so how far was the fall? is that the right way to ask that question? anyway--did he fall 10 feet? does not seem that high... or is the tower 20 feet from the top of the roof? still, if he landed on the top roof, that is still 10 feet... i guess he could die falling one story, but i am curious...
As someone who’s done a fair amount of climbing and had several falls, you don’t have to fall very far to suffer serious injury. A 10’ fall onto your head is plenty to kill you from head trauma or a broken neck.
In fact, my uncle died 40 years from about a 10’ fall off a scaffold onto his head.
OTOH, a friend of mine was helping move a sheet of plywood on a fourth-story roof and backed off the edge. Landed on his feet. Broke a bunch of bones but eventually (mostly) recovered.
Gravity sucks.
