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.
Share to: Depending mainly on payload (how heavy the plane is), the jumbo jet takes off at speeds in the range of 180 to 220 mph (250 to 320 km/h), climbs at about 285 mph under 10,000 â¦ feet and from there it accelerates as it goes higher.
