Heck, for Christmas day they should have aircraft dating from WW1 all the way up to today's aircraft in the game just for some excitement, and to watch a WW1 era Junkers vulch a B-2 spirit would be hilarious.
to do all that work for one day, and only 10 buisness days to do it, would be imposible, unless they worked round the clock and weekends too, even then im not sure it could be done. give them a few years of just this, and maybe, but itd ruin the integrity of WWII. and we are lacking many things in game that could make it better. to many examples to start with, but a He 11 is in high demand, wouldnt mind seeing one just ot shut some people up.
