Four attempted bombings took place exactly two weeks after the deadly 7 July blasts.
Once again, they were spread out around the capital and once again there were three on underground trains and one on a bus.
None of the devices exploded and police recovered a wealth of forensic material.
Three of the suspected bombers began their journey at Stockwell underground station. Failed devices were found on trains at Oval and Warren Street stations and on a bus in Hackney.
The fourth suspect entered the underground system at Westbourne Grove. A device was found on the Hammersmith and City line not far away at Shepherd's Bush.
A fifth device was found in a rucksack abandoned in bushes at Little Wormwood Scrubs two days after the failed attacks.
