This was not the original movie with the crew becoming ill. " Zero Hour with Dana Andrews from 1957 was the same story as he had to fly the plane with only military experience that haunted him. There was one other that I can't seem to remember, but I think that it had Scottie from Star Trek involved. In any case it was definitely Zero Hour that was best known and was probably the reason behind Airplane's spoof and Terror in the Sky's sequel. The crew became ill from eating the same spoiled food and the flight attendant had to solicit from the passengers a new pilot. Andrews reluctantly became the man and overall it was quite entertaining.
