Regarding the new hangar(s).
Some posts further back mentioned that Eastern could up sticks and move it's base to another airport. Why should it. It has suitable hangar facilities for it's maintenance and a route stucture that allows aircraft to position back to Huy for maintenance without dead legging. What about the office staff. How many would not move if the company head quarters moved. Everything is in place. Don't fix what ain't broke.
Right the new hangar. Aircraft would have to dead leg in for maintenance. There are not established companies in the area that support heavy aircraft maintenance. There is not a ready supply of aircarft engineers in the local area. If contractors are used then there is a shortage of local accomodation.
So rather than speculate about new routes that could operate out of Huy, why not try and work out who would be prepared to fly there aircraft to Huy for maintenance....
