A Pan American . . .
A Pan American World Airways, Inc. Boeing 707-121, N709PA, Flight 214, crashed at 2059 e.s.t., December 8, 1963, near Elkton, Maryland.
Flight 214 was in a holding pattern awaiting an instrument approach to the Philadelphia International Airport when it was struck by lightning. Immediately thereafter, the aircraft was observed to be on fire. A large portion of the left wing separated in flight and the aircraft crashed in flames approximately ten nautical miles southwest of the New Castle, Delaware, VOR. All persons aboard, 73 passengers and eight crew members, perished in the crash and the aircraft was destroyed.
The Board determines the probable cause of this accident was lightning-induced ignition of the fuel/air mixture in the No. 1 reserve fuel tank with resultant explosive disintegration of the left outer wing and loss of control.
