The Invaders1967

Narrator:
[Opening Narration] A physician reports the death of a woman. Two hours later, her husband, a NORAD Major, reports her very much alive. The news accounts attracted no particular attention. But David Vincent knew that an alien, unconscious without pulse or heartbeat, might easily be mistaken for dead, even by a doctor. So he arranged to visit NORAD's Combat Operation's Center, 1,400 feet below Cheyenne Mountain and a natural target for the Invaders.
