This past weekend 17-time X Games medalist Travis Pastrana and many more of the world’s greatest action sports stars performed in the North American debut of Nitro Circus Live at the MGM Grand Arena in Sin City.

It was bound to be an exteraordinary evening when the show started with legendary  Pastrana asking his long-term girlfriend, Lyn-Z Adams Hawkins to marry him. From Pastrana himself, “I wasn’t supposed to do this until the end of the show, but I was so nervous I couldn’t wait. This is a night of world-first stunts, and this stunt involves the rest of my life,” Talk about romantic.

As if that was not enough excitement, Pastrana and Cam Sinclair landed the world’s first-ever, two rider synchronized FMX double black flip. Sinclair is a comeback kid who won the X Games FMX biggest trick in 2010, landing a perfect double back flip only one year after the same trick nearly took his life.

See Pastrana and Sinclair nail this trick for yourself!
