On 7 July 2005 at 09:47am, a Stagecoach London Dennis Trident 2 double-decker bus, fleet number 17758, registration LX03 BUF, was damaged a lot in a terrorist attack by Hasib Hussain, who took a bomb onto the bus and exploded it, killing 13 other people on the bus as well as himself. The explosion ripped the roof off the top deck of the bus and destroyed the back of the vehicle. The explosion took place close to the British Medical Association building in Tavistock Square. The bus was off line of route and on a different route than usual due to earlier multiple attacks on the London Underground system. The bus was replaced by the first Alexander Dennis Enviro400 produced, named "Spirit of London" as a tribute to the attacks.
