One of my favorite modeling genres is "Luft '46," which is models of the crazy futuristic aircraft concepts Nazi designers were working on at the end of WWII. I just finished a new and very detail 1/32 kit of the Messerschmitt Projekt 1101, one of the few jet fighters that probably would have gone into production if the war hadn't ended when it did. As it was, only a prototype was built and never flown, but we studied the hell out of it and used some of its advanced features in our own jets, including the Bell X-5.
Nice.
Only German planes I have are a BF109 and ME 262
