Since everyone else here feels compelled to mention what planes should be added, I thought I should do the same.
So, without any further delay, here they are:
F4F-3/4 and FM-1/FM-2
P-39
P-40
SBD-3/5 Dauntless
TBD-1 Devestator
SB2C-4/5 Helldiver
PBY-3/3A Catalina
PBM-1 Mariner
F8F-1 Bearcat
F7F Tigercat
B-25 Mitchell
B-24 Liberator
B-29 Superfortress
P-47C/M and N (Need all the Jugs)
A-36 Apache
P-51 (the allison engined one)
P-38H
P-38J
F6F-3
F2A Buffalo
P-61 Black Widow
These I think are the absolute most important planes that need to be added.
