On 14 March 1961 an aircraft accident occurred near Yuba City, California. A United States Air Force B-52F-70-BW Stratofortress bomber, AF Serial No. 57-0166, c/n 464155, carrying two nuclear weapons departed from Mather Air Force Base near Sacramento. The aircraft experienced an uncontrolled decompression that required it to descend to in order to lower the cabin altitude. Increased fuel consumption caused by having to fly at lower altitude, combined with the inability to rendezvous with a tanker in time caused the aircraft to run out of fuel. The aircrew ejected safely, and then the unmanned aircraft crashed west of Yuba City, tearing the nuclear weapons from the aircraft on impact.
