Horror in 37.000 Fuss - The Horror at 37000 Feet (1973)

Fly the not-so-friendly skies in this frightening tale of survival at 37,000 feet! On a flight from London to Los Angeles, a wealthy architect (Roy Thinnes) and his wife (Jane Merrow) have rented out a jumbo jet`s entire cargo hold to transport a precious artifact - an altar from an ancient abbey. But they`re unaware of its deadly secret.

Aboard for the ill-fated trip is William Shatner as a drunken, cynical ex-priest; Buddy Ebsen as an arrogant millionaire; and Chuck Connors as the heroic pilot. Not long after departure, crew and passengers alike face airborne jeopardy and supernatural horror as a demonic entity escapes from the altar, seeking to possess a hapless victim as well as seek revenge on those who would desecrate the sinister deity's ancient ritual site. Fasten your seatbelts - it`s going to be a terrifying flight!
