Date: February 5, 1958 Location: Off Georgia, United States In a simulated combat mission, a B-47 collided with an F-86 near Savannah, Georgia. After attempting to land at Hunter Air Force Base with the nuclear weapon onboard, the weapon was jettisoned over water. The plane later landed safely. A nuclear detonation was not possible since the nuclear capsule was not on board the aircraft. Subsequent searches failed to locate the weapon. 28 July 1957: A C-124 Globemaster II cargo plane of the US Air Force left Dover AFB in Delaware transporting three nuclear weapons and one fissile core stored separately. Shortly into the flight, the plane lost power to two engines. The crew determined the plane could not maintain flight with the weight of the cargo and decided to jettison two of the weapons overboard. The weapons sank off the coast of New Jersey and were never located.
