Instead of a huge revamp, there's room for just adding a couple new planes (like the Mig 15, Sabre, etc) and having them inactive in the MA but available for special events (like Korea based weekend events).
I know planes aren't free, but if someone at HTC is up to doing it, their work shouldn't be crapped all over by the people here on the BBS because it doesn't have to be active in the MA.
