FLR-PSA,
I would challenge you to look at the TV satellite industry. All over the world their signal is hyjacked and they have put billions into deriving an inpenatrible system. Everytime they think they have it licked, the hackers get back in. No matter where you are, for a couple hundred bucks and some reading you can gert free TV anywhere in the world and there is nothing they can do to stop you. Those UAV would constantly be going through costly hardware upgrades to combat takeover by a flying pirate(thats what I meant in my previous post).
2WingsOnMyWagon,
It would only be a matter of time before insurance companies would no longer insure UAVs if they were constantly getting hyjacked
