Here’s an image from February 2005 of Andre Agassi of the USA and Roger Federer of Switzerland playing a friendly tennis match on top of the helipad at the Burj Al Arab. The Burj Al Arab is one of the world’s most luxurious hotels and is located on a man-made island in Dubai.

I can only imagine that playing so high up must affect one’s game. I’d be so nervous of taking a misstep and falling off.
