On 16 May 1943 the nineteen 617 Squadron Lancaster bombers, converted to carry 'UPKEEP' took off from RAF Scampton, beginning their journey to Germany.
Flight Lieutenant H.B. 'Mick' Martin piloted one aircraft flying in the first wave to attack the Möhne Dam. This extract from Martin's Pilots Flying Log Book details the members of his crew as well as basic information about the flight itself.

To commemorate the 65th anniversary of the "Dambusters" Raid the Royal Air Force Museum in conjunction with the Newsdesk Media Group has produced a new book "Breaching The German Dams - Flying into History" which uncovers elements of hidden history crucial to the success of 617 Squadron's attack on the German Dams in May 1943.
