Crystal clear

摘要

The historic Crystal Palace transmission mast has been a landmark for lost travellers in the suburbs of southeast London for more than half a century. Towering over the boroughs of Croydon and Bromley, the huge 720ft lattice structure is considered by some to be one of Britain's major engineering feats. rnBut while many people view the structure as an rnunchanging cultural icon, behind the rnscenes engineers are making significant modifications to the steel mast in rnpreparation for the 2010 Digital Switch Over (DSO). The initiative is part of government plans to make Britain the world's 'digital capital' and will see transmission towers throughout the country overhauled in what is set to be the biggest and most complex re- engineering project in broadcast history.
