I had a similar, albeit less exciting, event a couple of weeks ago.
I was happily cross cutting some pieces of skirting on the table table, using the fence for my length guide (stop block) and I had run quite a few before i forgot to pull one back slightly from the fence before cutting...
As you can expect it got caught on the fence and succinctly got thrown out the back of the saw!!
Luckily because I always have the riving knife and guards in place, plus I pretty much never stand behind the cut, it missed me and fairly gently came to rest on the floor.
It did however remind me to maintain attention and stick to the best practices to avoid injury.
