The Twilight Zone: And When the Sky Was Opened

Two astronauts, recently returned from a flight with an experimental plane called X-20 that mysteriously disappeared from radar screens for 24 hrs, meet in a hospital room where one recovers from a broken leg. One of them, Col. Forbes (Rod Taylor), remembers the journey and the following events quite differently. For one, there was a third member on that flight, one Col. Harrington, that has not only disappeared from yesterday's newspaper story but that the injured Major Gart has no recollection of.

The night before, Forbes and Harrington went to a bar, when Harrington suddenly started feeling peculiar, like he 'doesn't belong'. When calling his parents, he learns that they don't know him and he is not their son. Shortly after, he vanishes into thin air and nobody in the establishment remembers Harrington ever being there. In fact, nobody at all remembers any Harrington.

Eventually, the two remaining army men realize that they, too, 'don't belong'.
