Critical Mach number and slow down as it travels around the aircraft's structure. When the aircraft's airspeed reaches the critical Mach number, the speed of the airflow in some areas near the airframe reaches the speed of sound, even though the aircraft itself has an airspeed lower than Mach 1.0. This creates a weak shock wave. As the aircraft exceeds the critical Mach number, its drag coefficient increases suddenly, causing dramatically increased drag, and, in an aircraft not designed for transonic or supersonic speeds, changes to the airflow over the flight control surfaces lead to deterioration in control of the aircraft.

Mach 1 Racing Mach 1 Racing Mach 1 Racing was a NASCAR Winston Cup Series team. It was owned by Hollywood stuntman Hal Needham and actor Burt Reynolds. The team made its debut in 1981, fielding the No. 22 Skoal Pontiac driven by Stan Barrett. Barrett ran ten races for the team that season, his best finish coming at Talladega Superspeedway, where he finished 9th. Midseason, Mach 1 created a second car, the No. 33, driven by Harry Gant. Gant did not win that season, but he won three poles and had thirteen top-tens, finishing third in points. In 1982, Gant drove the
