It might have been posted here before but this is a pretty neat site for vintage movies about the old warbirds. Lots of actual WWII and later training films showing flight characteristics, operations, etc. Just in case you were wondering how to properly take off and land that surplus P-51 or P-38 that's been sitting in the garage. Or maybe you and your friends have been wondering just what is the proper way to rendezvous and form up for bomber escort duty, or perhaps you need to know the proper Offensive Fighter Tactics for those pesky Zeros that have been buzzing around your airstrip.
