Shadows in a Desert Sea
Underwater photographer
Howard Hall developed special aqualung equipment that does not emit bubbles for this portrait of life beneath the Sea of Cortez, off the Californian coast. This enabled him to capture intimate film of such creatures as whale sharks, manta rays and sea lions. The film also reveals a threat lurking in the form of fishing boats, which trawl the seabed in a search for prawns.

This is not some Hollywood movie - this is the real thing. The third of this weekend's programmes about tunnels follows three ex-PoWs as they track down the entrance to "Harry", the tunnel they and 73 other RAF officers used to escape from Stalag Luft III during the Second World War.
It was an extraordinary undertaking. Five hundred officers were involved in the planning, security, tailoring, document forging, digging and underground railway construction.
Only three men got home safely. The rest were recaptured and 50 were shot by the Gestapo. After this, escapes were, in the words of the German propagandists, "no longer a sport".
