[*]Pipeline Through the Fens (1968) - extract. Subscribe: http://bit.ly/subscribetotheBFIThis striking documentary focuses on the construction of the hidden conduit for North Sea gas lurking under the picturesque Norfolk fenland. 'Pipeline Through the Fens' was filmed during the 12 weeks in 1968 it took to lay 43 miles of pipeline under the county.The film (made on behalf of The Gas Council) focuses on the considerable engineering achievement involved in linking sections of pipe (each one 40 feet long, 36 inches wide and weighing 4.5 tons) and burying them 9ft below the surface. The workers scrupulous care is understandable - you really wouldn't want to be trying to find a leak later on!
