The unmanned X-51A WaveRider was expected to reach Mach 6 after it was dropped by a B-52 bomber off the Southern California coast near Point Mugu, but a faulty control fin compromised the flight.
"It is unfortunate that a problem with this subsystem caused a termination before we could light the Scramjet engine," Charlie Brink, the X-51A program manager, said in a statement. "All our data showed we had created the right conditions for engine ignition and we were very hopeful to meet our test objectives."
