And now, thanks to a Freedom of Information Act request, it's known that they created a robot dragonfly to spy on us.
Newly-released CIA documents show how the espionage agency developed a robot dragonfly spy. The tiny aerial surveillance device – known as the "insectothopter" – was built in the 1970s according to the CIA Museum, where it has been displayed for 16 years.
But blueprints for the robotic insect were released this week by the U.S. spy agency to the website The Black Vault. Those blueprints reveal the finely honed microengineering behind the little spy machine.
