Scott Murray attempted a double backflip at X Games 13 (2007), but failed to complete the trick as Travis Pastrana did at X12 (2006). No analyst seemed to see the real reason why Murray failed though -- they all said he didn\'t have enough speed. But seems to me that his boot foot slipped off the peg, causing him to stall in the spin.
