Air-Attack.com News :: Joint UAS mission sets mark: First transatlantic flight for RQ-4A Global Hawk
Beyond LOS in International airspace has happened more than once already. As per the link.
It just requires knowledge of the system doing the flight and having the correct safety precautions built in. ie lost link logic/autolands etc.
Beagle - Please dont say you are comparing some 60s remote control plane to modern UAS aircraft?!
The technology is rapidly advancing but until organisations like the CAA catch up I doubt you will see them flying in UK airspace soon.
Although it is bad news for putting us out of jobs!
