Ursa_minor - 2009-05-06 I was hoping this would make it through the hopper.
Also, any design by Beriev, Blohm & Voss, and Arado get all my stars.
Tuan Jim - 2009-05-06 This looks like something an Italian guy dreamed one night after too much calzoni and then spent his life making it real.
Is there some aeronautical reason this plane is special other than looking so weirdly awesome?

They're not popular on airplanes and probably for good reason, but I haven't run the math to discover why.
