There will be another service to commemorate the Dambusters raid today, this time in Lincoln Cathedral. The event will be attended by more than 1,300 people, including veterans of the raid Johnny Johnson and Les Munro, who has flown from New Zealand to be here.
Other relatives of those involved in the raids, including Guy Gibson's nephew and Mary Stopes Roe, the daughter of bouncing bomb inventor Barnes Wallis, will also be in attendance.
The service will be led by the Dean of Lincoln Cathedral, supported by the Chaplain in Chief of the Royal Air Force, and will be followed by a flypast by the Lancaster of the RAF Battle of Britain Memorial Flight and a pair of Tornado aircraft from 617 Squadron.
It follows last night's flypast infront of hundreds of people at RAF Scampton where the Dambusters mission began.
A Lancaster bomber recreated history this lunchtime by flying over Derwent Reservoir as part of the events to mark the 70th anniversary of the war-time Dambusters air raid. The dam in the Peak District's Hope Valley was used by airmen for practice runs ahead of their daring WWII operation.
