Man flies off Gatlinlburg Mountain Coaster!!

A rider was thrown off of a rollercoaster in Gatlinburg!! The coaster is the Gatlinburg Mountain Coaster and the man was thrown 10 feet from the track as the coaster entered a curve. He suffered serious injuries to his head, wrist and ankle. The ride was shut down while authorities investigated but it was deemed to be safe. So the only thing I can think of is that maybe he wasn't buckled in correctly or unbuckled??? That's so scary! As I was screaming down those mountains last week, I definitely considered, "what would happen if I fell off"... I didn't really think I would but dang!
