Destination Moon (1950) (Movie)

format_quote Woody Woodpecker: Ha-ha-ha-HA-ha! It'll never get off the ground. Hmph - no propellers!
Cartoon Narrator: Rockets do not employ propellers. They use jets.
Woody Woodpecker: So do gas stoves, but they don't fly to the Moon.
Cartoon Narrator: Obviously you know nothing about rockets. Now, let's pretend that umbrella of yours is a shotgun.
(It turns into one)
Cartoon Narrator: Shoot it.
(Woody shoots and goes sliding backwards)
Woody Woodpecker: Who pushed me?
Cartoon Narrator: The gun, Woody. The charge not only fired out of the muzzle, it kicked back with equal force against the barrel.
Woody Woodpecker: Ahhh, it wouldn't happen again in a hundred times.
Cartoon Narrator: Shoot it at the ground a few times in rapid succession, and see what happens.
(Woody shoots and becomes airborne)
Cartoon Narrator: That same principle applies to rockets. It is the same shotgun kick of the explosives that throws the rocket forward. That kick, incidentally, is quite independent of the air around the rocket. It works just as well in a vacuum, or in outer space, which is a vacuum.

format_quote Dr. Charles Cargraves: You can't buck public opinion; I've tried. Have you seen this?
(Newspaper headline: MASS MEETING PROTESTS RADIOACTIVE ROCKET)
General Thayer: That isn't public opinion - it's a job of propaganda!
Jim Barnes: You're almighty right it is. Manufactured and organized - with money and brains. Somebody's out to get us.

General Thayer: I know one thing: unless these pills work, space travel isn't going to be... popular.
