Air Force's Experimental Scramjet Hits Mach 5 | Military.com: The final flight of the X-51A Waverider test program saw the scramjet aircraft reach Mach 5.1 over the Pacific Ocean, the U.S. Air Force said Friday.
The unmanned hypersonic researcher craft traveled more than 230 nautical miles in just over 6 minutes Wednesday over the Point Mugu Naval Air Warfare Center Sea Range off California before crashing into the ocean as intended, an Air Force release said.
The X-51A took off from Edwards Air Force Base in California under the wing of a B-52H Stratofortress before being released at about 50,000 feet.
