Even more amazing considering it was built without the aid of computer design, models, and all the design/manufacturing software we take for granted.
My favorite, A10 Warthog. Built for close in combat, extremely maneuverable, quick, big gun, it's not called the tank killer for nothing. It can also stay in the air minus one engine, half a wing shot off, and with sections of the horiz and vert stabilizers gone. It also has armor for the pilot.
