OXNARD, Calif., May 3 (UPI) -- 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.
