Beijing -based Space Transportation is working on a supersonic jet that's even faster than NASA 's 'Son of Concorde' The Yunxing jet's engine reached Mach 4 or 3,045mph four times the speed of sound.
This is twice as fast as the defunct Concorde 's max speeds (Mach 2 or 1,338mph ) and three times that of NASA 's X-59 plane.
Yunxings will be made of lightweight, high-strength composite materials, designed to withstand extreme aerodynamic heating while travelling at Mach 4 .
Other reasons for the demise of Concorde were high fuel costs, concern over its noise and a preference for lower fares over speed. No government or manufacturer has since been able to build a commercial plane that can travel faster than the speed of sound..
