X-15 Rocket Plane Onboard Time-Lapse Motion Pictures

The X-15 rocket-powered research aircraft could fly faster than 4,000 miles an hour and reached the edge of space in the 1960s. Edited footage from onboard time-lapse motion picture cameras looking aft and pointing toward the nose make a quick flight seem even faster as the X-15 launches from its B-52 mother ship, accelerates and climbs, and descends to a fast landing on Rogers Dry Lake at Edwards AFB, Calif.
