the military drones we have seen are HUGE.
I bet! Have seen 'birds' take unusual 'interest' in things and wondered about that myself, considering the DARPA research done. Personally am diggin the use of the bigger ones out here, got buzzed by one recently and back side of that thing reminded me of a school bus hehe Silent until it was 40-50 feet above me. Hope I gave em a chuckle :)
See several of them doing grids nightly.
Sleep better than we have in quite a while.
Thanks for the ((you.))
