I know it has been brought up before but....
Instead of killing hangers, kill the runway.
Maybe once a certain percentage of the surface has been damaged and 20,000lb of ord is dropped on it it becomes inop.
I think this would encourage full load out release from bombers instead of the precision bombing in game. It would encourage more people to fly some of the hanger queen's with the large light load outs , strategically and in tandem with the heavy hitters that people tend to fly more often. It will also help teach people to use the "." commands for bombing.
Planes could still spawn from the hanger they just couldn't spawn on the runway. This I think would kill the "vulch the runway" whiners.
It would be harder to capture a base but easier the cap. I think this adds a little more realisim to the field capture as well.
