In short, Petty suggests that Apt did his job too well and may have been pushed to exceed Mach 3 by the AFFTC and conflicting priorities within it. Petty quotes Base commander
General Stanley Holtoner: "I think that every supervisory guy from me on down has criticized himself, because if we had told this boy to stop at a specific speed, this wouldn't have happened."

As the capsule fell for several minutes to the desert floor, he did not exit so that he could use his personal parachute before ground impact, and was killed. The aircraft continued to fly in a series of glides and stalls before landing and breaking into three pieces (separate from the capsule). A proposal to salvage the aircraft and modify it for a hypersonic test program was not approved. The aircraft was scrapped.

With nozzle extenders and a longer than normal motor run, Apt flew an extraordinarily precise profile; he became the first man to exceed Mach 3, reaching Mach 3.2 (2,094 mph, 3,370 km/h) at 65,500 ft (19,960 m).

The Bell X-2 had a prolonged development period due to the advances needed in aerodynamic design, control systems, materials that retained adequate mechanical properties at high temperature, and other technologies that had to be developed. Not only did the X-2 push the envelope of manned flight to

The subsequent investigation into the X-2's fatal flight raised numerous contributing factors into the crash—largely focusing on Apt's decision to turn the aircraft while still above Mach 3. Some cited his lack of experience with rocket planes, but, as historian Chris Petty notes, "he had in fact

The flight had been flawless to this point, but shortly after attaining top speed, Apt attempted a banking turn while the aircraft was still above Mach 3 (lagging instrumentation may have indicated he was flying at a slower speed or perhaps he feared he was straying too far from the safety of his
