The fastest fighter aircraft is the MiG 25, with speeds topping at Mach 3.2 (2,450 mph/4,000 km/h). Pilots were not allowed to go beyond Mach 2.8. Above Mach 2.8, the engines would overheat and burn up.
Originally Answered: How fast is a commercial jet moving when it takes off and lands? âTypical takeoff air speeds for jetliners are in the 130â155 knot range (150â180 mph, 240â285 km/h). Light aircraft, such as a Cessna 150, take off at around 55 knots (63 mph, 100 km/h).
