A B-52 Stratofortress carrying two H-bombs experiences trouble during a refueling operation, and in the midst of an emergency descent breaks up in mid-air over Goldsboro, North Carolina. Five of the six arming devices on one of the bombs somehow activate before it lands via parachute in a wooded region where it is later recovered. The other bomb does not deploy its chute and crashes into muddy ground at 700 mph, disintegrating while driving its radioactive core fifty feet into the earth.
