"Words can not describe how stoked I am with landing the triple flip! It still amazes me that we were jumping a ramp that steep and high in the first place. Thank you everyone for your support!" Sheehan wrote on his Facebook page.
The jump took place at Travis Pastrana's "Pastranaland" complex in Frostburg, Maryland. Pastrana, who was the first to land a double blackflip on a motorcycle, founded Nitro Circus, a travelling daredevil show.
From Nitro Circus' website: "In a world where authenticity is rare, Nitro Circus is the only action sports entertainment company that delivers the biggest and best, mind blowing cross platform entertainment for daredevils and risk taking wannabes in the spirit of fun, friendship and camaraderie."
