There’s nothing like plunging in headfirst if you enjoy high-adrenaline sports such as sky-diving. This is just what this group of 108 daredevils did as they set about breaking a record in the skies above America. Hitting speeds of up to 180mph after they jumped from 18,000ft, they had 40 seconds of freefall to find each other and complete their formation. Once complete, it was largest number of skydivers to link up while falling headfirst.
