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 Rider Blue, further reinforcing the connection between the two series. The remix returned in later titles "Super Smash Bros. Brawl" and "Super Smash Bros. for Wii U". There is also a collectible Mach Rider trophy in "Melee", and a Mach Rider sticker in "Brawl". In "Mario Kart Wii", a vehicle called the "Mach Bike" resembles the bike in "Mach Rider". In addition, a similar vehicle also appeared in "Mario Kart 8", known as the "Sport Bike". In "", one of the many minigames is based on "Mach Rider".
