    The CIA developed dragonfly drones in the 70s IIRC, though they had no active electronics and were heated by a laser to guide them (and possibly to measure acoustic vibrations). It’s not clear whether they found a practical use for them.

      From what I’ve read, they weren’t practical to use as keeping the laser on them was very difficult.

      That’s the public info, of course. Maybe it worked very well.
