Well...I'm guessing there will be a job opening for this guy. I'm willing to bet how this happened. Guy was probably the only one on the tarmac when he slipped into the cockpit of the plane. Decided to start jamming to "Highway to the Danger Zone" when he got a bit overwhelmed by the moment and then...BRRRRRRRRRT. Although, I'm wondering if the story is true, as I am unaware if an F-16 is capable of firing while grounded.
