The bombing, the fourth and final attack to be covered by the inquests, took place at 0947BST - about an hour after the explosions at Aldgate, Edgware Road and Russell Square. The number 30 bus was torn apart in front of the headquarters of the British Medical Association, where a conference was being held. The inquests have heard that while medical equipment was lacking, dozens of doctors were on hand to offer lifesaving expertise. Picture of the bus in the Tavistock Square bomb attack. Louise Barry, who suffered injuries to her arm, leg and head, had been evacuated from the Underground at Edgware Road after one of the three earlier blasts, only to be caught in the explosion at Tavistock Square. The Australian at first thought she was having some kind of seizure, but then felt boiling water from the bus's radiator dripping on her arm. Thinking it was petrol, she described crawling through bodies to escape.

Plan of the train carriage in the Russell Square Road bomb attack

The most deadly attack on 7 July occurred on the Piccadilly Line between King's Cross and Russell Square. Germaine Lindsay, 19, detonated his bomb next to the rear set of double doors in the front carriage of the packed train just after it pulled out of King's Cross station. Twenty-six people were killed. Survivor Paul Mitchell told the inquest the carriage had been crammed when "an extremely loud pop and a very bright yellow light" went off. "It all happened so quickly. There was complete and utter pandemonium," he said. G ill Hicks lost both legs in the Russell Square blast but saved her own life by tying tourniquets to her severed limbs. She told the inquest she thought she was having a heart attack when the bomb exploded. She passed out and awoke on a seat to discover her injuries. She ripped her scarf in half and tied it around each leg before lifting what remained of them over the armrest of a seat.
