An unfortunate turn of events for somebody who makes her living on her back.
She’s lucky it was only a broken back. We had one of those indoor trampoline places in my city and a guy did a flip into a foam “pit” (it was actually an entire floor of trampolines with a layer of foam cubes on top. He landed in between two trampolines that had some sort of padded divider between them, broke his neck and died. Kids were jumping all around this dead guy for a few minutes before someone realized something was wrong.
