Here is a full size picture of "The Truck that went over the Edge!" courtesy of Paul James, USN.  I have also included a part of the note from Paul that accompanied the picture.

"I'm sending you a picture of the truck that rolled off the mountain. 
When you see it, I'm sure you will agree that if the driver didn't get
thrown out, he would not have survived the crash. I never did know who
was driving it. They may have been keeping it quiet."

Hope you enjoy the picture,
Paul

A later note received from another Seamen, Nick Tazza, helps identify at least one of the lucky people involved in this wreck.  Here is Nick's note.

"Mike Moyer was one of the guys that rolled the truck down the mountain. How they lived is beyond me....I remember they (especially Mike) took a horrible  ribbing after he came back to the site....I was one of the worst offenders...I did a few dedications out of the radio station on site, and I said, "This one is going out to Mike Moyer for when he takes a drive on the Mountain......then I would play "Fool on A Hill". by the Beatles.
