The point was for fun. Chewie posted the first few, I posted one with B-24's, Lancs, Brewsters and Zeros and it turned out to have more joiners.
Besides, if you want to close down a large field with a posted mission, you can't assign hangers to rank and file mission pilots and expect all hangers to go down. So we found that "area" bombing is more effective against a large field. As well as a super fun time.
