Program was cancelled in 1999 and discusses notional vehicles around which technology challenges and research time frames may be grouped. Chapter 3 describes five areas for new focused research to enable industry production by the year 2025 of an environmentally acceptable, economically viable commercial aircraft capable of sustained supersonic flight, including flight over land, at speeds less than approximately Mach 2.

level 9 Actual system flight proven through successful mission operations to be submitted to peer review and available data are insufficient to allow judging its viability. Rather than attempt to identify, evaluate, and compare the merits of individual breakthrough technologies, the committee concentrated instead on identifying problems and areas where breakthroughs and focused investment are needed to achieve the ultimate objective of sustained commercial supersonic flight, including flight over land.

The report prioritized aircraft performance requirements based, in part, on their contribution to meeting customer needs and the level of risk and concluded that more advanced R&T is needed to establish the feasibility of sustained supersonic commercial flight. It presented a plan to achieve a flight demonstration aircraft that would fully validate aerodynamic, propulsion, and flight control technologies.

In particular, at a time when manufacturers require a TRL 6 or higher to embrace complex new technologies in safety-critical aeronautics applications, NASA appears to be redirecting its technology investment strategy to achieve an end point of TRL 3 or 4. The likely result is a technology maturation gap that could jeopardize U.S.
