Interesting. Weapons guys have told me that it is SOP to move aircraft to a secure area built contain an accidental discharge.
That is the practice but apparently this guy was working on it alone - violation - and was using a quick-fix tool, and the jet was pointed the right direction. The round hit the shack on the other side of the base. When it happened they found out the backstop and the wall of steel and dirt in front had eroded. All it takes is a small gap and its off to the races. We were all briefed if he used the correct tool he would not have shifted the nose of the jet and the safety wall would have worked.
