Note the multi-probe pressure rakes mounted around the nose of the X-15. The probes measured the airspeed at several distances from the skin of the X-15 simultaneously. The air closest to the skin of the rocket plane (called the boundary layer) moves slower than the air farther away. A special X-15 silhouette, pointing to the left, was added to the scoreboard on the side of the NB-52A to commemorate the return flight from Eglin Air Force Base on May 5. It appears at far right on the bottom. Photo courtesy NASA.
Major Allavie and Captain John Campbell were at the controls of the NB-52A on the morning of May 22. Jack Russel managed the systems of the X-15 using the launch panel controls, observing the rocket plane on the twin television monitors that occupied the space between his station and the pilot's seats.
After Rushworth launched the X-15-2 over Hidden Hills Lake, he was immediately aware that its roll stability was not as good as expected. He had to constantly counteract its tendency to roll to the left through the entire flight. At an altitude of 96,000 feet, an overspeed of the turbopump of the XLR-99 triggered an early shut down of the engine after a burn of 75.3 seconds, when the X-15-1 was going mach 5.03 (3,450 miles per hour). It was still climbing and reached a peak altitude of 100,400 feet, over 10,000 feet higher than planned. Rushworth dropped the nose slightly to get it back on profile, then pitched the nose up and down in controlled increments to collect the desired boundary layer flow data.
