Realistically, if somebody bombed a shed somewhere, the base still ran missions. Doesn't matter if 1 plane was in that shed, 50+ more were dispersed in the trees, armored bunkers, scattered so widely that bombing 1 would not damage the other, etc.
Historically nobody ever put a field out of commission by dropping a bomb on a single building.
This is just an element of gameplay. I guess it's too hard to capture a field with the hangars up.
P.S. Capturing fields is also just a gameplay element! It's not MEANT to be historic!
