Drones with wireless video are available everywhere to anyone who can click and use a credit card.
I have seen 8 rotor drones for sale on line that could easily carry a small block of C4 with a blasting cap. I saw a news account where terrorists either in Afghanistan or Iraq had delivered an explosive that way and caused casualties.

There was a remote control helicopter with a video camera for sale at the local 7/11 convenience store. I'm sure it wasn't state of the art but it was only $50.
