The fourth Airport film may be the silliest of them all, as George Kennedy returns, this time co-piloting with Alain Delon. The plane is on its way to the Moscow Olympics, has a bomb on board, and gets fired upon with missiles that necessitate flying upside-down. A look at the cast list resembles a bad episode of Fantasy Island, but it's always fun to see shameless touches like casting Mercedes McCambridge (Johnny Guitar) as the coach of the Soviet team. If you don't understand the significance of that choice, you may find this film more tedious than laughable, but fans of bad movies will have a field day, as Jimmie Walker, Charo, and -- oddly enough -- Bibi Andersson rub shoulders with high-altitude disaster.
