We told you about Josh Dueck, the pro skier who broke his back in 2004 attempting a backflip. Since then, he’s gotten revenge against the mountains on a sit ski.

 He won gold in Mono skier X at the 2011 X Games and bronze this year in the same event. But on February 3, 2012, Dueck did what nobody has ever done: he completed the first ever backflip on a Sit Ski.
