The Concorde's cruising speed was over twice the speed of sound, around Mach 2 (more than 1,300 mph). The speed of sound at sea level is approximately 761 mph, so the Concorde flew significantly faster than the speed of sound.

Concorde is special because it was the fastest passenger plane ever. It flew at Mach 2. It was made together by more than 5 different countries.
The fastest ever commercial airplane was Concorde. It flew at speeds of more than Mach 2. It retired from service due to crashes and accidents.
Mach 2.
The mach number is the speed, compared to the speed of sound in air. Thus, mach 1 is the speed of sound, mach 2 is twice (2 times) the speed of sound, mach 3 is 3 times the speed of sound, etc.
Mach 2 = 1,322.94 knots
No Mach 2.3
If it is civil , its mach 1.- mach 2 ,name is Concorde & in defence they go beyond mach 2
There is no plural for the noun 'mach'; the different levels of mach are usually shown by a numeral for various speeds, such as mach 1 or mach 2.
mach 1 = the speed of sound mach 2 is twice the speed of sound and that's how fast Concorde could travel, well, mach 2.3
