Video: Jumping off the world's tallest building

Scared of heights? Leave now, so.

Two sky divers - Vince Reffet (29) and Fred Fugen (34), both from Annecy, France - set a new world record when they jumped off the Burj Khalifa tower in Dubai.

That's 829.8 m (2,722 ft) straight down in a city centre.

The footage above was provided by SkyDive Dubai, who also shot this glossier version of the event from multiple cameras:

That's some impressive vertigo-inducing stunt work. It reminds us a little of the heart-pounding video of two free climbers who made their way up the under-construction Shanghai tower (650m, or over 2,000ft) in February - without a parachute.
