Crashed military drone in Somalia designed to look like a bird
“What’s most interesting about this particular drone are its wings: in addition to looking like a bird, the wings will flap, although it looks like it’s actually powered by two sets of propellers. A quick glance at it flying overhead likely won’t attract a lot of attention, which is exactly what you’d want for a surveillance robot.
The US Army Special Operations Command has used a similar drone that can be fired out of a canon or deployed by hand. Like this drone discovered in Somalia, it has wings that can flap, making it appear like a regular bird flying overhead.”
