The unsung beauties no one knows of and the ambitious projects that failed to gain momentum are sometime sthe most interesting and beautiful aircraft. I'm talking particularly about airliner. The Lockheed Constitution, Ilyushin and Tuploev's failed attempts at a 4 engine piston engined airliner, lockheed's sst design, etc. Has any addon developer ever worked on those planes or planes like them?
On antother note, except for the ANT-20, FSX and FS2004 are completely devoid of pre-ww2 soviet civil aircraft, another area I'm interested in. Why don't any exist? Just the lack of information and photos?
