The Man Who Never Was1956

Lieutenant George Acres:
Monty, that parachute that didn't open... Suppose we were to drop a fellow out of a plane over enemy territory, with papers on him saying we were going to invade Greece, and his parachute didn't open. The Germans would find him dead, and the papers, and "Aha," they'd say, "Look at this. Officer with secret papers, parachute didn't open... they're going to invade Greece."

Lieutenant Commander Ewen Montagu:
Do we tell the man who jumps that the parachute doesn't work, or is it a sort of practical joke that he finds out on the way down?

Lieutenant George Acres:
Well, of course it would have to be somebody you didn't mind much about.

Lieutenant Commander Ewen Montagu:
Are you volunteering? No, George, it wouldn't work.

Lieutenant George Acres:
What about using a man already dead?

Lieutenant Commander Ewen Montagu:
The autopsy would show he was dead before he hit the ground. Let's get back to the office and think again.
