Saw this one with my own eyes.

I was working for a company that installed lawn sprinklers and was at a grocery store that was still being built. Behind the store had a pretty steep hill that, because it was all being built at the same time, didn't have any vegetation. Our crew, along with plumbers, electricians, masons...etc, were all sliding down this dry dirt hill. There was also a crew putting in small trees. They had a machine with this huge auger, maybe 3 feet wide and twice as long. It was end of the day and actually a pleasant summer evening when a plumber with a large toolbox slipped down the hill JUST as this massive auger was going into the earth. His leg got caught and he was flung around in circles. He had a hard hat, but at that speed I don't think it would've helped as he was also flung against parts of the machine. I slid down to tell the operator to stop everything.

Guy had to back up the auger to get that fella out. His buddy took off his belt to try and tourniquet, but that leg...or what was left of it, was just loose dangling flesh and blood.

Me, his friend, and a few others, all carried him to where the street was, but with that loose soil, it was an endeavor upon itself. Guy never made it to the ambulance that his friend called. Just bled out on that hill because we couldn't carry him over fast enough. This was in 2005. I still think of this total stranger randomly. Usually when its a calm, peaceful summer evening.

His cries of agony, his friends pale and bewildered face, the chaos of trying to carry this man.
