The Ministry of Defence has today released the Board of Inquiry (BOI) report into the tragic loss of two Royal Navy Submariners, and the injury of a third, following an explosion onboard HMS Tireless on 21 March 2007.

Tributes have quite rightly been paid to the whole Ship's Company of HMS Tireless over this very difficult incident. US forces, especially the helicopter pilot who volunteered to do the casevac at night over the ice cap, were also thanked and NASA have been particularly helpful with the scientific investigation.
