9. The Pigeon-Guided Bomb
During World War II, American behaviorist B.F. Skinner proposed an innovative method for guiding bombs to their targets: using trained pigeons. The concept involved placing pigeons inside the nose cone of a bomb, where they would peck at a screen displaying the target image. Their pecking would steer the bomb toward the target. Despite successful demonstrations, the project was deemed too unconventional and was eventually abandoned. More details are available at Smithsonian Magazine.
