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 Five kind of terrain (firm, icy, unsteady ground, and significant slopes). Control G = Homing robot (As in the original) When pressed, the Mach Five releases a remote control robot bird capable of transmitting footage back to the Mach Five from wherever it is. This function wasn't used in the film. In the 1959 movie "On the Beach" Dr Julian Osborne (played by Fred Astaire) races in a white number 5 Ferrari while wearing a white helmet and goggles—eerily similar to Speed Racer in the Mach Five. In the animated 2008 series, which takes place about 40 years after the events
