Daredevil motorcyclists Nitro Circus have back-flipped their way into the world record books, after leaping 40ft (12 metres) in the air - the equivalent of three London buses.
A team of 18 dirt bike riders set a new world record for the most motorbikes back-flipping in the air simultaneously during an action-packed stunt show at London's O2 Arena.
Officials from Guinness World Records confirmed 16 of the bikers were airborne simultaneously as they performed the back-flips, jumping a staggering 75ft (23 metres) and setting a new record.
One of the riders, 28-year-old Chris Birch from Cambridge said:
The record attempt was streamed to cinemas nationwide and followed by a screening of Nitro Circus: The Movie 3D.
