This required about 40 to 50 men and took between 56 and 72 hours, depending on the skill of the bomb assembly team, and the Armed Forces Special Weapons Project had only three teams in June 1948. Dropped on Nagasaki, Japan, on August 9, 1945, Fat Man devastated more than two square miles of the city and caused approximately 45,000 immediate deaths. [53][54], After the war, two Y-1561 Fat Man bombs were used in the Operation "Crossroads" nuclear tests at Bikini Atoll in the Pacific. This has a far higher spontaneous fission rate and radioactivity than plutonium-239. "[27], The bomb was 128 inches (3,300 mm) long and 60 inches (1,500 mm) in diameter. 2 oz Red Bull® energy drink. [30], The explosion symmetrically compressed the plutonium to twice its normal density before the "Urchin" added free neutrons to initiate a fission chain reaction. Combined, the two atomic bombs caused as many as 220,000 deaths and most certainly brought a climactic end to a bloody war. The Harley Softail® Fat Boy® is one of the quintessential cruiser motorcycles. Dropped on the Japanese city of Hiroshima on August 6, 1945, it was the first nuclear weapon used in a war. The first was the "Gadget" detonated at the Trinity site on July 16, 1945. The plutonium core could not be left in for much longer, because its heat damaged the high explosives. It was obscured by cloud, as well, and Ashworth ordered Sweeney to make a radar approach. Michael Moros Detroit Boy 16. The theory is that the name is derived by combining the names of the two bombs that were … This redesign work was substantial, and only the Y-1222 tail design was retained. It was detonated on 29 August 1949 as part of Operation "First Lightning". [8], The implosion project remained a backup until April 1944, when experiments by Emilio G. Segrè and his P-5 Group at Los Alamos on the newly reactor-produced plutonium from the X-10 Graphite Reactor at Oak Ridge and the B Reactor at the Hanford site showed that it contained impurities in the form of the isotope plutonium-240. The Fat Man atomic bomb, dropped on the Japanese port of Nagasaki, used this design. [9] The prospect of more-efficient nuclear weapons impressed Oppenheimer, Teller, and Hans Bethe, but they decided that an expert on explosives would be required. It was more powerful than the unleashed on Hiroshima, weighing nearly 10,000 pounds and built to create a 22-kiloton blast. At the National Atomic Energy Museum, Albuquerque, New Mexico, USA, representative weapon casings for the Little Boy and Fat Man type weapons are on display. Fat Man var konstruerad enligt implosionsprincipen vilket innebar att en sfär av plutonium komprimeras av en omslutande sprängladdning, så att en kritisk massa erhölls. Implosion-type bombs were determined to be significantly more efficient in terms of explosive yield per unit mass of fissile material in the bomb, because compressed fissile materials react more rapidly and therefore more completely. The only way to use plutonium in a workable bomb was therefore implosion. [58][60], A nuclear strike would have been a formidable undertaking in the post-war 1940s due to the limitations of the Mark III Fat Man. The cores were transported to North Field, arriving on 2 August, when F31 was partly disassembled in order to check all its components. A crucial requirement was that the pieces be brought together in a time shorter than the time between spontaneous fissions. It weighed 10,300 pounds (4,700 kg). 1 Characteristics 2 Components 3 Notes 4 References Presenting the Fat Boy, for all your daily needs. Get your gingerbread fix year-round with this fat bomb recipe from Low Carb With Jennifer. "Fat Man" was the second plutonium, implosion-type bomb. As plutonium was found to corrode readily, the sphere was coated with nickel. The Fat Man was retired in 1950. Mechanical components were made or procured by the Rock Island Arsenal; electrical and mechanical components for about 50 bombs were stockpiled at Kirtland Army Air Field by August 1946, but only nine plutonium cores were available. They had been specially modified to accomodate the size and weight of the atomic bombs. It was built by scientists and engineers at Los Alamos Laboratory using plutonium from the Hanford Site, and it was dropped from the Boeing B-29 Superfortress Bockscar piloted by Major Charles Sweeney. "Little Boy" would come last and be named only to contrast to the "Thin Man" bomb. The design is based on John Coster-Mullen’s book "Atom Bombs, The Top Secret Inside Story of Little Boy and Fat Man", therefore, the dimensions are spot on. Fat Man adalah nama kode dari bom nuklir yang dijatuhkan Amerika Serikat di Nagasaki, Jepang pada 9 Agustus 1945.Pada saat itu Fat Man merupakan bom nuklir kedua yang digunakan dalam perang serta merupakan ledakan nuklir buatan manusia yang ketiga. The first was known as Gilda after Rita Hayworth's character in the 1946 movie Gilda, and it was dropped by the B-29 Dave's Dream; it missed its aim point by 710 yards (650 m). There were also the Y-1563 and Y-1564, which were practice bombs with no detonators at all. Bockscar, sometimes called Bock's Car, is the name of the United States Army Air Forces B-29 bomber that dropped a Fat Man nuclear weapon over the Japanese city of Nagasaki during World War II in the second – and last – nuclear attack in history. The weapon was already armed, but with the green electrical safety plugs still engaged. The Hiroshima Little Boy bomb used a total of 140 pounds of uranium-235. [21], The early Y-1222 model Fat Man was assembled with some 1,500 bolts. [12] Robert Christy is credited with doing the calculations that showed how a solid subcritical sphere of plutonium could be compressed to a critical state, greatly simplifying the task, since earlier efforts had attempted the more-difficult compression of a hollow spherical shell. The chain reaction starts when neutrons strike the heavy uranium or plutonium nucleus which splits releasing a tremendous amount of energy along with two or more neutrons which, in turn split more nuclei, and so on. 3 oz orange juice. It was the second of the only two nuclear weapons ever used in warfare, the first being Little Boy, and its detonation marked the third nuclear explosion in history. "[3] Conant consulted Ernest Lawrence and Arthur Compton, who acknowledged that their scientists at Berkeley and Chicago respectively knew about the problem, but they could offer no ready solution. The name “Fat Boy” was supposedly formed from the nicknames “Fat Man” and “Little Boy,” the designations given to the two atomic bombs dropped on Japan. All gun-type work in the Manhattan Project was directed at the Little Boy, enriched-uranium gun design, and the Los Alamos Laboratory was reorganized, with almost all of the research focused on the problems of implosion for the Fat Man bomb. Chock full of protein and satisfying fats, these fat bombs are the perfect bite-sized snack for those hectic days. The bomb had an explosive force (yield) of about 20,000 tons of TNT, about the same as the bomb dropped on Hiroshima. Lawn Boy 15. [15] The brittle α phase that exists at room temperature changes to the plastic β phase at higher temperatures. "Fat Man" was tested in July 1945. For other uses, see, Codename for the type of atomic bomb that was detonated over the Japanese city of Nagasaki on 9 August 1945, The detonation wave (arrows) is initially, Video footage of the bombing of Nagasaki (silent), detonated over the Japanese city of Nagasaki, National Museum of the United States Air Force, Atomic bombings of Hiroshima and Nagasaki, "Bockscar … The Forgotten Plane That Dropped The Atomic Bomb « A Little Touch Of History", Columbia university center for nuclear studies: Hiroshima and Nagasaki: The Long Term Health Effects, "United States Strategic Bombing Survey Summary Report (Pacific War) The Effects Of The Atomic Bombs", "Section 8.1.1 The Design of Gadget, Fat Man, and "Joe 1" (RDS-1)", "Plutonium: A Wartime Nightmare but a Metallurgist's Dream", "The yields of the Hiroshima and Nagasaki nuclear explosions", "Atomic John: A truck driver uncovers secrets about the first nuclear bombs", https://en.wikipedia.org/w/index.php?title=Fat_Man&oldid=999594063, Cold War aerial bombs of the United States, World War II weapons of the United States, World War II aerial bombs of the United States, Short description is different from Wikidata, All Wikipedia articles written in American English, Creative Commons Attribution-ShareAlike License. An explosive nuclear chain reaction occurs when a sufficient quantity of nuclear fuel, such as uranium or plutonium, is brought together to form a critical mass. Fat Charley 7. [11] The idea of using shaped charges as three-dimensional explosive lenses came from James L. Tuck, and was developed by von Neumann. It was also far more efficient – the Little Boy bomb fissioned about 1.5% of its available nuclear material, while the Fat Man bomb fissioned about 20%. This handy little baby packs all the power of a nuclear bomb, with little of the clean up! Little Boy and Fat Man On Display. Various combinations of stabilizer boxes and fins were tested on the Fat Man shape to eliminate its persistent wobble until an arrangement dubbed a "California Parachute", a cubical open-rear tail box outer surface with eight radial fins inside of it, four angled at 45° and four perpendicular to the line of fall holding the outer square-fin box to the bomb's rear end, was approved. [28], The plutonium pit[22] was 3.62-inch (92 mm) in diameter and contained an "Urchin" modulated neutron initiator that was 0.8-inch (20 mm) in diameter. Little Boy was a simplification of Thin Man, the previous gun-type fission weapon design. Production of the Mod 0 ended in December 1948, by which time there were still only 53 cores available. Nonetheless, it was decided that the plutonium gun would receive the bulk of the research effort, since it was the project with the least amount of uncertainty involved. Inventor of the Atomic Bomb This was the second of two bombs dropped on Japan that helped bring a swift end to World War II. [17] In drop tests in early weeks, the Fat Man missed its target by an average of 1,857 feet (566 m), but this was halved by June as the bombardiers became more proficient with it. In this gun-type device, the critical mass is achieved when a uranium projectile which is sub-critical is fired through a gun barrel at a uranium target which is also sub-critical. All rights reserved. Fat Man var konstruerad enligt implosionsprincipen vilket innebar att en sfär av plutonium komprimeras av en omslutande sprängladdning, så att en kritisk massa erhölls. "Fat Man" was the codename for the nuclear bomb that was detonated over the Japanese city of Nagasaki by the United States on 9 August 1945. He chose them based on their design shapes; the Thin Man was a very long device, and the name came from the Dashiell Hammett detective novel The Thin Man and series of movies. The committee concluded that any problems could be overcome simply by requiring higher purity. You can see the small signature of "W. S. Parsons, USN" or Enola Gay weaponeer Deak Parsons, to the far left, Fat Man is manually pushed to the bomb pit, Fat Man's alignment with the bomb pit is checked, The towing cable is disconnected. Fat bombs are the perfect portable way to round out your macros and slash your cravings on a ketogenic diet. Hiroshima & Nagasaki atomic bomb little boy & fat man were dropped on 06 & 09 Aug 1945 respectively. Expand your options of fun home activities with the largest online selection at eBay.com. Sweeney then proceeded to the alternative target of Nagasaki. This covered 70% of the area over Kokura, obscuring the aiming point. Features an openable warhead. [5], The gun-type and implosion-type designs were codenamed "Thin Man" and "Fat Man" respectively. 64 kg of Uranium-235, about 1.38% of the uranium fissioned Nagasaki's "Fat Man" gravity bomb 19–23 79–96 A "Fat Man" bomb was dropped over Nagasaki, Japan, on Aug. 9, 1945, near the end of World War II. The Fat Man was dropped and exploded at 11:02 local time, following a 43-second free-fall, at an altitude of about 1,650 feet (500 m). The "Fat Man" bomb would be round and fat and was named after Sydney Greenstreet's character in The Maltese Falcon. Neddermeyer was the only person who believed that implosion was practical, and only his enthusiasm kept the project alive. Harry Boy 14. Little Boy and Fat Man (136 K) Little Boy and Fat Man (65 K) The Combat Weapons. [23] Later versions included the Y-1560, which had 72 detonators; the Y-1561, which had 32; and the Y-1562, which had 132. Description These bombs are all general purpose high explosive bombs. The bomb designs were created by Robert Serber who chose the codenames according to the design shapes of the bombs. $29.50. The story of Fat Man and Little Boy isn’t new. Fat Man was the codename for the type of atomic bomb that was detonated over the Japanese city of Nagasaki by the United States on 9 August 1945. It was the second of the only two nuclear weapons ever used in warfare, the first being Little Boy, and its detonation marked the third-ever man-made nuclear explosion in history. Replacing the pump would take hours; moving the Fat Man to another aircraft might take just as long and was dangerous as well, as the bomb was live. In November 1945, the Army Air Forces asked Los Alamos for 200 Fat Man bombs, but there were only two sets of plutonium cores and high-explosive assemblies at the time. Von Neumann participated in the selection of a Japanese target, arguing against bombing the Imperial Palace, Tokyo. The fuzing of these bombs is the same except that the Tail Fuzes AN-Mk 230 and Mods and Mk 240 Mod 0 can be used in the 1,000-pound GP Bomb AN-M65, since this bomb has the Adapter Booster M115 (or M115A1). "Fat Man" was the second plutonium, implosion-type bomb. [8] The idea that, under such pressures, the plutonium metal itself would be compressed came from Teller, whose knowledge of how dense metals behaved under heavy pressure was influenced by his pre-war theoretical studies of the Earth's core with George Gamow. Crews were often rotated around during the missions. of about 16% of the fissile material present. [49], The target for the bomb was the city of Kokura, but it was found to be obscured by clouds and drifting smoke from fires started by a major firebombing raid by 224 B-29s on nearby Yahata the previous day. Little Boy and Fat Man On Display. Our mission at Fat Boy Drive-In is to keep the nostalgic 50’s aesthetic that so many appreciate. Fat Box 5. Little boy and the fat man were the code names of the atomic bombs dropped on Hiroshima and Nagasaki. Hearkening to the "hardtail" choppers of the '60s and '70s, the Harley-Davidson Fat Boy motorcycle keeps that heritage alive more than forty years later. The bomb dropped over Hiroshima was a uranium gun-type atomic bomb with codename ‘Little Boy’ while the one dropped on Nagasaki was a plutonium implosion-type atomic bomb with codename ‘Fat Man’. Bockscar was flown by Major Charles W. Sweeney and his crew, with Commander Frederick L. Ashworth from Project Alberta as the weaponeer in charge of the bomb. The name Fat Man refers to the early design of the bomb because it had a wide, round shape; it was also known as the Mark III. Attention then shifted to the even more malleable δ phase that normally exists in the 300–450 °C (570–840 °F) range. Little Boy and Fat Man In essence, the Little Boy design consisted of a gun that fired one mass of uranium 235 at another mass of uranium 235, thus creating a supercritical mass. The bomb destroyed 5 square miles of the city and caused about 140,000 deaths by the end of 1945. most popular drinks in this category... Ice Bomb. The bomb was dropped on Nagasaki, Japan, August 9, 1945, at 11:01 AM. [48] There was poor visibility due to cloud cover and the bomb missed its intended detonation point by almost two miles, so the damage was somewhat less extensive than that in Hiroshima. The North American B-45 Tornado, Convair XB-46, Martin XB-48, and Boeing B-47 Stratojet bombers had bomb bays sized to carry the Grand Slam, which was much longer but not as wide as the Fat Man. The only aircraft capable of carrying the bomb were Silverplate B-29s, and the only group equipped with them was the 509th Bombardment Group at Walker Air Force Base in Roswell, New Mexico. Gingerbread Fat Bombs. Harley Davidson Fat Boy 2011, Legacy Classic 2-into-2 Head Pipe Set by Magnaflow®. It was replaced by improved versions known as Mods 1 and 2 which contained a number of minor changes, the most important of which was that they did not charge the X-Unit firing system's capacitors until released from the aircraft. [11], The impracticability of a gun-type bomb using plutonium was agreed at a meeting in Los Alamos on 17 July 1944. The first of that type to be detonated was the Gadget in the Trinity nuclear test less than a month earlier on 16 July at the Alamogordo Bombing and Gunnery Range in New Mexico. [14], The task of the metallurgists was to determine how to cast plutonium into a sphere. Those names have long been burned into the historical conscience of the world. 43rd Bomb Wing 65th Bomb Squadron B-58 Hustler Model. All of the B-29s involved in the bombings of Hiroshima and Nagasaki and "pumpkin bomb" training and combat missions at Wendover, UT and on Tinian were Project Silverplate B-29s. It was the second of the only two nuclear weapons ever used in warfare, the first being Little Boy, and its detonation marked the third nuclear explosion in history. Three Fat Man high-explosive pre-assemblies (designated F31, F32, and F33) were picked up at Kirtland on 28 July by three B-29s: Luke the Spook and Laggin' Dragon from the 509th Composite Group's 393d Bombardment Squadron, and another from the 216th Army Air Forces Base Unit. Plus, they’re easy to customize with luscious flavors that … High explosives were manufactured by the Salt Wells Pilot Plant, which had been established by the Manhattan Project as part of Project Camel, and a new plant was established at the Iowa Army Ammunition Plant. The difficulties became apparent when attempts to measure the density of plutonium gave inconsistent results. The plastic shell had a 5-inch (130 mm) diameter cylindrical hole running through it, like the hole in a cored apple, in order to allow insertion of the pit as late as possible. A "Fat Man" bomb was dropped over Nagasaki, Japan, on Aug. 9, 1945, near the end of World War II. This page was last edited on 11 January 2021, at 00:09. Parsons said that Project Alberta would have it ready by 11 August, but Tibbets pointed to weather reports indicating poor flying conditions on that day due to a storm and asked if the bomb could be made ready by 9 August. The "Fat Man" atomic bomb, seen here, was dropped on Nagasaki, Japan. [37][38] The detonation released the energy equivalent to the detonation of 21 kilotons of TNT or 88 terajoules. [17][18][19] At the time, the B-29 represented the epitome of bomber technology with significant advantages in MTOW, range, speed, flight ceiling, and survivability. Plate with instruments (radars, baroswitches, and timers). The second bomb was nicknamed Helen of Bikini and was placed without its tail fin assembly in a steel caisson made from a submarine's conning tower; it was detonated 90 feet (27 m) beneath the landing craft USS LSM-60. Dell Boy 3. Magnesium was chosen because it does not act as a tamper. Bockscar, sometimes called Bock's Car, is the name of the United States Army Air Forces B-29 bomber that dropped a Fat Man nuclear weapon over the Japanese city of Nagasaki during World War II in the second – and last – nuclear attack in history. The Fat Boy is part of Harley’s Softail family and has been a favorite amongst enthusiasts. The Mod 0s were withdrawn from service between March and July 1949, and by October they had all been rebuilt as Mods 1 and 2. Fat Man being lowered and checked on transport dolly for airfield trip. 140 lbs; target - 85 lbs and projectile - 55 lbs, Target case, barrel, uranium projectile, and other main parts ferried to, Uranium target component ferried to Tinian via C-54 aircraft of the, Approx. While the chassis did receive a much-needed upgrade in 2018, the core ethos of … Great deals on Bomb Model. size of a softball, Plutonium core surrounded by 5,300 lbs of high explosives; plutonium core reduced to size of tennis ball, Efficiency of weapon: 10 times that of Little Boy, Approximately 1 kilogram of plutonium fissioned, Explosive force: 21,000 tons of TNT equivalent, Delivery:  B-29 Bockscar piloted by Maj. Charles Sweeney. [56], The Mark III Mod 0 Fat Man was ordered into production in mid-1946. The fuzing of these bombs is the same except that the Tail Fuzes AN-Mk 230 and Mods and Mk 240 Mod 0 can be used in the 1,000-pound GP Bomb AN-M65, since this bomb has the Adapter Booster M115 (or M115A1). After reviewing Neddermeyer's studies, and discussing the matter with Edward Teller, von Neumann suggested the use of high explosives in shaped charges to implode a sphere, which he showed could not only result in a faster assembly of fissile material than was possible with the gun method, but which could greatly reduce the amount of material required, because of the resulting higher density. Little Boy and Fat Man In essence, the Little Boy design consisted of a gun that fired one mass of uranium 235 at another mass of uranium 235, thus creating a supercritical mass. [25] Some minor changes were made to the design as a result of the Trinity test. [42][44], Fat Man F31 was assembled on Tinian by Project Alberta personnel,[41] and the physics package was fully assembled and wired. In the seventy-five years since, their use has been questioned, debated, and rebuked. [40], The first plutonium core was transported with its polonium-beryllium modulated neutron initiator in the custody of Project Alberta courier Raemer Schreiber in a magnesium field carrying case designed for the purpose by Philip Morrison. The missing tamper cylinder containing the pit could be slipped in through a hole in the surrounding 18.5-inch (470 mm) diameter aluminum pusher. These bombs killed more than 200000 people in Hiroshima and Nagasaki at that time. Add dry ingredients like almond flour, erythritol, and ground ginger to a bowl, … The fundamental thing was, of course, very much the same. Such a mass would make a sphere measuring about 8 inches in diameter. Fat Man was an implosion-type nuclear weapon with a solid plutonium core. Copyright © 2019 by the Atomic Heritage Foundation. The Army Air Forces wanted improvements to the design to make it easier to manufacture, assemble, handle, transport, and stockpile. The aircraft was … Dropped on the Japanese city of Nagasaki on August 9, 1945, it was the second nuclear weapon used in a war. Plate with batteries (to detonate charge surrounding nuclear components). This meant that the spontaneous fission rate of the reactor plutonium was so high that it would be highly likely that it would predetonate and blow itself apart during the initial formation of a critical mass. The Fat Boy is a portable nuclear bomb and weapon that was to be featured in the canceled Fallout: Brotherhood of Steel 2. Originally created with 3ds Max 2014 Model supports V-Ray and defualt Scanline Render [ USAGE ] Three days later, the U.S. dropped a second bomb, "Fat Boy," on Nagasaki killing an estimated 40,000 on August 9. It was nicknamed Fat Man . The design is based on John Coster-Mullen’s book "Atom Bombs, The Top Secret Inside Story of Little Boy and Fat Man", therefore, the dimensions are spot on. [10] The distance required to accelerate the plutonium to speeds where predetonation would be less likely would need a gun barrel too long for any existing or planned bomber. The only American bombers that could carry the Fat Man were the B-29 and the Convair B-36. [6], Neddermeyer discarded Serber and Tolman's initial concept of implosion as assembling a series of pieces in favor of one in which a hollow sphere was imploded by an explosive shell. "Little Boy" would come last and be named only to contrast to the "Thin Man" bomb. Powers and Stats. L. T. E. Thompson was brought in as a consultant, and discussed the problem with Neddermeyer in June 1943. Replacing the core also required the bomb to be completely disassembled and reassembled. Without the availability of the B-29, dropping the bomb would likely have been impossible. [18], Drop tests began in March 1944, and resulted in modifications to the Silverplate aircraft due to the weight of the bomb. [24] The final wartime Y-1561 design was assembled with just 90 bolts. [52] Most of the direct deaths and injuries were among munitions or industrial workers. Hearkening to the "hardtail" choppers of the '60s and '70s, the Harley-Davidson Fat Boy motorcycle keeps that heritage alive more than forty years later. To do this meant disassembling the bomb, and recharging took 72 hours. The "Fat Man" bomb would be round and fat and was named after Sydney Greenstreet's character in The Maltese Falcon. Thompson was skeptical that an implosion could be made sufficiently symmetric. [53], Mitsubishi's industrial production in the city was also severed by the attack; the dockyard would have produced at 80 percent of its full capacity within three to four months, the steelworks would have required a year to get back to substantial production, the electric works would have resumed some production within two months and been back at capacity within six months, and the arms plant would have required 15 months to return to 60 to 70 percent of former capacity. [20] High-speed photographs revealed that the tail fins folded under the pressure, resulting in an erratic descent. [39] About 30% of the yield came from fission of the uranium tamper. Delivery:  B-29 Enola Gay piloted by Col. "Fat Man" was the codename for the nuclear bomb that was detonated over the Japanese city of Nagasaki by the United States on 9 August 1945. The bombs, known as "Little Boy" and "Fat Man," were loaded onto bombers at the North Field airbase on Tinian Island in the Northern Mariana Islands, which are south of Japan. The atomic bomb, nicknamed Little Boy, is seen before being loaded into Enola Gay's bomb bay on Tinian. The depleted uranium tamper was an 8.75-inch (222 mm) diameter sphere, surrounded by a 0.125-inch (3.2 mm) thick shell of boron-impregnated plastic. The lead-acid batteries which powered the fuzing system remained charged for only 36 hours, after which they needed to be recharged. One of the most enduring myths around a motorcycle in the industry is the reason this Harley Davidson classic was named the “Fat Boy” is that it was named after the bombs dropped over Hiroshima and Nagasaki. [1] Richard C. Tolman suggested an implosion-type nuclear weapon, but the proposal attracted little interest. Tour some of the key locations of the Manhattan Project with an audio guide. 64 kg of Uranium-235, about 1.38% of the uranium fissioned Nagasaki's "Fat Man" gravity bomb 19–23 79–96 Total weight of nuclear material and bomb was 98.8 - 100.2 kg Hiroshima's "Little Boy" gravity bomb: 13–18 54–75 Gun type uranium-235 fission bomb (the first of the two nuclear weapons that have been used in warfare). The bomb designs were created by Robert Serber who chose the codenames according to the design shapes of the bombs. Ashworth changed them to red after ten minutes so that Sweeney could climb to 17,000 feet (5,200 m) in order to get above storm clouds. The footage also depicts the mushroom cloud above Nagasaki.
