kdub– People get killed every year around here from idiots shooting guns in the air on New Year’s eve. Mythbusters was testing a different theory, that a bullet fired straight up will come straight down. In a vacuum it would.
When I was a kid, I shot a bb gun straight up in the air to hear them hit in the ground around me. I realized my stupidity when a bb embedded itself in the top of the picnic table next to my elbow.
