I have thought for years that one day there should be a SINGLE GLOBAL AIRLINE
Okay, who is going to run this Single Global Airline, the UN? If it us the UN we need to go to the bone-yard and dust off all the remaining DC-6/7s and Connies, because that would how far back the UN would take the industry.
Possibly a good idea, however, as Europe can still not manage to operate under a single ATC structure I'm afraid it would unworkable.
