A tour bus with elderly people ran off the mountain here years back,they think the driver went to sleep.A friend worked the accident and said for years he had nightmares.Another person I know had their dog bring a human hand from the accident into the yard,I think most of them died.My heart goes out to the victims,their families and the people that work the accident scene.
I just checked on this and it was a combo of driver fatigue and faulty brakes,there were some survivors which is amazing since the bus went about 200 feet down a steep rocky ravine.
