The servicemen who took part in the Second World War RAF Dam Busters’ raid - which involved training at Derwent Reservoir’s Ladybower Dam - have been commemorated with a gallery of photographs.
BBC News joined forces with Dam Busters’ enthusiasts to put together the online gallery of the heroes this week during the 70th anniversary year of the Operation Chastise mission.
