Insectothopter

The Insectothopter was a miniature unmanned aerial vehicle developed by the United States Central Intelligence Agency's research and development office in the 1970s. The Insectothopter was the size of a dragonfly, and was hand-painted to look like one. It was powered by a small gasoline engine to make the wings move and was fueled by a very small amount of gas. The project was abandoned when the Insectothopter was found to be too difficult to control in crosswinds.
