Mach tuck significant in causing a tendency to dive, delta-winged aircraft with no foreplane or tailplane in the first case and, for example, the Lockheed P-38 in the second case. Alternatively, a particular design may have no significant tendency, for example the Fokker F28 Fellowship. As an aerofoil generating lift moves through the air, the air flowing over the top surface accelerates to a higher local speed than the air flowing over the bottom surface. When the aircraft speed reaches its critical Mach number the accelerated airflow locally reaches the speed of sound and creates a small shock wave, even though the
Mach Rider and obstacles on the road. The up and down buttons are used to shift gears. Mach Rider's bike has four speeds and shifting to the fourth gear at high speed will grant the player in instant speed boost. Conversely, the player remaining in a higher gear while stopping results in a slower acceleration. In each round, points can be scored by destroying enemies and certain obstacles with the machine gun. The number of points scored for destroying enemies and obstacles is determined by the type of enemy or obstacle destroyed. If the player blocks an attacking enemy by ramming it
