Fifteen months before the London bombings, MI5 had seen them. They had names, photographs, and addresses. Two of the men who would carry out the 7/7 attacks had already appeared in surveillance. And then… they vanished back into the noise.

In this second episode of our 7/7 series, 20 years on from the attacks, David and Gordon unravel one of the most haunting questions of the entire investigation: could the 7/7 bombings have been stopped? Through forgotten files, garbled intelligence, and missed opportunities, a chilling pattern emerges - one where small decisions, fractured systems, and scarce resources combined to let something slip through.

Follow the threads of Operation Crevice, eavesdropped conversations, and badly cropped photographs. Watch as one name - Mohammad Sidique Khan - surfaces again and again, just beneath the surface. The dots were there. But no one connected them.
