Aussie Window Washers Rule
The Burj Dubai (Dubai Tower) really is an amazing accomplishment.
Earlier in 2009 Dubai looked like it was on the verge of a financial meltdown. It was rescued by Sheik Khalifa of Abu Dhabi. The tower has been renamed the Burj Khalifa in his honour.
At 2700 feet it is massively taller than the previous record holder, Taipei 101, which stands at about 1500 feet.
And all those windows are being washed by an Australian company, Cox Gomyl.
Cox Gomyl spent $12 million designing and installing gondolas on telescopic booms which can reach every part of the tower.
