Investigation Summary
The disappearance is one of the most enduring mysteries of the Cold War. The aircraft was transporting Brigadier General Paul T. Cullen and his staff to England to activate the 7th Air Division, a unit intended to spearhead potential SAC operations against the Soviet Union. After reporting a fire in the cargo hold, the crew performed a successful controlled ditching. A B-29 Superfortress arrived on scene and confirmed the aircraft was intact on the water and that the crew had successfully evacuated into five-man life rafts equipped with survival gear and 'Gibson Girl' emergency radios. However, the B-29 was forced to depart due to low fuel. When the USCGC Casco arrived at the coordinates 19 hours later, the rafts and men were gone. The subsequent search, one of the largest ever conducted, found only minor debris showing signs of a fuel fire on the water's surface.
Final Conclusions
The official Air Force investigation concluded that the aircraft was largely intact upon impact, evidenced by the lack of floating debris like aircraft tires. While a fire occurred on the water's surface, the ultimate fate of the 53 men remains undetermined. The presence of Soviet vessels in the area and the strategic importance of the passengers have fueled long-standing theories of kidnapping or sabotage, though no conclusive evidence of Soviet involvement has ever been found.
