When developing leading-edge defense technologies, things don't always go as planned. DARPA's experimental HTV-2 aircraft is capable of flying at Mach 20, or 20 times the speed of sound, for a few minutes at a time. However, a test of the system last August (HTV-2's second test flight) had to be cut short due to a "flight anomaly" that was most likely the result of degradation to its aero shell exterior. The HTV-2 initiative is tied to a DOD goal of being able to reach any destination in the world in less than an hour.
