Very iconic, engrossing, and mostly good episode. Bob Wilson (William Shatner) is the passenger with a fear of flying who comes face to face with tragedy and madness in the form of a gremlin. The big drawback here is the gremlin looks quite ridiculous. Despite that, Shatner is excellent as the man who hopes he's recovered from a mental breakdown. The wife is played by Christine White (from 'The Prime Mover', season two) and her expressions say it all- that he must have finally flipped. Enjoyable, and in some ways memorable as Shatner fearfully looks out of through the rain soaked window. Oddly for the era, the man is seemingly hysterical while the wife and air hostess (Asa Maynor) are calm and protective. Great piece of television.
