Boom Supersonic continues to expand the flight profile and test capabilities of its XB-1 supersonic demonstrator, completing a fifth test flight on October 7 at the Mojave Air & Space Port in California. The flight is the third for the demonstrator in three weeks as Boom ramps up the test program with the goal of reaching Mach 1 before year-end.

Powered by three GE J85 engines producing a combined thrust of 12,300 pounds, the 71-ft-long, two-seat demonstrator first flew on March 22 and notched its second flight on August 26.
