    The Mach number (M or Ma), often only Mach, (⫽ m ɑː k ⫽; German:) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound.

  2. Mach speed is when an object moves faster than the speed of sound, which varies depending on the atmospheric conditions. Learn about the different Mach numbers, from Mach 1 to Mach 3 and beyond, and how they affect the design and performance of aircraft.

  7. Nov 19, 2003 · A. Scott Crossfield piloted the D-558-II Skyrocket to Mach 2, twice the speed of sound, on Nov. 20, 1953, beating the Air Force and Navy to the milestone. The flight was part of a research program to collect data for future aircraft design and was the fastest record until Yeager flew the X-1A to Mach 2.44.
