Mach number a small area around the object's leading edge. (Fig.1b) Fig. 1. "Mach number in transonic airflow around an airfoil; M < 1 (a) and M > 1 (b)." When an aircraft exceeds Mach 1 (i.e. the sound barrier), a large pressure difference is created just in front of the aircraft. This abrupt pressure difference, called a shock wave, spreads backward and outward from the aircraft in a cone shape (a so-called Mach cone). It is this shock wave that causes the sonic boom heard as a fast moving aircraft travels overhead. A person inside the aircraft will not hear this.
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".
