In 2005 skateboard professional Bob Burnquist nearly died in one of his first attempts to jump his board into the Grand Canyon after completing an impressive 50-50 grind.
He lived and performed his spectacle and landed safely by parachute .
Perhaps it was because of the calculations made while designing the ramp and taking into account the surroundings that he did not crash.
