A video from Brazil, but nothing to do with the Olympics: a couple of technicians apparently used to great heights perform some maintenance tasks on lightning rods along the statue of Christ The Redeemer's arms:
The statue of Christ the Redeemer (in Portuguese: Cristo Redentor) was built between 1922 and 1931 on top of the 700-metre Corcovado mountain, and for its construction reinforced concrete covered with soapstone (steatite, a metamorphic rock rich in magnesium) was used. The Polish-French designer Paul Landowski chose for an Art Deco style, but the head is the work of the Romanian sculptor Gheorghe Leonida. Actual construction was by the engineering duo Heitor da Silva Costa and Albert Caquot, a French national. The statue of Christ The Redeemer weighs 635 metric tons and has a height of 30 metres (98 ft), not counting the 8-metre (26 ft) pedestal. Its arms stretch 28 metres (92 ft) wide.
