10. The Pigeon Camera
During World War I and II, pigeons were outfitted with tiny cameras, capturing aerial reconnaissance images before the widespread use of aircraft and satellites. This method showcased the creative use of available animal technology. The CIA developed a small, lightweight camera that could be strapped to a pigeon’s breast, allowing it to fly over targets and capture detailed photographs. However, the effectiveness of this technique was limited, and it was eventually discontinued. (cia.gov)
