"Families of 60 men killed when the world's first underwater aircraft carrier sank in 1932 are to sail out to the wreck for the first time to mark the 80th anniversary of the tragedy. HMS M2, the first submarine to carry a two-seater biplane in a watertight hangar on its deck, is believed to have sank when the hangar door opened while the vessel was still submerged three miles off Lyme Bay in Dorset. All the crew were killed in the accident, including two airmen, and only two bodies were ever recovered from the wreck.
