A major piece of Britain's industrial heritage crumbled to the ground on Saturday.
The first two of four 88 metre high cooling towers at Sellafield in Cumbria were exploded as part of the Calder Hall site's decommissioning.
Careful planning had been arranged for the explosion of the 289ft (88m) towers - which were officially opened by the Queen on October 17, 1956.
The operation is the first step to decommission the 167,000 sq m Calder Hall site which comprises 62 buildings.
The towers - which have reached the end of their lifetime and are no longer economically viable to maintain - contain asbestos.
