North American X-15 National Air and Space Museum photo D Ramey Logan. The X-15 was based on a concept study from Walter Dornberger for the National Advisory Committee for Aeronautics (NACA) for a hypersonic research aircraft. The requests for proposal were published on 30 December 1954 for the airframe and on 4 February 1955 for the rocket engine. The X-15 was built by two manufacturers: North American Aviationwas contracted for the airframe in November 1955, and Reaction Motors was contracted for building the engines in 1956.
Like many X-series aircraft, the X-15 was designed to be carried aloft and drop launchedfrom under the wing of a NASA B-52 mother ship. Air Force NB-52A, „The High and Mighty One“ (serial 52-0003, AKA Balls Three), and NB-52B, „The Challenger“ (serial 52-0008, AKA Balls 8) served as carrier planes for all X-15 flights. Release took place at an altitude of about 8.5 miles (13.7 km) and a speed of about 500 miles per hour (805 km/h). The X-15 fuselage was long and cylindrical, with rear fairings that flattened its appearance, and thick, dorsal and ventral wedge-fin stabilizers. Parts of the fuselage were heat-resistant nickel alloy (Inconel-X 750).[5] The retractable landing gear comprised a nose-wheel carriage and two rear skids. The skids did not extend beyond the ventral fin, which required the pilot to jettison the lower fin (fitted with a parachute) just before landing. #airbus #usairforce #instagramaviation #boeing #avporn #airforce #armedforces #fighter #fighterjet #fighterhelmet #fighterpilot #fighteraircraft #ejectionseat #military #militaryjet #militaryaircraft #us #usa #usn #usnavy #jet #aircraft #aviation #airplane #avgeek #avporn #soldier #gopro #goprohero #selfie #nasa by philippetondeur

And the sentient life on this planet kill each other over gods, and allow individuals with no scientific literacy to rule over their societies, allowing them to build pipelines, and factories that emit so much carbon gas that their planet will no longer habitable on the order of a few centuries, most of the population is almost completely scientifically illiterate, and condemn science. Any questions as to why we have not traveled to other stars? And colonized the milkyway? Or perhaps why we have not cured cancer? do YOU care? #earth #solarsystem #science #carlsagan #evolution #fuckgod #atheist #atheism #goodwithoutgod #palebluedot #voyager1 #nasa #space #spaceexploration #cosmos #universe #atheistcommunity #antitheism #banreligion2016 #stupidity #idiocy #astrophysics #cosmology #astronomy by interstellar_atheist
