|A threatening note is found at an airport waiting lounge.
Left by an anonymous madman, the letter claims some murders will take place on Flight 502, a plane en route from New York to London.
Could it just be a hoax? Apparently not. As several folks meet their untimely ends - in flight - the pilot and airport security try to figure out who the psycho is...before others die!
Nice TV movie mystery with plenty of red herrings and a clever twist ending that's quite unexpected.
The large ensemble cast is good, with Bergen, Stack and lovely Fawcett-Majors in particularly fine form.
One of the better Airport inspired films of the '70s.
