There was a pilot on board for takeoff and landing but the enroute section was remote controlled and it was in public airspace.
All other UAV flights I am aware of in Europe so far took place in protected airspace.
As it landed at Inverness, it must have flown in F and G airspace. EGPE has not yet got D airspace.
The BBC are rather behind the drag curve - that Jetstream has been doing flying of that nature in nonsegregated UK airspace for about 6 years.
