Unfallbericht:
Pan American Flight 214 departed San Juan, Puerto Rico at 16:10 EST for a flight to Philadelphia with an intermediate stop at Baltimore. The aircraft, named 'Clipper Tradewind' arrived at Baltimore at 19:35 and took off again after refueling at 20:24. After contacting Philadelphia Approach Control the crew elected to wait in a holding pattern along with 5 other aircraft because of extreme winds at Philadelphia. Flight 214 entered a holding pattern west of the New Castle VOR on the 270 radial.
At 20:58 the airplane suffered a lightning strike. This caused the initial ignition of flammable fuel vapours inside the left reserve fuel tank. This triggered explosions in the centre and right reserve fuel tanks as well. Fuel spilled and caught fire; the complete left wingtip separated as a result. The aircraft was then seen to crash in flames. A 'Mayday' call was received by Philadelphia Approach as the plane was descending out of control.


PROBABLE CAUSE: "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."
