Amputee F3 racer Billy Monger: "You think nothing serious will happen to you"

Billy Monger's ambition to become a professional racing driver looked like it had come to a serious and tragic end when a crash on the track aged 17 resulted in both his legs being amputated - one above knee, one below. Talking with Emma Tracey, he looks back at how life changed after the accident, and the challenges he's put himself through since then. After breaking it to his parents his racing career wasn't over, he was back on the track within months. Since then he's raced in F3, taken part in BBC Two's Celebrity Race Across the World and most recently the Iron Man challenge - which is the subject of a new BBC documentary on iPlayer this week.
