When I started a job rebuilding windmill transmissions, as my new boss walked out onto the shop floor with me, he gave a warning... "The stuff you'll be working with wont hurt you, it will kill you." A typical transmission weighed about 28 tons. Fun learning to handle them with cranes, but you always have to be aware of what's going on. It was a cool trick turning them over using 2 cranes. I do remember 2 accidents that would have killed anyone who was in the wrong place. A 28 ton gearbox doesn't need much speed to crush the snot out of you.
I know of a millwright working at TVA's Watts Bar Nuclear Plant that was crushed by the 600-ton Reactor Pressure Vessel When it drifted laterally. By the time he realized it was moving, he was already stuck between it and the containment wall. 600 tons does not yield to a mere human body. It might have been moving at 12" per minute, if that.
I'm scared of heights, but love a helicopter ride. Weird part is I think I am scared of stopping at the ground, because I'm OK above 200 feet. I don't have a problem rotating at V1. Cool as a cucumber with the engine spooled up and easing the yoke back. But, 12' up with a toe on the ladder.....
I need to talk someone into letting me fly their plane again. It's been a long time.
<edit> A preliminary investigation indicated that he tried to attack his son with a running chainsaw while his son mowed the yard. His son, who was not identified, ran over his father with the lawn mower as a way to defend himself, the press release stated.
