Professional tennis players Roger Federer and Andre Agassi played an unranked game on the helipad of the Burj Al Arab Hotel, which was temporarily converted into a grass tennis court, at a height of 211 meters. The helipad has no borders or fences on the edges and if a player hit a winner the tennis balls would plunge down to the ground.
