Amazing engineering

AeroVironment video showing progress with testing of a tiny flapping-wing “nano air vehicle” (NAV) designed to fly indoors. Testing culminated in a 20sec flight of an interim test vehicle, called Mercury, which demonstrated controlled hovering flight using a pair of flapping wings for propulsion and control. AeroVironment is now building a prototype for DARPA that will be samller, lighter and will closley resemble a hummingbird.
Now if they can reduce the size by 75% and make it fly as fast as a hummingbird does, and make it work outdoors, while still able to capture clear video from 100 ft or so in the air they will have a very interesting piece of surveillance technology – at that height and size it would be essentially invisible if not silent and would be near impossible to shoot down.
If it only works indoors it loses most of its usefulness as it would be easy to bat out of the air (even though doing that would give information as to the location of targets)
