You're laying out, watching the planes fly over you... seems [mostly] safe... then one literally misses you by just a couple inches. Had you ate the other 6 inches of your sub, you'd be a goner.
Like... WHAT!!!!!! Dude apparently looked up right before and "pancaked" himself to the ground.
I'm gonna go ahead and say you shouldn't be laying that close to a runway, but to each their own the saying goes.
