There have been various conspiracy theories proposed about the bombings, including the suggestion that the bombers were ", based on claims about timings of the trains and the train from Luton, supposed explosions underneath the carriages, and allegations of the faking of the one time-stamped and dated photograph of the bombers at Luton station. Claims made by one theorist in the Internet video "7/7 Ripple Effect" were examined by the BBC documentary series "The Conspiracy Files", in an episode titled "7/7" first broadcast on 30 June 2009, which debunked many of the video's claims.
