The Horror at 37,000 Feet

On a Boeing 747 flight from London to New York piloted by Captain Ernie Slade (Chuck Connors), a wealthy architect (Roy Thinnes) and his wife (Jane Merrow) have placed a druidic sacrificial altar in the baggage hold of the airliner. Aboard for the ill-fated trip are ex-priest Paul Kovalik (William Shatner) and millionaire Glenn Farlee (Buddy Ebsen). Soon after takeoff, crew and passengers alike face the supernatural horror that is unleashed from the baggage compartment — the ghosts of the druids, seeking revenge for being uprooted from their ancient home. After the demonic ghosts force the plane back towards London with gale-force winds, they begin freezing the plane's interior. The spirits then torment the passengers with horrific visions and feats of telekinesis. The passengers try to trick the ghosts by sacrificing a doll to them, but it only further angers the spirits. After a few of the passengers and crew are killed, Kovalik moves to the rear of the plane to try and determine what the spirits want. It turns out, they wish to be returned to their ancestral burial grounds, and they require a human sacrifice. An emergency door is then blown open and Kovalik is sucked out of the plane to his death, satisfying the ghosts. They then allow the 747 to land safely.
