Daredevils climb one of London's tallest buildings

If you're prone to vertigo... you might want to look away as this incredible video follows two adrenaline junkies as they make their way out to the tip of a crane, 784 feet up over the city of London.

Without the safety of ropes or harnesses, Syed Bukhari and Owen Reece climbed to the top of the Landmark Pinnacle building.

Ascending 75 flights of stairs and scaling a wet crane in the rain to the summit the currently under construction building-which will soon be tallest residential structure in Europe.
