@Krieghund:
The fighter isn’t replaceable because the pilots were all American volunteers. The group was organized and established as military aid to China several months before the US entered the war. After the US entered the war, all pilots were needed for the US armed forces.
Technically, the unit shouldn’t even be in the game before the end of 1941, as that’s when it was actually activated. However, that wouldn’t be much fun, would it?
I just hope the flying tiger is protected better then in AA50, and Japan can’t kill it before you can use it. If I screw up and lose it then so be it. In AA50 we either slightly change set up to protect it, or allow the US to replace it once if its lost in the 1st round by flying a new one over(takes about 3 rounds) if China is still in the game at that point.
