1948. Northrop YB-49 jet flying wing in flight

 


Most recent photo of Northrop YB-49, new jet version of the famed Flying Wing bomber, shows slim, clean lines in flight at 12,000 ft. over Mojave Desert near Muroc Air Base, Calif. Test flights on the YB-49 got under way immediately after its Oct. 21, 1947, first takeoff and have continued steadily ever since. Trouble-free jet engines offer ground crew contrast to failure-plagued gearbox system of XB-35 propeller-driven bombers. Second YB-49 has been completed and is scheduled to fly away from Northrop's Hawthorne, Calif., plant early in January of this year.
