my first sketchup airplane! The North American Aviation XB-70 Valkyrie was the prototype version of the b-70 nuclear bomberfor the United States Air Force's (USAF) Strategic Air Command. Designed by North American Aviation in the late 1950s, the Valkyrie was a large six-engined aircraft able to fly Mach 3 at an altitude of 70000 feet, which would have allowed it to avoid interceptors, the only effective anti-bomber weapon at the time. #air #aircraft #airplane #american #atitude #aviation #b70 #bomber #canard #cold #command #engine #experimental #fastest #flight #force #gear #high #intercontinental #jet #mach_3 #nasa #north #nuclear #parachutes #plane #record #research #speed #states #strategic #supersonic #turbojet #us #united #usaf #war #wing #xplane #xb70 #xf108
