The 109F and Spit V were available back on the 25th, and the 190 came in on the 29th. The Spit IX is coming on Thursday, and the B-17 and 109G2 will come in on Friday.
1940-42 was the period where the axis was most dominant and it wouldn't really be fair or much fun for those guys to just breeze over that so that we could get P-51's and Tempest's sooner.
