(above and below) Three views of Jack McKay in the cockpit of X-15 no. 2 awaiting the start of mission 2-25-45 on 19 Jul. 1962. This would be McKay's first flight past Mach 5. Note in the photo below that someone has used their finger to inscribe "HOT STUFF" into the frost on the X-15's belly. Jack would attain Mach 5.18 (3,474 mph) at 85,250 feet.

— Jack McKay experiences a near fatal accident at Mud Dry Lake — |
||
|
|
|
The 74th mission of the X-15, and 31st for the no. 2 aircraft, began with B-52 takoff from Edwards AFB at 09:29 PST on Friday, 9 Nov. 1962. Jack McKay was at the controls for his 7th flight in the rocket plane. At 10:23:07 he dropped away from B-52 no. 008. Pressing the LR-99 throttle forward he only achieved 30 percent thrust, necessitating an emergency landing at nearby Mud Dry Lake. As he approached the lakebed, his flaps would not extend, so he experienced a much higher landing speed than normal, hitting the lakebed at 10:29:28, just over 6 minutes following launch. |
The excessive loads caused the left rear skid to fail at touchdown, starting a chain reaction that flipped the X-15 onto its back as it came to rest. McKay jettisonned the canopy just before the flip, fearing he would be trapped inside the cockpit when it rolled over. Without the canopy to protect him, the aircraft weight transferred to Jack's helmet, compressing his neck and crushing several vertebrae. He was dug out, flown to the hospital where he eventually recovered and flew 22 more research flights in the program. With the exception of the fatal accident of Michael Adams on 15 Nov. 1967, this was the most severe accident in the X-15 program. |

14 Feb. 1964: Just 15 months after the accident, X-15 no. 2 has been completely rebuilt and is rolled out of the North American Aviation plant in Los Angeles. This rocket plane is given a new designation as the X-15A-2. The fuselage has been expanded by 29 inches and two external tanks have been added for extra fuel and oxidizer, in order to extend the LR-99 rocket engine burn time by 60 seconds. This extra time under thrust could theoretically expand the speed envelope up to Mach 8. North American Aviation |
