Woow ! good post and good resume Katie. I will just disagree with very minor points. For instance , most FABs and FABEC in particular will not be a juridical entity that can become a service provider replacing the States. Will a group of States create a ANSP to control airspace, a bit like " The Tower Company" does for small airports ? In that case who will lead ? In FABEC Germany and France have totally oposite management visons are are unlikely to change in the next year, Germany because it is a ideological matter,(privatisation ) and France because it is the Unions that decide.(remaining inside the public service) The "smaller" states may also loose control of their destiny , and some egos ( read Dutch for instance ) will not allow that to happen. Same for deciding the future institutional arrangements for Maastricht .
I would not be surprised if Maastricht remains under Eurocontrol for some more years....
