TWA Flight 260 was the Trans World Airlines (TWA) designation for a flight from Albuquerque, New Mexico to Santa Fe, New Mexico in the 1950s. On February 19, 1955, the 40-passenger Martin 4-0-4 prop plane used by TWA for that route crashed into the Sandia Mountains. Initially believed to be the result of pilot error, the cause was revised to imply that the crash was the result of instrument failure.
