The 1958 Mars Bluff B-47 nuclear weapon loss incident was the inadvertent release of a nuclear weapon from a United States Air Force B-47 bomber over Mars Bluff, South Carolina. The bomb, which lacked the fissile nuclear core, fell over the area, causing damage to buildings below. [1] Though there was no nuclear detonation, six people were injured by the explosion of the bomb's conventional explosives. The Air Force was sued by the family of the victims, who received US$54,000, equivalent to $507,176in 2021. [2]

Description of incident

On March 11, 1958, a U.S. Air Force Boeing B-47E-LM Stratojet from Hunter Air Force Base operated by the 375th Bombardment Squadron of the 308th Bombardment Wing near Savannah, Georgia, took off at approximately 4:34 PM and was scheduled to fly to the United Kingdom and then to North Africa as part of Operation Snow Flurry. [3] [4] The aircraft was carrying nuclear weapons on board in the event of war with the Soviet Union breaking out. Air Force Captain Bruce Kulka, who was the navigator and bombardier, was summoned to the bomb bay area after the captain of the aircraft, Captain Earl Koehler, had encountered a fault light in the cockpit indicating that the bomb harness locking pin did not engage. As Kulka reached around the bomb to pull himself up, he mistakenly grabbed the emergency release pin. The Mark 6 nuclear bomb dropped to the bomb bay doors of the B-47 and the weight forced the doors open, sending the bomb 15,000 ft (4,600 m) down to the ground below. [5]

Two sisters, six-year-old Helen and nine-year-old Frances Gregg, along with their nine-year-old cousin Ella Davies, were playing 200 yards (180 m) from a playhouse in the woods that had been built for them by their father Walter Gregg, who had served as a paratrooper during World War II. The playhouse was struck by the bomb. Its conventional high explosives detonated, destroying the playhouse, and leaving a crater about 70 feet (21 m) wide and 35 feet (11 m) deep. Fortunately, the fissile nuclear core was stored elsewhere on the aircraft. All three girls were injured by the explosion, as were Walter, his wife Effie and son Walter Jr. Seven nearby buildings were damaged. The United States Air Force (USAF) was sued by the family of the victims, who received $54,000 (equivalent to $507,176in 2021). [2] [3] The incident made domestic and international headlines.

<i>Enola Gay</i> US Army Air Forces Boeing B-29 airplane that dropped the first atomic bomb

The Enola Gay is a Boeing B-29 Superfortress bomber, named after Enola Gay Tibbets, the mother of the pilot, Colonel Paul Tibbets. On 6 August 1945, piloted by Tibbets and Robert A. Lewis during the final stages of World War II, it became the first aircraft to drop an atomic bomb in warfare. The bomb, code-named "Little Boy", was targeted at the city of Hiroshima, Japan, and caused the destruction of about three quarters of the city. Enola Gay participated in the second nuclear attack as the weather reconnaissance aircraft for the primary target of Kokura. Clouds and drifting smoke resulted in a secondary target, Nagasaki, being bombed instead.

"Fat Man" is the codename for the type of nuclear bomb the United States detonated over the Japanese city of Nagasaki 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 nuclear explosion in history. It was built by scientists and engineers at Los Alamos Laboratory using plutonium from the Hanford Site, and was dropped from the Boeing B-29 Superfortress Bockscar piloted by Major Charles Sweeney.

Between 1948 and 1992, personnel and aircraft of the United States Air Force (USAF) Strategic Air Command (SAC) were routinely deployed to bases in England. An informal agreement to base SAC bombers in the UK was reached between US General Carl Spaatz, and Marshal of the Royal Air Force (RAF) Lord Tedder, in July 1946. At that time there were only three bases in the UK deemed suitable for operating Boeing B-29 Superfortresses: RAF Lakenheath, RAF Marham and RAF Sculthorpe. These were airbases that had been extended during World War II when there were plans to use B-29s against Germany. When the Berlin Blockade began in June 1948, two B-29 groups deployed to the UK, but neither was equipped with Silverplate bombers capable of carrying nuclear weapons. Nuclear-capable Boeing B-50 Superfortress bombers began deploying in 1949, and nuclear bombs followed in 1950.

<i>Bockscar</i> US Army Air Forces Boeing B-29 airplane that dropped the second atomic bomb

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 most recent – nuclear attack in history. One of 15 Silverplate B-29s used by the 509th, Bockscar was built at the Glenn L. Martin Aircraft Plant at Bellevue, Nebraska, at what is now Offutt Air Force Base, and delivered to the United States Army Air Forces on 19 March 1945. It was assigned to the 393rd Bombardment Squadron, 509th Composite Group to Wendover Army Air Field, Utah in April and was named after captain Frederick C. Bock.

Operation Snow Flurry was an operation by the United States Air Force that consisted of B-47 Stratojet bombers flying from South Carolina to England to perform mock bomb drops. Data would be received on the ground from the planes, and this would later be used to track the accuracy of the mock drops. Aircraft involved would then fly to Strategic Air Command airfields in North Africa. In 1958, a B-47 en route from Hunter Air Force Base accidentally dropped an unarmed Mark 6 nuclear bomb over Mars Bluff, South Carolina, although the explosion damaged nearby buildings. Live bombs were carried on board in case the planes had to activate for a wartime situation, but had their fissile nuclear cores removed and could not cause a nuclear detonation.
