unknowingly until after a flight? I'm trying to recall a movie I saw in the 80s (I think) about a plane landing in the future which hasn't been physically made yet, its just all white and the past is eaten by monsters, leaving everything all white also. I think it follows someones life and his future is built before him and his past erased or eaten in this case until he catches up with the monsters responsible after this flight. That's all I've got sorry, any ideas?
