FLIGHT OF THE CONCORDES: Is supersonic air travel set to return?
An aircraft developed by Boom Supersonic has become the first independently funded jet to break the sound barrier. The XB-1 aircraft accelerated to Mach 1.05 at about 35,000 feet during a test flight on Jan. 29 in the same Mojave Desert airspace in California where Charles “Chuck” Yeager was the first person to break the sound barrier in 1947.
