'Royal Oak torpedo' blown up at sea off Orkney
Navy bomb disposal experts have detonated a World War Two torpedo found in Scapa Flow in Orkney.
The weapons is believed to have been fired by German U-boat U-47 when it attacked the battleship Royal Oak in October 1939.
The loss of the ship while it was moored in Scapa Flow claimed the lives of 800 sailors.
A number of U-47's torpedoes failed to explode at the time of the attack.
Local historian Tom Muir and Lieutenant Commander Tony Hampshire have been speaking to BBC Scotland's David Delday.
