From Dive Magazine News:
Technical divers have recovered the body of their colleague who died while filming a sunken German U boat 16 miles off the coast of County Donegal, north west Ireland. Michael Henrahan, 45, a father of four from Dublin, was one of four divers sent to dive and survey the70m-deep U778 wreck.
The underwater expedition by the Dive North West team was part of a scheme to raise the submarine and display it in a museum in Northern Ireland. The team made several attempts to rescue Henrahan, but were forced to leave him and surface.
‘Out of the blue, Mick just fell back on to the wreck and I think he had some sort of seizure,’ Paul Lewis, a member of the dive team told a local radio station. ‘Instantly I went to his aid, but it was of no help to him.’
The team returned with the help of police divers to recover his body.
Lisahally, the main port of Derry, witnessed the mass surrender on 8 May 1945 of the remains of the U boat fleet. U778, which did not see any war action, sank while being towed from Scotland to Londonderry.
