I know some of you saw all the CH-46's being used for the movie and it almost out. Here is a article on where they got the idea. Also the Great LA Air Raid event and Ft. MacAuthur is also the same event but based on aircraft.

I'm planning on watching just for the aerial footage. Looks kinda crappy otherwise, but I'm a sucker for military aviation in cinema. ;D
