Dambusters Derwent flypast on 70th anniversary of raid
A Lancaster bomber has performed a flypast over Derwent reservoir, 70 years on from the historic World War II raid on German dams.
The reservoir was one of the sites where pilots practised dangerous low-flying ahead of their mission.
More than a third of the men never returned from the raids, which required them to fly 60ft above ground.
