The third film in the Airport series finds a jet full of people 50 feet below sea level in the Bermuda Triangle. The oxygen supply dwindles for an art collector (Jimmy Stewart), the pilot (Jack Lemmon) and the other passengers (Christopher Lee, Brenda Vaccaro and Olivia de Havilland). The final installment takes place on the Concorde, which heads to the Moscow Olympics with a bomb aboard and must fly upside down after missiles are fired at it.
