that time.
Thank you very much for visiting our web site and for your question. The bronze pin was given to all participants of the Manhattan Project with less than 12 months of service. A silver pin was issued to those with more than 12 months of service.

i want some information that albert einstein is not morally responsible concerning the manhattan project or the bombings that destroy thousands of lives in nagasaki and hiroshima. pls help me. i'll have to defend it for my debate tomorrow.  i really need your answer this time.
Thank you for visiting our web site and for your question. We cannot give you information that Einstein was not morally responsible for the development of the atomic bomb because, as you say, it is open to some debate. There is no question that Einstein's letter to FDR did result in the development of the A bomb being put on the 'front burner' with a new sense of urgency. The A bomb would have been developed anyway, but probably not in time to end the war.

Einstein's motive was based on a confidence that Nazi Germany was building a bomb also and he felt that there could be no greater catastrophe than the Nazi's possessing an atomic weapon. We feel certain that Einstein would have sanctioned some type of use against Germany had Germany been in a position to use a similar weapon themselves.

After the war, Einstein said that had he known at the time (1939) that Germany was not working on an atomic bomb, "he would have not lifted a finger to help."

Hi Joseph
I am currently enjoying your collection of pictures regarding the dropping of the atomic bomb. Are there any surviving members of the flight crew of the Enola Gay alive today ?
 
Thank you so much
Dan Owen
Dear Dan:
Thank you for your nice comments concerning my collection.  There are three remaining members alive today.   Paul Tibbets, Pilot, Ted "Dutch" Van Kirk, Navigator and Morris Jeppson, Weaponeer.  Tibbets has his own website, theenolagay.com, Jeppson lives in Las Vegas and Van Kirk I believe is in California.  Thank for your interest in the Manhattan Project Website.

Comments:
Why did we drop the bomb on Japan and not Germany? Japan was almost defeated and most likely would have surrendered soon.
Thank you for visiting our web site and for your very good question. The bomb was not tested until July 16, 1945, more than 3 months after the surrender of Nazi Germany.

As to whether Japan was ready to surrender any time soon is open to debate. In August of 1945, more than 1,000 American and British POW's were dying each week due to mistreatment at the hands of Japanese captors. The experiences gained in Iwo Jima gave most Americans the feeling that Japan would not surrender easily.

I really enjoyed browsing your sited and found a better understanding of what truly happened during WWII. However, I always wondered who came up with the name "Enola Gay". It's such an unusual name and I am hopeful that you give me some info on this. Thank you very much.
"Enola Gay" Tibbets was the name of Col. Paul Tibbets' mother.  Col. Paul Tibbets was the pilot of the Enola Gay.

 

Q-64
10/25/03
I believe that the names of the Enola Gay crew are Stenciled (not signed as I had indicated in last email) on the right side of the forward fuselage. The Navy CAPT (Parsons) who I believe armed the weapon in flight is not listed on that set of printed names. There may have been one other crew member that also was not listed.  I'm a new docent for the Udvar-Hazy center and I'm curious why the CAPT's name is missing from that stenciled-on set of names. Oversight? Purposeful omission?
 
Thanks!
Paul  
The names which appear on the fuselage of the Enola Gay were the operating crew of that aircraft.  Technically, Capt. Parsons, Weaponeer and  Lt. Morris Jeppson, Bomb Electronics Officer  were not.  They were primarily concerned with arming and monitoring the bomb and thus had nothing to do with its flight.  The pictures which show the crew prior to takeoff do not include them because they did not want to be. However, in later pictures they were photographed posing by the Enola Gay. Capt. Parsons, later known as the "Atomic Admiral," was part of Project Alberta.  He died in 1953 from a heart attack and is buried at Arlington National Cemetery.  Morris Jeppson, an Air Force officer was attached to the 1st Ordinance Squadron which was part of the 509th Composite Group.  I saw  Dick Jeppson at the last  509th reunion (10/03) held in New Orleans.  He is retired and living in the Las Vegas area.  If you are interested in having a scanned picture of Jeppson by the Enola Gay, please let me know.  Good Luck on your position at the Udvar-Hazy Center.  I plan to go there next year.

Question:  Woody Swancutt Aircraft Commander of "Dave's Dream" was with what Bomb Group in 1943-44 and where?
Dear Mr. Corradina:
In answer to your question, Gen. Woodrow Swancutt served as a B-29 pilot in the 40th Bombardment Group, 20th Bomber Command.  The first B-29 unit to see action.  He flew 49 combat missions in the China -Burma-India and Pacific areas.  He flew the first B-29 daylight attack on Japan against the Yawata Steel Mills.  For this outstanding achievement, the unit was awarded the Presidential Unit Citation.  Gen. Swancutt died in 1993.  
The 40th Bombardment Group was stationed at Chakulia Army Air Base,India.  The also flew out of Hsingching, China, China Bay, Ceylon and ended the war stationed at Tinian.
Thank you for your interest in the Manhattan Project web Site. Sincerely yours,  Joseph Papalia

In the gaseous diffusion process; in what form was the uranium at the last barrier?
Uranium hexafluoride (UF6) GAS  throughout the cascade, bottom to top, No deviation, other than increase in isotope enrichment above the feed point, decrease below the feedpoint. Sub-atmospheric pressure, elevated temperature (provided by the pumps moving the gas.  Should have pointed out that the UF6 is removed by freezing the gas in a removal vessel, it then being reduced to UF4, and then thermally reduced with Na or Mg to a metal "button" the size of which is of course limited by critical mass. (answer provided by Lawrence O'Rourke, an engineer at the K-25 plant during WWII)

Question:
Hi, This is a great website. I am in the process of building a 1/72 scale model of the Enola Gay. It would be great if someone could answer a few questions re what the plane looked like on the mission with the atomic bomb. 1) What kind of props did it have and did they have yellow tips? I have 2 sets of props in my kit. One set is wider and has what appears to be 2 sections on each blade. The other set is narrower and looks like a normal prop. 2) What is the small black square above the 2 on 82 on the aft part of the fuselage just below the vertical stabilizer. Is it a window or black paint? It doesn't appear in all photos that I have seen. 3) Did the plane have the R symbol or the arrow symbol on the mission? Thanks for your help. Mike
Dear Mike:
Thank you for your kinds words regarding the website.  To answer your questions: If you will go to Gen. Paul Tibbets' website, theenolagay.com and click on the word plane in the listing, you will get your  specs regarding the props.  Yes they were yellow tipped.  This was to catch the eye when they were spinning so you would not walk into them.  Go to my collection and look at item #30.  The small black square is in fact a window which I am told was to let light in so those crew members in that part of the plane could see.  I have not seen them on all B-29's.  The tail marking during the mission was a circle R (6th Bomb Group).  Tibbets' ordered it put on so as not to bring attention to his aircraft and others by the Japanese. The arrow in the circle was put back shortly after the mission.   If you go to the home page  and click on Legacy of the Enola Gay, scroll down and just below the large red word BEFORE you will see a picture of the Enola Gay  returning from Hiroshima.  Click on it for a better view.     
I hope this has been of some help to you.  Sincerely yours, Joe Papalia

Frank Abato
New YORK
Question:
Where did the name Enola Gay come from?
This is a very common question.  The B-29 superfortress was named for Enola Gay Tibbets, the mother of it's pilot, and the commanding officer of the 509th Composite Group, Col. Paul Tibbets.

 

Q-59  It is my understanding that Monsanto had a downtown Dayton facility that worked with making the initiators for the Manhattan Project.  Mound facility opened after WWII where initiator development continued (not sure when it ended). Mound also designed and built the Pu heat energy source used by the Space program.  Plutonium was stored in building 1A at the Mound facility.  Modern initiators are electronic devices made by the Pinellas Fla plant up until it closed in the 80's.

Thanks for your question.  Following is from a woman physicist at the Bonebrake Facility:  "In December 1943, I was one of about 20 people starting to work at Unit III of Monsanto, under the Manhattan Project.  Our work place was the former Bonebrake Seminary, at 1st and Euclid Streets in Dayton.  The building was in the process of being renovated.  There was no central heating, no air conditioning, and no stairs to the third floor.  We nearly froze the first winter, with only one small electric heater for our large lab.  In summer, the heat was stifling.  Our windows were sealed shut, I presume for security reasons.  The people I remember who were there that first winter, were Dr. James Lum (laboratory director) and Evelyn Sands, his secretary, and Dr. Malcolm Haring, later plant manager at Mound."   Please click on link below for the rest of the story!

Comments:
I am looking for biographical information about a scientist named Viscardi who worked with Fermi on the Manhattan Project. Our interest lies in the fact that in 1964 he donated his 1000 strong scientific book library to Malta. It has always been a mystery why he did so. Perhaps if we know some more about his early life we could solve this riddle.
If anyone has an answer for this, please contact Mr. Boffa directly.

Hello,
I would really like to know the answer to the following:
When the war was over, there were apparently over 60 "Pumpkins" left on Tinian. These were the bombs that looked and felt like the Fat Man, used for target practice. Apparently these "Pumpkins" were thrown into the sea after the war.
Question:
1) Where were they disposed of (exact or at least general location near Tinian -- to the south of the island, etc.)
2) Who, or what organization, was in charge of the disposal? And would there be any paperwork that reported of such disposal?
In answer to your question, I was informed by retired Vice Admiral Frederick Ashworth (Weaponer on Bockscar) that during  the early part of September, 1945, he and Colonel Kirkpatrick  (Corps of Engineers) were directed by General Groves to dispose of the remaining pumpkins and other components which were of insufficient value to justify shipping back home.  This material was laid out on a runway and crushed by a bulldozer.  They were then taken by truck to Tinian Port to be shipped out to sea.  Tinian Port is on the south side of  the island.  This was the only way that ships came into Tinian (as did the USS Indianapolis) due to the rugged coastline which made it impossible for large shipping to dock any where else.  The assumption is that they were taken south for disposal.  Admiral Ashworth is not aware of any specific written order to do this, but believes it was rather word of mouth.  Much of the electronic equipment which was used in conjunction  with the bombs was shipped back to Los Alamos.  Admiral Ashworth then returned stateside on September 10th after turning all buildings used with the bomb project over to the island commander. Sincerely, Joe Papalia jpap@worldnet.att.net

I read recently that the uranium supplied for Little Boy was supplied by Canada. Could you verify this and if you can, tell me how I could find out more. Thank you.
The earliest uranium (1,200 tons of ore or "pitchblend") was received secretly from the Belgian Congo in Africa. Soon thereafter, Stone & Webster of Boston contracted for Canada's supply of uranium. It was mined at Great Bear Lake, beyond the Arctic Circle in Northern Canada beginning in 1942-43.

We are attempting to trace the routing of this uranium ore from Canada. We believe it was secretly shipped to the Seneca Army Depot near Seneca Lake in the Finger Lakes region of upstate New York. It is believed that it was then sent to Mallinckrodt Chemical in St. Louis for purification (not to be confused with enrichment) and then on to Oak Ridge.

What was the location of the New York Headquarters of the Manhattan Project?
The headquarters of the MED were at NYC only a short time before relocating to Oak Ridge.  Later, the Nash Building was at the corner of Broadway and 133rd St. The Woolworth Bldg. was on Broadway between Park Place and Barclay St.  These two locations were primarily involved in gaseous diffusion research.  Pupin Hall at Columbia University was the site of the S.A.M. Lab.

Comments:
Where the people told about the risks (like radioactivity) of the atomic bombs ? Did anybody wonder about it ? How did they react ? Were they not worried afterwards about the risks of a test like Trinity ?
Thank you very much for visiting our web site and for your excellent question. We are always glad to hear from visitors from Europe. As you probably know, very few knew what the true purpose of the Project was. Most didn't know. Of this large majority, many were engineers and chemists and figured out the implications of radioactivity once they learned of the materials they were working with. However, most were not informed about the dangers and it was only after the war that the issue became public knowledge. It is interesting to note that most of the danger involved toxic substances that were not radioactive...ie., beryllium, uranium hexa-fluoride gas, lead, etc. The United States Dept. of Labor has acknowledged the role that the Manhattan Project played in the health problems of many of its workers. There is a compensation plan in effect to reimburse veterans and their families for related health problems.

Hello,
I was going through your website when I came across the “Mystery surrounding Michael Merriman” section. It says that John Cusack’s character was loosely based on Lois P Slotin, But I thought that it was Harry K. Daghlian who was the first casualty at Los Alamos while “Tickling the Dragon”. Am I misinformed or just have 2 stories crossed? I am doing a college paper on Los Alamos "Project Y" so any information will help. Thanks, Scott
Thank you for visiting our web site and for your excellent question. The actual movie promos stated that it was based on the Louis Slotin accident. You are right of course that Harry Daghlian was the first to die in such an accident. The movie also 'moved' the accident earlier so that it was shown as occurring prior to the Trinity test. In fact, Harry's accident was in August 1945 after the test.

Comments:
I am familiar with the account of the USS Indianapolis transporting nuclear material to Tinian before it was sunk. I am seeking clarification. Did the USS Indianapolis transport both "Little Boy" and "Fat Man", just the uranium and plutonium, or what? The accounts I have seen talk about the Indianapolis transporting the 1st atomic bomb to Tinian. How did the second one get there?
Dear Mr. Lethcoe:
     In answer to your question,  The USS Indianapolis transported the following parts of the Little Boy bomb:
1.  Projectile assembly of active material for the gun type bomb.
2.  Special tools and scientific instruments.
3.  Inert parts for a complete gun type bomb.
4.  Uranium-235, half  the fissionable amount available in the United States at the time valued at $300 million dollars.  This material was flown from Kirkland Air Force base in Albuquerque, New Mexico, to Hamilton Field, near San Francisco, California, taken to Hunter's Point Naval Shipyard to be loaded on the USS Indianapolis.  On July 26, 1945, a C-54 Transport plane departed Kirkland Air Force Base with the three separate pieces of the Little Boy Target assembly.  Two additional C-54's departed with Fat Man's initiator and plutonium core.  These aircraft were responsible for taking their cargo to Tinian.  Upon their arrival, these components were loaded into the casings of each bomb by scientific crews based on Tinian for delivery to their respective targets.  I would recommend the following books for a better insight into this:

Question: I heard that before the atomic bomb was dropped, Maj. Thomas W. Ferebee (bombardier on the Enola Gay) pasted an actress' photo to the bomb (or somebody did). I haven't been able to find any documentation on it. Is it true - if so, where can I find that in writing? Thank you for your help, Karl Stefanicki

Why don't you dispel rumours about how easy it is to build an atomic bomb or how small they can be made. You might have a briefcase bomb but it would take an Olympic Weightlifter to carry it.
Thank you,
Is it possible that Al-Quaeda has Olympic weightlifters in their ranks?

Wasn't there a bridge in Santa Fe that was a common meeting place for Klaus Fuchs and his handler while Klaus was at Los Alamos? Can anyone tell me where any of their meeting sites were? Thanks.
Klaus Fuchs met his courier, Harry Gold, in June 1945, at the Castillo Street Bridge in Santa Fe. A second meeting on September 19, 1945, was at a church, nearby.

I have read extensively about the Manhattan Project and have become very curious about the death and circumstances relating to William Deke Parsons.
Thank you for your attention to this and I will look forward to a reply.
Dear Mr. Worrell:

I apologize for the delay in answering your e-mail. I was in Atlanta for a week and just came back.

Rear Admiral William S. "Deak" Parsons, also known as the "Atomic Admiral" succumbed to a heart attack in December, 1953. After complaining of chest pains to his wife the night before, he was taken by her the following morning to Bethesda Naval Hospital and while being examined by doctors suffered a massive coronary and died. He was buried at Arlington National Cemetery. The implication was that it may have been brought on by stress over the treatment of Robert Oppenheimer during the McCarthy hysteria of this period.  Joseph Papalia

A visitor asked "What was the street address of the storage facility in Staten Island NY where the 1250 Tons of high grade uranium ore was stored in 1939?" I am a Staten Islander and I am interested to know as well. I have heard that the containers were stored in an area that is now at the base of the Bayonne Bridge. One of three bridges that connects Staten Island to New Jersey. If that is correct the address would be somewhere on "Richmond Terrace" a main drag that runs along the waterfront. I hope this helps and if anyone knows and more information I would greatly appreciate it if you could drop me a line.

Dear Sir or Madam,
I am a teacher in Japan, and am attempting to research issues related to the decision for taking Niigata off of the list of potential targets. Here are some of my questions and thoughts. I would certainly welcome your feedback:
* Are there any transcripts or memos that have been declassified which specifically discuss the decision to take Niigata off the list?
* Niigata was restricted from being bombed until July 20th, when the 6th Bomb Group was sent to mine Niigata Harbor. One of the B-29s, piloted by Captain Gordon Jordan, was shot down and crashed east of Niigata City. Related to this event, I have a few questions:
1. Was this a "Pumpkin Mission" to test out Niigata's defenses and practice a potential atomic bombing run? Since they used mines, and not bombs on this mission, I have my doubts, but I would like to find out if possible.
2. Did the B-29 which was shot down have anything to do with the decision to take Niigata off the list of potential sites for atomic bombing?
Thank you in advance for any help you might be able to provide.
Dear Mr. Hadley:
In response to your question as to why Niigata was removed from the list of potential atomic targets:
On the first mission Hiroshima was designated primary, Kokura secondary and Nagasaki the tertiary target. At this point, Niigata was not eliminated.  The second mission designated only two targets. They were Kokura as primary and Nagasaki as secondary. Because the orders stated a visual drop only (no radar) Kokura was spared due to cloud and smoke cover. Niigata
was not considered as a tertiary target because of its great distance from the other two cities. I'm not aware of any memos or documents that take Niigata off of the list, but this does not mean that none exist. However, there are declassified documents that specifically list Niigata as a choice of target.  The mining of Niigata harbor was part of an ongoing strategy to deny the Japanese much needed supplies to continue to wage war. This was common to all ports of entry which were crucial to this effort. Therefore this was not a pumpkin mission, nor was Captain Jordan's aircraft one of the fifteen B-29's which were specifically configured for the pumpkin drops.  It is not inconceivable to surmise, that had the war continued beyond the surrender date, Niigata may have suffered the same fate as Hiroshima and Nagasaki .for further insight into this matter, I would suggest the book, Now It Can Be Told, by Gen. Leslie Groves (DeCapo Press, Inc.).
Sincerely yours,
Joseph Papalia

Gentlemen, I was thinking the insigna on Bockscar at one time was dice, am I incorrect? I was also thinking that Inola Gay bomb bay doors had been converted to have a hump to carry the larger bomb but Bockscar carried the larger bomb.
Dear Mr. Midkiff
The only change in the configuration of the 15 B-29's assigned for the atomic attacks was that their normal gun turrets (with the exception of the tail position) were not added at the time of their construction. This was to lighten the load of the aircraft. The bomb bays were untouched. Because of the size of each bomb, a pit with a hydraulic lift was constructed and both aircraft were placed over it to load their weapons. After the war, B-29's assigned to the nuclear deterrent had their noses raised by jacks so as the bomb (similar to Fat Man) could be loaded into their bomb bay.
 
The nose art for Bockscar was added after the Nagasaki mission. Prior to that it was known as aircraft #77 (Vector #77) I'm not aware of any nose art with dice for this aircraft prior to that. The name Bockscar was given for its pilot, Capt. Fred Bock whose plane it was. The crew that flew it was from the aircraft Great Artiste, which accompanied Bockscar to Nagasaki.
I thank you for your interest in our website.

Dear Sirs: My 15 year old daughter claims a history teacher told her class the crew of the Enola Gay eventually all died of radiation-type diseases....which I told her I didn't think was the case. Could you please set the record straight on that? Thanks!
Dear Mr. Kilgore:
As a former history teacher, I can assure your daughter that the crew of the Enola Gay did not die from radiation related illnesses.. The first member, Robert Shumard died in 1967, almost twenty two years after the mission. Subsequent to that, other members have passed away, the last being Richard Nelson, Radio Operator on February 1, 2003 at the age of seventy seven. There are three remaining crew members who are still alive today. Paul Tibbets, the pilot (visit his web site Enola Gay), Theodore "Dutch" Van Kirk, navigator and Morris Jeppson, Weaponeer.  Admiral William Parsons, one of the weaponeers on the Enola Gay. He died on December 5, 1953. Admiral Parsons sudden death is believed due to a heart attack. I hope this clarifies some of the misconceptions that have unfortunately been circulated.

Could you make a recommendation re: what you believe is the best, most comprehensive, and ideologically objective book on the Manhattan Project?
Probably, the best and most comprehensive, "ideologically objective" book is "Manhattan Project: the Untold Story of the Making of the Atomic Bomb" by Stephane Groueff, Published March 1967. It is available at Amazon. Of course, Richard Rhodes book "The Making of the Atomic Bomb" is comprehensive but less objective...in my opinion.

I need you to clear up a mystery.

It is generally accepted that Charles Sweeney was the aircraft commander on Bock's Car. However, in the official note awarding members of the Bock's Car crew the DSC, there is no mention of CS.?

Now, the next mystery - according to the account written by William Laurence in his book "Dawn Over Zero", he states (on page 193) ...."The co-pilot of our strike ship is First-Lieutenant Charles D. Albury..." In your picture #88 of the just-returned Nagasaki mission crew, Fred Olivi is listed as co-pilot, as he is in the DSC note. Is Albury in picture #88? Incidentally, I do realise that Laurence believed the Nagasaki strike ship was "The Great Artiste", whereas he was actually in the GA himself (with Frederick Bock as pilot). I can't understand how a respected journalist could not get the facts right!! So maybe he was wrong about Albury being the co-pilot!!

In your picture #86 (The Bock's Car crew), Sweeney, Albury & Olivi are pictured together (two 'pilots' and one 'co-pilot' for one aircraft?).

Another point here - if I am right, Sweeney did not have a B-29 assigned to him, but flew with Crew 15, in #89 (The Great Artiste), usually commanded by Albury, with Olivi as co-pilot, Beahan as the bombardier and van Pelt as the navigator. This was similar to Tibbets flying with a modified crew in #82.

Well, I hope you can figure out what I am trying to ask you!! I would really like to know where Albury fitted into the Nagasaki mission history?

I must congratulate you on an excellent presentation, and for making all these historical items available. Like you, I have been studying the history of the Manhattan Project for 40 years (I am 58), and have the usual collection of books, video tapes etc, but nothing like your superb effort.

Thank you very much for visiting our web site and for your questions.

Here is the answer to the 'mystery'. The B-29's normally carried a crew of 9, 4 officers and 5 enlisted men. For the two atomic missions, there was added a 'mission commander" who in addition to piloting the aircraft since he was a senior officer, also commanded the other 5 B-29's in the Nagasaki strike force. Maj. Charles Sweeney whose regular assignment was Commanding Officer of the 393rd Bombardment Squadron, was chosen as mission commander. When he flew as pilot of Bockscar, everyone else got bumped down...Albury as co-pilot "officially" and Olivi as a "spare" in the jump seat. However, most history books indicate that Albury was the pilot (because that was his normal position) and Olivi as co-pilot for the same reason.

The same thing happened on the Hiroshima mission as Paul Tibbets was the mission commander. Also, for the both atomic missions, there were three additional crew members on the Enola Gay and Bockscar...two 'weaponeers' and 1 radar counter-measures officer.

Hi there,
(I'm resending this message with my corrected email address) A page on the DOE website said that uranium was stored at Tyson Valley Powder Farm near St. Louis from 1942 to 1949. Does anyone know what type of uranium this was, where the uranium came from, why it was stored there, and where it was shipped to? Any info/insights would be greatly appreciated. Thanks
Thank you for visiting our web site and for your question. We will have to do some digging but we can answer some of the questions. Mallinckrodt Chemical in St. Louis processed most of the uranium utilized in the Manhattan Project. The uranium was stored at Tyson Valley. This uranium was pure uranium processed from uranium oxide ore. It was 99.3% U-238 and .7% U-235. This uranium was shipped by rail to Hanford, Washington where it was made into "slugs", encased in aluminum cans, and inserted as feed material for the giant reactors at Hanford.

WHY WAS THE MANHATTAN PROJECT CALLED THE MANHATTAN PROJECT AND NOT SOMETHING ELSE?
The name 'Manhattan Project' first came into use because the atomic bomb project was first organized under the direction of the Manhattan Engineer District of the U. S, Army Corps of Engineers in New York City.  Later, as the Project expanded, and its headquarters were transferred to Oak Ridge, TN, the name 'Manhattan Project' was kept as a subterfuge.

Do anyone know if these companies in Buffalo, New York were sub-contractors for the Atomic Energy Commission or Manhattan Project in the 1940's? Buffalo Arms Corporation, Niagara Tool and Machine, National Aniline aka I. G Farben Co. They might have been sub-contractors for known companies already identified as nuclear weapons producers in the Buffalo area, such as Allied Chemical or Linde Air Products. I need proof that they (or one of them) were government sub-contractors producing nuclear weapons or components during this period. Thanks

My question is about test site selection. In the book The Making of the Atomic Bomb, several areas are mentioned including southern California. Do you have any information about where? It sounds like it might be camp Young, desert training camp.

Thank you for visiting our web site and for your very good question. From a veteran who was involved in the site selection we have learned that there was one site considered in southern New Mexico and one site in California along the western side of the Colorado River near Blythe, California.

 

With great interest, I looked at the montage photographs of the aircraft involved in the Hiroshima and Nagasaki missions. I had been under the impression that only Tibbets and one other person aboard the Hiroshima mission knew the true nature of the "gadget" yet the names of the aircraft seem to indicate otherwise. For example "Necessary Evil", "Top Secret" and of course "Up an' Atom" (though I guess that plane could have been painted in the 3 days after Hiroshima). Did the crew members know the true nature of the mission before hand?
Thanks for contacting us. You are very perceptive. The two individuals you refer to were Col. Paul Tibbets and Navy Capt. William Parson, the Weaponeer (ie., the one charged with arming the bomb in flight). Although they knew all along what the mission was about, the entire Enola Gay crew was officially briefed before takeoff. As far as the names were concerned, only the Enola Gay was "named" prior to the mission. All of the remaining 14 aircraft were named after the Nagasaki Mission. Prior to that they were identified by number only.

Its not commonly known, but the loading pits were located within the area allocated to the 483rd sq. of the 505th bomb group of the 313th wing.  The aircraft of Captain Mel Cash was moved to allow the digging of the pit which was used to load the Enola Gay. In fact I walked over to the finished pit after it was lined in cement and it was used a number of times to load big orange practice bombs.  I have an e-mail message from Gen. Paul Tibbets confirming that he had "one pit on Tinian and one on Iwo Jima in case he had to abort the mission and return with the device" and it is signed Paul Tibbets pilot.  Would appreciate clarification, since I keep seeing pictures of two pits. Why would there be a need for two pits, we only had the two bombs, why load Bocks Car from another pit in that 72 hour time span.  By the way I don't remember seeing the second pit and I was up and down that taxi strip every day preflighting the 483rd planes every day.I have e-mailed this question to the General months ago and never received a reply.  I was shocked when I got the first response


The address you supplied cannot be found.  At least the message says the page cannot be found.  Also ,all I saw was a bare pit, no lifting device in the pit. I find it hard to believe that there were two completely different lifting devices.  Please give me a new address for information regarding these devices. What is your opinion on the Generals message telling me there was only one pit on Tinian?. Bill

Since the General said there was a pit on Iwo Jima I assume that means he thought they could make a safe landing there and I further assume they would have unloaded the bomb.  Did another lifting device exist on Iwo?.  And which one?

Hi Bill,

Here is the link again:

http://www.childrenofthemanhattanproject.org/CG/Photo-Pages-2/CGP-253.htm

Nothing was left to chance.  Due to the radically different designs of the two bombs, two separate lifting devices were manufactured by the 1st Ordnance Squadron.  These lifting devices not only lifted the bombs hydraulically into the B-29's but they also had to accept the different bomb carriers that carried the bombs to the pits.

As far as Iwo Jima is concerned, there was a special secondary bomb pit built there with the same lifting device as that for the Little Boy pit on Tinian.  When the Enola Gay took off with its 5 support aircraft, a 6th, "Top Secret", flew to Iwo Jima as a backup.  If the Enola Gay ran into mechanical problems, it was to fly to Iwo Jima where the bomb would be lowered into the pit there and then loaded into Top Secret.

Great web site. I have on tape the "20'th Century" episode called "Hiroshima", with Walter Cronkite from 1958. On that show, he states that the Enola Gay took off from Tinian and The Great Artiste and #91 took off from Iwo Jima and there they joined the Enola Gay. Is this correct? Sincerely, Bob Studley

Dear Bob,

Can anyone help me in finding pics of Katie's Kitchen? The internet so far is not helping!

We don't have any photos of Katy's Kitchen, but the following is a description for those that don't know.  The following was received from Ed Westcott, the official MED photographer at Oak Ridge: "Yes, Katy's Kitchen was the code name for concrete vaults built in the hillside at a remote area between Y-12 and X-10. The vaults stored highly enriched U-235 and the location was top secret. A farm barn was constructed to cover the entrance, a silo was built and stood at the side of the barn. The silo served as a guard watch tower. The facility appeared from the air like many abandon farm complexes scattered throughout the area. I was there in 1944 and 1945 and it was known as Katy's Kitchen."  Ed

 

12/17/02 - Great Site.

Also, according to "The Bomb" by Sidney Lens, "Fat Man" was the bomb exploded at Trinity, NM. Is this correct? Another question I have is about the Potsdam Ultimatum. Is there any place where I could find who signed the document? My last question has to do with the petition some Manhattan Project workers submitted to authorities. Where could I find a copy of this document and who signed it?

Dear Dan,

You are right in that the "Gadget" was the plutonium device detonated at Trinity. It has sometimes been referred to as "Fat Man" because it was the first of the "Fat Man" prototypes. The second was at Nagasaki followed by those at Operation Crossroads in 1946. All were based upon the gadget design.

Jumbo of course was an inert steel vessel that was originally designed to contain the "gadget" explosion. It was never used.

I am not sure who signed the Potsdam Ultimatum. Please check out the following links for information about the petition you refer to:

During the early days of the Manhattan project, a one of a kind printing press was taken over nightly by the FBI and secured so project personnel could print a "Black dot" What was that all about?

Now this is a long shot. There was a book published in the mid or late 60's that touched on this. It covered the project from beginning to end and was written so even I could understand it. It talked in length about the million holes per square inch of the material used for gaseous diffusion at Oak Ridge. What's the name of the book?

Hi Rod,

Thank you very much for visiting our web site and for your excellent question. The printing press you refer to was owned by the Chicle Company, manufacturers of chewing gum. The press was used to print labels at their NY plant. The "dot" process was used in the research associated with finding a suitable barrier for the gaseous diffusion process at Oak Ridge's K25 plant.

The book you refer to is "Manhattan Project - the Untold Story of the Making of the Atomic Bomb" by Stephane Groueff published in 1967. Still a very popular book, it is available at Amazon.com

My name is Phillip.

I was looking over you web site and I have found some information that has me puzzled. It is about the detonation time of "Little Boy" in the time line that you have posted. I have read several times that the bomb blew up at 8:16 am on the morning of August 6, 1945. This is the first I have seen or heard of this information happening 1 hour later. What info. can you give me on this.

Hi Phillip,

Thank you for visiting our web site and for being such a keen observer. The time line we show is taken from the official mission log book which is based on Tinian Island time, not Hiroshima time which is one hour earlier.

Greetings; I am majoring in history at The University of Texas at Tyler and researching WWII is my main focus. I have a question concerning how many Atomic bombs were available in August of 1945 for possible use against Japan. I have recently ran across a reference within a newspaper article that there were more than just the two which were used. This reference was made by the Salt Lake Tribune and also mentioned a pilot by the name of Charles D. Albury. If you can shed some light on this for me I would greatly appreciate it.
Michael Singleton,

There was a partially complete (minus the plutonium core) Fat Man atomic bomb on Tinian that could have been completed and used as a third bomb against the Japanese Empire if needed. The plutonium core stayed at Los Alamos and was stopped from being delivered to Tinian by orders from General Groves pending the course of the declared Japanese intention to surrender. This partially assembled bomb was held on Tinian in case the Japanese surrender collapsed. After the surrender, it was returned to Los Alamos in late fall and disassembled. 1st Lt. Charles D. Albury was the pilot on Bockscar, the B-29 that dropped Fat Man on Nagasaki August 9, 1945. Major Charles W. Sweeney was the commander on that mission.

Hope this helps. I will attempt to answer any further questions when I get back from a trip in a week. In the mean time, there are several excellent books I'd recommend regarding this topic.

I am not a history buff by any means but I am curious where they came up with the name for the Enola Gay. I have searched a few sites on the internet but most just mention the name of the plane and not the origin of the name. Thank you for your time.

Hi Staci,

Thank you for visiting our web site and for your often asked question.  The Enola Gay was named by Col. Paul Tibbets, the commanding officer of the atomic bomb raid on Japan, in honor of his mother, Enola Gay Tibbets.

Re Oak Ridge, TN: after WWII, uranium hexafluoride was shipped to K-25 in special containers; I understand that these containers were first used in 1946. During the war, was uranium hexafluoride produced on site, or shipped in using other containers, and how was it delivered? By rail?

From 1942, UF6 was shipped by rail to K-25 from Mallinckrodt (Mallinckrodt Chemical of St. Louis). All the containers were special because the gas is highly corrosive. Regards! Arnold

Can you give me any information on a husband and wife named Hall? They were physicists and may have been involved with a research reactor program at LASL.  Bernard Silverman
Thanks for visiting our web site and for your question.  Below is the brief information that I have.

Jane Hamilton was born in Denver in 1915.  She attended the Univ. of Chicago, where she received a BS in 1937, an MS in 1938, and a Ph.D. in Physics in 1942 (note her age).  While at Chicago, she married fellow student, David Hall.  The couple worked briefly as instructors of physics at the Univ. of Denver, and then in 1943, they joined the Physics Division at the Met Lab.  In 1944, DuPont lured them both away to work at the Hanford Engineer Works, where they (in their own words) babysat the construction and operation of the 3 reactors there.

Hi- Excellent web page!  Thanks for all your efforts! My apologies if this question is answered somewhere in your web site.  I recently had the good fortune to visit the island of Tinian and North Field. Can you tell me which runway (A,B,C, or D) was used by the Enola Gay for takeoff?  Thanks.   Lee
When we came down the hill from our camp, our runway was the farthest over toward the coast.  If the planes took off toward the north, our revetments would be to the west of the runways and we were the farthest west of the four.  Our parking area was possibly four or five hundred yards from the runway.  The planes were taxied to the loading pit and taxied back to their own revetments while awaiting takeoff time. I believe I told you about the incident involving the Enola's number one prop chewing up several yards of the revetment's coral while being swung around to face back out toward the entrance.  In case I didn't, I'll describe it again. When Walter McCaleb, the crew chief, was swinging it around in the revetment, he swung a little too wide and clipped the coral and bent the tips of the prop.  Nothing to do but change props with the Little Boy aboard and the revetment full of colonels, majors and even a few generals.  We had to push them out of the way to get the crane in and the other equipment  so we could work on the prop.  I think that was the fastest prop change in history.  We just barely managed to have it done in time for takeoff."

 

I have found out that my grandfather was with the military police at Los Alamos but he always told us he was cook there.  Did the MP's have their own cooks?

Do you know when the 1st atomic bomb was actually available? I've read that Little Boy was available several months before it was used at Hiroshima, and could have been used against Germany if someone had decided to use it, but have been unable to find anything saying when it was actually ready.  Any help you might be able to give would be appreciated. Thank you, in advance.

Actually, the mechanical/physical/electronic components of Little Boy were ready about 1 August.  They were still testing components at both Tinian and back at Los Alamos right up until that time.  However, the problem was the production of the highly enriched uranium (HEU) was not ready.  Although Oak Ridge was working around the clock, it was a very slow process yielding gram quantities at a time.  Toward the end, they were forced to alloy what little HEU they had with standard non-fissle uranium (tuballoy) to obtain the desired physical shapes for the target and projectile.  At that point the enrichment of those final pieces was down to only about 50%.  Los Alamos scientists used every last scrap of HEU they had in the lab at that time.  The HEU components for the projectile and the best available Little Boy target case, barrel, etc. were shipped to Tinian on the Indianapolis and the target pieces were ready for air shipment a week or so later.  Believe me, Groves and the scientists, many of whom were Jewish, wanted very much to let Hitler have the first bomb.  It just wasn't ready in time.  As you already know, the implosion device wasn't ready until after the success of the Trinity test.  You can tell the students that both bombs were being rushed into production at the greatest possible breakneck speed.  Groves was pushing everyone as hard as he could to get these bombs at the earliest possible date.  Unfortunately, neither Little Boy or Fat Man were anywhere near ready by the time Germany surrendered May 7, 1945.   Hope that helps.

Where did the scientists get the spare neutrons from, to bombard the uranium atom?

Thanks for visiting our web site and for your informed question.  Both the Little Boy uranium bomb and the Fat Man plutonium bomb used "initiators" for the burst of neutrons required to initiate the chain reaction.  The initiator was comprised of beryllium and polonium separated by a very thin layer of gold.  When the gold foil was punctured, the beryllium and polonium reacted to produce excess neutrons.

do you have any information on Elda Emma Anderson - physicist - who was also part of the making of the atomic bomb -- she also was involved with the manhattan project - thanks for your help - its for my son's science project

Here is some info on Dr. Elda Anderson:

Approx. 100 women were involved in physics research at the beginning of WWII.  Elda "Andy" Anderson received her Ph.D. from the University of Wisconsin in atomic spectroscopy.  She held a teaching position at Downer's College at Milwaukee.  The Cyclotron group at Los Alamos persuaded her to take a leave of absence from her teaching duties and move west.  She worked on studies of the fission process, including measurements of such basic parameters as the number of neutrons produced per fission and the time delay, if any, before the emission of neutrons.

She was 50 years old and with white hair seemed a senior citizen compared to the majority of younger scientists at Los Alamos.  She is remembered as living by herself in the dormitory and working mostly at night clad in jeans and a plaid shirt.  She was also the first person to prepare a sample of nearly pure uranium-235.

After the war, Elda returned to her teaching position at Downer's College, but was then recruited by the Oak Ridge Laboratory, where she was placed in charge of health education and training.  As a nuclear physicist, she played an important part in shaping the emerging discipline of health physics.

Hope the above helps

I recently saw the movie about the Manhattan Project "Little Boy & Fatman" and they showed a scientist that died of radiation poisoning prior to the test in Los Alamitos and I'm curious as to whether that individual was real and if so, were there others as well that died through radiation exposure or died in accidents directly related to the development of the Atomic bomb? I understand that Oppenheimer inevitably refused to get involved with the hydrogen bomb development and was later ostracized by the scientific community and the military. How true is th
