内容简介：
Visionary designer Jack Northrop built a series of experimental "flying wing" aircraft both before and during WWII. One of the most radical designs of the post-war era, the propeller-driven YB-35 bomber's all-wing design minimized drag and promised maximum payload capacity and terrific endurance. The YB-49, a turbojet powered variant built on the YB-35 airframe, forever altered aviation history and inspired the design of the B-2 Spirit stealth bomber. Originally printed by Northrop Aircraft in 1948, the YB-49 Flying Wing Pilot's Flight Operating Manual taught pilots everything they needed to know before entering the cockpit. Originally classified "Restricted", the manual was declassified long ago and is here reprinted in book form. This affordable facsimile has been reformatted, and color images appear as black and white. Care has been taken however to preserve the integrity of the text.
