Imagine a secret weapon from World War II unlike any other: missiles guided by live pigeons! This wasn't science fiction, but a real project led by psychologist B.F. Skinner. Under Project Pigeon, birds were trained to recognize and peck at enemy targets displayed on a screen inside the missile. Their precise pecks would actually control the bomb's steering. To improve accuracy, they even developed a system where three pigeons worked together, with the majority ruling! While the military ultimately passed on this feathered guidance system, calling it a "crackpot idea," the research provided fascinating insights into animal behavior...
