Love to know more about the South African Cheetah's and the Israeli Kfir, they are somewhat of a mystery.
I wouldn't rule out Delta / BWB / Modified Flying Wing type config's being added to our fleet in the future...
XF-90. F-102. F-106. Area-ruled fuselage designs. The Dart was a great plane.
By the bye, I love taildraggers. Fueled them in my first real job out of high school.
I am working some into my science-fiction series: sort of Diesel Punk retro.
