A special programme remembering the London bombings 20 years on. Audrey talks to two men connected by the explosion at Edgeware Road Station.
David Gardner was reading the script of a Shakespeare play when the bomb went off. He lost a leg and the hearing in his left ear. 22-year-old David Foulkes was killed on his first work trip to London. He had accidentally boarded the wrong tube. His father Graham talks to Audrey about the enduring loss of his best friend.
We also speak to two experts in trauma about the impact such an event can have on the human body and mind, and how people can be taught to deal with such trauma - Jo Dover is a specialist who works with victims of international terrorism and Sara Cook is a conflict response specialist.
