A deafening sonic yawn signs off this desperate finale to Universal's Arthur Hailey-inspired quartet of in-flight entertainments.

Aeronautically and otherwise, it's a bumpy trip.

Unintentional comedy still seems the Airport series' forte, although excellent special effects work, and some decent dramatics help Concorde take off.

Settling for Martha Raye, the fourth "Airport" saw the Polident shine fade from an all-star cast. Instead, it becomes a sometimes quite literal "Hollywood Squares" spinoff with eventual panelists Jimmie Walker & Charo, and eventual host John Davidson.
