Interestingly enough the story was pretty big in the German media.
Germany had a project for about the same thing in the '30s during the Third Reich:
Silbervogel, German for silver bird, was a design for a rocket-powered sub-orbital bomber aircraft produced by Eugen Sänger and Irene Bredt in the late 1930s for The Third Reich/Nazi Germany.
and it came to the...
On 18 October 1985 Messerschmidt-Boelkow-Bloehm (MBB) began renewed studies of the Sänger spaceplane, this time a "piggyback" two-stage-to-orbit horizontal takeoff concept.
so this US Air Force hypersonic rocket is nothing new.
and then there was this DARPA thing that they said had reached Mach20
Superfast Military Aircraft Hit Mach 20 Before Ocean Crash, DARPA Says

A superfast unmanned military plane traveled at 20 times the speed of sound and managed to control itself for three minutes before crashing into the Pacific Ocean in a recent test, military officials said.
While the X-51A Waverider is designed to fly only at six times the speed of sound.
