The motocross rider in the video above is very fortunate that he was able to escape the accident with his life.
The rider missed a turn on the course and went airborne. As noted by James Baker on Sploid, YouTube user Justin McTamney claimed to be the rider who missed a turn on the course and went airborne. As you might guess, he claimed to have suffered some pretty wicked injuries.
The commenter alleges to have suffered a collapsed lung, broken scapula and five broken vertebrae. That sounds extremely painful, but it could have been much worse.
