This cringe-worthy high speed collision is an example of just how quickly things can escalate when angle flying.
One of the belly flyers in the group got a little low and too far ahead the formation. Instead of maintaining his heading and making gradual adjustments to get back on level, he turns almost 180 degrees to close the gap between him and the formation.
The end result is a head-on collision, a lost GoPro, and a helicopter ride to the hospital with 2 broken ribs and a broken vertebra.
Let's be honest, angle jumps are dangerous. Period. If you're new to angle flying, seek advice and coaching from an angle ninja at your local DZ or attend an angle flying skills camp.
