said in the article the current planes are the ones that are not limited AT ALL!

only the Ta152, Spit XIV, Me262,F4u4,La7,B-29,Tempest, Ki84,Me163,P-47N,yak3,Arado Ar234,C54(able to drop 50troops!!!!) would be the onese that must be earned.
frankly I see it as the best method for controlling the amount of these planes seen in AH, it should have different amounts of dificulty to obtain each aircraft for sure.
man a b29 and c54 would rock

and they are definitely planes that should be earned not handed out at certain time intervals.
