Mini-drones, hand-launched devices that can deliver small payloads on flights of 15-minutes or more. The Genie is out of the bottle and proof came in the form of a small drone found on the lawns of the White House.
The Secret Service is investigating. Initial reports say the drone was harmless.
This is a wake-up call. Technologies already on the market are incredibly sophisticated and they're cheap. They can fly remotely with GPS guidance or you can control them from your i-Pad or Android phone with a real-time wi-fi video link.
That's the civilian side of micro-drones. The military stuff is genuinely scary and it's almost certain that, at some point, a rogue state will pass along advanced drones to non-state actors - terrorists, insurgents, criminals you name it.
