The Jet just looks like a 262 with a 109's fuselage. The Twin one was not a common variant, but it was also seen with the P51, there was a Twin Version of that aswell.
Thanks for this info however, I diddn't know they had designes for a Jet and a Twin 109 at all. Always looking for more Luftwaffe projects and what not.
I think the oddes I have come across is the flying Triangle. It never made it past the design stage because the ME163 won that contract. It was designed to do the same thing, but be smaller. I am glad we had something that looks like a modern airplane then something that looks like a Paper Airplane. I wish I could find pics of it, The only thing I have been able to find was in an old Luftwaffe book, and in a modle kit.
~~~UPDATE~~~
Actually I was wrong. The information I recieved was incorrect. The Flying Triangle was the Lippisch DM-1, And it was an unpowered glider as far as Luft46.com says. Thats the one I saw in the modle kit and in the old book.
