This happened at a New Mexico ski resort where a 17 year old was trying to throw a snowball at his friends in the lift chair in front of him when he lost his balance.  He was able to hang on for a short time, but eventually fell over 45 feet to the ground.  Luckily, he is ok.

He suffered a collapsed lung, skull fracture, concussion, and a lacerated liver.  Surprisingly none of this required surgery and he has recovered.  Yikes!  Read the whole story at Grindtv.com
