I like the last sentence of this fact......"faster than the sun" ........very cool.
Concorde takes off at 220 knots (250mph) (compared with 165 knots for most subsonic aircraft). She cruises at around 1350mph - more than twice 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 takes 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 means Concorde effectively arrives before she has taken off. She travels "faster than the sun".
