This is how fast an aeroplane actually travels! How fast do planes actually fly? Exploring airplane speedsAn airplane’s speed varies by phase, but commercial jets cruise at around 880-926 km/h (550-600 mph), taking off at 240-290 km/h and landing slower, while military jets and experimental craft can reach supersonic or hypersonic speeds, like the SR-71 Blackbird’s 3,540 km/hour. | The Asian Chronicle
