This movie is scary at times, perhaps no more so than when a naked George Kennedy tells his hooker girlfriend he wants a little more sugar. Thankfully his nakedness is covered by a blanket, but the image is still more horrifying than anything you're likely to find in, for example, Schindler's List.
The dialog in this film was inspiring; it inspired me to watch another movie. In one scene, when a stewardess remarks about male pilots, Kennedy asks, "Why do you think it's called a 'cock' pit?" Charming.
And yes, contrary to what some have written, this film is very, very bad.
