Xetro V..... Thank you for your reply, that is the sort of understanding I was trying to grasp! I'm sure that even the most cost-cutting technology-advanced company would find it hard to commision a pilotless aircraft in the commercial world. Even in ATC, boffins bark on about automating the whole system, but like in your situation what about emergencies? weather avoidance etc? I think its safe to say, Not in our life time!
Thanks again
