Static test number 1051 of XLR-11 engine at Edwards Air Force Base, on February 2, 1959. A technician walks past the engine just before it is fired up on the test stand. A jet flame comes out the engine.

Technicians look at remains of X-15-3 and its XLR-99 engine after explosion on test stand at Edwards Air Force Base. Various equipment kept on a ground. A cockpit of X-15. Ladder on either side of X-15. Technicians look at XLR-99 engine which looks completely destroyed. Front part of X-15 fuselage still intact.
X-15 first powered flight on Thursday, 17 September, 1959. (X-15 No. 2, tail number: 56-6671 with LR-11 engines. Scott Crossfield flew this mission at mach 2.11 and altitude 52,341 feet.) Scenes of several other X-15 powered flights are also shown. View of the water tower at Edwards Air Force Base, california. Overhead, NASA NB-52A, No. 003 and an F-100D chase plane, are seen at high altitude, with contrails behind them. The X-15, cradled under the B-52's right wing, drops clear, starts its rocket engines and begins its first independent powered flight, climbing rapidly away from the B-52. NASA camera tracks it, appearing as a moving white dot against the sky. The next sequences show later powered flights. View of NASA B-52 and three chase planes leaving contrails overhead. X-15 drops, its engines are running and falls behind the B-52, before accelerating rapidly, passing to its right, and continuing upward. Another scene shows brief glimpse of NASA B-52 overhead (no contrails). In final scene, X-15 is seen moving rapidly, leaving a long contrail behind it. Cloud then obscures the image somewhat.
View of a North American X-15 landing on a Rogers dry lake bed runway at Edwards Air Force Base, California. The camera follows the X-15 as it approaches in nose-high attitude and shows ground contact of its main skids and of its nose gear as it is lowered. The camera continues tracking the X-15 along the runway until it comes to a stop.
NASA B-52 (NB-52A, 52-003) landing at Edwards Air Force Base, California, following an unsuccessful X-15 launch mission. (The liquid oxygen tank pressure fluxuated due to a vent leak.) The B-52 makes a routine landing, deploying its drag chute on the ground roll.
