Horror story from Naval Submarine School while I was an instructor.
A student from another code had gone out and bought his first bike.....a shiny, brand new Suzuki GSXR-1000. For his first bike. Yep.
The weekend after he buys it he has duty on Sunday. Doesn't show for muster. Marked as UA (unauthorized absence). Monday rolls on, still doesnt show for muster. Tuesday....same thing. Students normally go UA for a couple of days then end up in the crapper when they come back as we in the military don't take too kindly to people just decideing to go off for a bender.
Except he didn't go off for a bender. He had left base on the Saturday for a ride on his new bike. He made it about a mile and a hlaf off base, along a costal road, going WAY too fast and went off on a corner. Sailed through the air....over the railroad track, obviously hit a couple of trees. Bike found in the Thames river, just by the shore, and he was found mangled. Took a few days to find him as he was at least half a mile from the nearest building.
It was actually a train driver who spotted articles of clothing hanging from a tree and had the maintenance team check it out.
Another less deadly and slightly upbeat story was a student who bought himself a Buell and crashed it leaving the dealership. He didn't even have a learners permit!!! But why would a dealership let something like a valid license stand in the way of a sale right? (The kid had the very basics down and decided to give it some leaving the dealership. Didn't expect the power and ended up ploughing it into a railing. The only damage was to his bike and his pride.
