Well you did say "I'm a pilot"
Physics don't care what direction your body is going. Up, down, right, left. G loading is G loading. You clearly dont understand energy managment if your telling me a car crash and falling 8 feet off a ladder are simply due to the vertical or horizontal direction of the body.
So a piano falling straight down at 100MPH a bigger chance at killing me then a piano being shot at me vertically at the same speed while I'm walking down the street? Please, tell me more.
