Mach tuck

Shock wave above wing moves rearwards as aircraft speed approaches Mach 1

The P-38 Lightning gave Lockheed engineers a great deal of initial design trouble because it was so fast that it was the first American aircraft to experience compressibility and Mach tuck.

Mach tuck is an aerodynamic effect whereby the nose of an aircraft tends to pitch downward as the airflow around the wing reaches supersonic speeds; the aircraft will first experience this effect at significantly below Mach 1. This speed is known as the critical Mach number of the wing.
