The supersonic jet Concorde took its last flight on 24 October 2003 ending three decades of supersonic travel. The last transatlantic flight carried 100 celebrities from New York and touched down at 1605 BST at London Heathrow airport.
Concorde made its maiden flight on 2 March 1969 reaching a speed no higher than 300mph (480kph). It completed its first supersonic flight on 1 October 1969 when it reached a speed twice that of sound.
Supersonic means when something is faster then the speed of sound.
The speed of sound (Mach 1) is roughly around 700mph (it depends largely on altitude and the density of the air).
Yes, flying at more than twice the speed of Concorde and five times the speed of sound, the hypersonic airliner is set to be the future of modern air travel. The aircraft has a top speed of 3,400mph (approx. five times the speed of sound) and aims to fly between London (or Brussels) and Sydney in under five hours. The current flight time for airliners flying between England and Australia is 22 hours 50 minutes
