Tonight: a rescue deep underwater. Exploring the waters where First World War battleships were scuttled at Scapa Flow in the Orkneys, two experienced divers got into trouble when one of them became pinned to the seabed by a huge metal door. With no time to go for help, it was up to his friend to save him, struggling to free him as their air supply streamed away. Plus, a reconstruction of a house fire in Nottingham highlights the dangers of making hoax calls, and an off-duty fireman plucks three children from the grip of quicksand-like coal slurry in South Shields.
