I just came across some more clips. Folks will do things they don't properly understand and will suffer nasty consequences at times as a result.

A potentially bad one over snow, another case of lockout on Facebook at the link above. They guy on the snowmobile knows where the gas is but that seems to be about it. An easy fatality but the guy hit some deep powder it seems, a good thing.
GRAPHIC, disturbing imagery - A bad one with injuries during a stunt staged for a crowd. No helmet and no real idea how to approach a launch like this.
Looks like a downwind launch in strong wind. The guys at the boat spent most of the time trying to figure out how to cleat a line, not good.
I hope the guy lived and recovered as fully as can be hoped for.
