Pan Am Flight 100 was a scheduled passenger flight from La Guardia Airport to Shannon Airport operated by Pan American World Airways on 30 January 1949 with a Lockheed L-749A Constellation, collided in mid-air over Port Washington, New York, with a Cessna 140 that was on a local flight from Meriden Airport [a] . The Constellation sustained substantial damage but landed without casualties at Mitchel Air Force Base. The Cessna crashed, resulting in the death of the pilot and the sole passenger. [1] The Civil Aeronautics Board attributed the collision to the failure of both pilots to observe and avoid each other. [2]
The pilot in command of the Constellation was George F. Knuth, who was later killed in 1963 while serving as the captain of Pan Am Flight 214. [3] [4] Passengers aboard the Constellation included English theatre producer Harold Fielding and Laszlo Halasz, director of the New York City Opera. [5]
