Dragonfly Spy and Candid Catfish
Rats. Another exhibit I'd like to see but can't, in this case because it's not even open to the public.
The CIA is celebrating the 40th anniversary of their Cool Gadgets Division (sorry, the Directorate of Science and Technology) with an internal exhibit at their Langley, VA headquarters. Among the spy tech are a 1970s laser-guided mechanical dragonfly complete with listening device, a robot catfish of untold function, and a camera the size of a coin.
Which reminds me, I seem to remember reading some young adult-level novel years ago about some kids and their scientist mentor, who operate a mechanical control dragonfly with a whole remote sensorium. Can anyone identify that one? The story might also have involved people being shrunk down to bug size.
