More highlights of last year's series, reconstructed with the emergency services, actors and the people involved in the original rescues. This week: the 6-year-old boy who toppled into the gorilla pit at Jersey Zoo who was saved by one of the keepers and a local ambulance man. A rescue 500 feet beneath the North Sea when a diver's face mask shattered and the bizarre accident that left a motorist impaled on a 40 foot scaffolding pole.
