It flew about as well as you'd expect (60-second flight time, no tolerance for wind) but what a cool bit of mechanical design! No idea how that "laser beam" control works. From Engadget
Back in the '70s, the CIA needed some kind of miniature flyer to deliver an audio bug, and after considering (and rejecting) a faux bumblebee, decided that a robotic dragonfly would be the best option. The wee UAV used a "miniature fluidic oscillator" as a motor and was propelled by a small amount of gas. It was somehow guided by a laser beam, which served double-duty as the "datalink for the audio sensor payload," according to the CIA Museum. Unfortunately, the insect-based mech proved too difficult to control, especially with any degree of wind, and was eventually scuppered -- all that's left of the now-declassified project is in the video after the break.
