The mach number is the speed of an aircraft, expressed as a fraction of the speed of sound in the atmospheric conditions in which the aircraft is flying. An aircraft flying at mach 1 is flying at the speed of sound.
the Mach number
Critical Mach Number has nothing (directly) to do with altitude. Mach Number has everything to do Temperature,

Mach Punch is not a TM so therefore it does not have a TM number.
Lower critical mach number may be defined as the highest subsonic mach number below which the entire flow over it is subsonic. vijayaprakaash
Mach number is dependent on a number of factors. Factors such as air density or altitude will change the Mach number. At approximatively 45 000 ft Mach 0.85 =289.2361 m/s = 1041.25 km/h = 647.0028 mph
Mach No at throat = 1.0
The collective nouns for aeroplanes are a flight of aeroplanes or a squadron of aeroplanes.
Critical Mach Number, or Mcr, refers to the lowest Mach number that air going over and around an aircraft can reach the speed of sound. If an airplane goes over its Mcr, handling might be greatly affected.
Aeroplanes are built streamlined to increase their flight efficiency. A number of other reasons are involved, but this is the main reason.
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.
