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
Bluebird Mach 1.1 Bluebird Mach 1.1 Bluebird Mach 1.1 (CMN-8) was a design for a rocket-powered supersonic land speed record car, planned by Donald Campbell but thwarted by his subsequent death during a water speed record attempt in "Bluebird K7" in early 1967. Donald Campbell decided a massive jump in speed was called for following his successful 1964 LSR attempt in "Bluebird CN7". His vision was of a supersonic rocket car with a potential maximum speed of 840 mph, referred to as "Bluebird Mach 1.1". Norris Brothers were requested to undertake a design study. Campbell, ever superstitious, chose a lucky date to hold
