UAV's, eye in the sky, spy planes, call them what you will, dependant on the size, everything you read is true.
Hard to knock down, the smaller ones can be hand launched and typically only contain a camera and a return to launch feature. The larger ones can be armed, and frequently are, recovery of the larger UAV's is effected in Africa by having a large truck fitted with a catch net, they literally fly the returning UAV into it!
Do it now, you may never get another chance
