In northwest China, China successfully tested the Feitian 2, a new hypersonic vehicle. This test marks a major step forward ...

Many of the physics concepts that are in play during normal flight also apply to an aircraft going faster than the speed of sound. However, there are also other properties that need to be considered.

Two weeks ago, Boom Supersonic’s XB-1 demonstrator plane made history when it broke the sound barrier over the continental United States, reaching 750 miles per hour (Mach 1.12) near Barstow, ...

If you've been keeping tabs on aviation news as of late, you saw that Boom Supersonic just recently broke the sound barrier with its XB-1 demonstrator aircraft. Oddly enough, no one on the ground ...

In this case, the XB-1 took advantage of a physics phenomenon called the Mach cutoff. Because sound moves more slowly at higher altitudes, an aircraft breaching the sound barrier at those heights ...

Boom Supersonic's XB-1 demonstrator jet became the first U.S.-made civilian supersonic jet to break the sound barrier. The independently funded XB-1 reached a speed of Mach 1.122, or about 750 mph ...
