Just weeks after its first flight at the Mojave Air & Space Port in Mojave, California, XB-1 has secured the first-ever Special Flight Authorization (SFA) to Exceed Mach 1 from the Federal Aviation Administration (FAA). XB-1 test flights will continue to be conducted in the R-2508 Complex and supersonic operations, planned for later this year, will occur in the Black Mountain Supersonic Corridor and in a portion of the High Altitude Supersonic Corridor over Edwards Air Force Base (within R-2515 airspace) which has been used extensively for research and military supersonic aeronautical operations.
