Because that was not the SR-72. That was an informal designation for a program that started back then.

Im with you on this one blackswift and the "sr72" look nothing similar.
DARPA does not plan to conduct a third flight test of the HTV-2. The decision was made because substantial data was collected from the first two flights, and a third was not thought likely to provide any additional valuable data for the cost. The first flight provided data in aerodynamics and flight performance, while the second provided information about structures and high temperatures. Experience gained from the HTV-2 will be used to improve hypersonic flight.
