The now obsolete Concorde had a cruising speed of Mach 2.2 This is about l500 MPH at the normal cruising height of the Concorde- 60,000 Feet. The Mach factor is constant only at sea level-760 MPH.- it decreases at altitude for a number of factors including the decreasing atmosphere and wind resistance (for this reason it is not normally applied to space vehicles outside the atmosphere, no atmosphere, no sonic velocity!) The Concordes had two speedometers,conventional and Mach at the two pilot stations, that is on both sides of the cockpit. For some reason the Red Line or absolute maximum safe speed (velocity never exceed) was never publicized.
The answer depends on how fast the plane is flying.
By his private plane.
105nots per hour
500,000
SST
An airplane can travel at a speed of 400kmph to 9000kmph.
612 miles per hour or 612 mph
The tsunami can flood as fast as a commercial jet plane.
150 MPH
the Cessna 406 can travel up to the speed of 455 km/h (283 mph)
plane
The Eurofighter Typhoon flies at about 1,320 mph at altitude.
