How fast did the Concorde fly?

Answer 1

At heights of up to 60,000 feet (over 18,000 meters), the Concorde cruised at around 1,350 mph (2,170 km/hr) - more than twice the speed of sound. It could make the trip from London to New York in less than three-and-a-half hours, cutting the time of a typical flight in half. With the five-hour time difference, in local time, the Concorde would land before it took off. A British Airways Concorde made the fastest Atlantic crossing, flying from New York to London in two hours and 53 minutes. On January 21, 1976, Concorde jet planes took off simultaneously from London Heathrow Airport and Orly Airport outside Paris, in the first commercial supersonic flights. The Concorde was never a great commercial success, and its first fatal accident - caused by a burst tire that ruptured a fuel tank and caused a fire and engine failure - resulted in the deaths of 113 people and marked the beginning of the end for the air service. It made its last regular commercial flight on October 24, 2003.
Concorde flew at Mach 2.2 - which is 2.2 times the speed of sound (2,162 kilometres per hour) not sure if that it fully loaded or empty though.
Concorde takes off at 220 knots (250mph) (compared with 165 knots for most subsonic aircraft). She cruises at around 1350mph - about 1 3/4 times the speed of sound - and at an altitude of up to 60,000 ft (over 11 miles high). A typical London to New York crossing would take a little less than three and a half hours as opposed to about eight hours for a subsonic flight. Travelling Westwards, the five-hour time difference meant Concorde effectively arrived before she left. She travels "faster than the sun".
The speed of Concorde is faster than the speed of sound that is why it also termed as super sonic plane. The speed of Concorde is about 1155 knots (2140 km/h or 1334 mph), more than twice the speed of conventional aircraft.
