Stock Photo - USA -- 17 Sep 1959 -- The X-15 #2 (56-6671) launches away from the B-52 mothership with its rocket engine ignited. The white patches near the middle of the ship are frost from the liquid oxygen used in the propulsion system, although very cold liquid nitrogen was also used to cool the payload bay, cockpit, windshields, and nose. This experimental jet was to help pave the way for NASA's manned spaceflight missions, one even piloted by Neil Armstrong himself -- Picture by Atlas Photo Archive/NASA.
