Photos: Fun time: Novak Djokovic joins the Crown Prince of Dubai in his private wind tunnel

Defending champion Novak Djokovic took some time out of his preparations for the 2014 Dubai Duty Free Tennis Championships on yesterday Sat.Feb 22 by taking to the Dubai skies. Well, sort of.

The Serb and world No2 was a guest of Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum, Crown Prince of Dubai, at his private wind tunnel, operated by Inflight Dubai. Djokovic, a four-time winner of the ATP 500 event in the UAE, was joined by his head coach Boris Becker, his brother Marko, and his friend and fellow player, Carlos Gomez-Herrera.
After a pre-flight briefing from instructor Brad Cole, Djokovic braved the wind tunnel which is powered by four huge turbine engines and can reach top speeds of over 320 kilometres an hour.
The Crown Prince is a keen sky diver and as Djokovic, Becker and Co found out, this is the closest you can get to really jumping out of a plane!
