Another crazy idea the Americans had was to use a pigeon to guide a missile to the target. The theory behind this was to train a pigeon to recognize a target by showing it images of it. The pigeon would peck on four levers (up, down, left, right) until the image was centered on the screen in front of it. They were trained to keep images centered on the screen and rewarded with corn. The pigeons did surprisingly well during training sessions at keeping track of images which jumped four or five inches a second on the screen. The program was canceled though and it was decided that electronic guidance would be a better option.

That's more awesome & at the same time more ridiculous than dolphin torpedoes.
