Reminds me of Afghanistan Feb 2002, delta company (not delta force) guy was clearing his MK19 (full auto grenade launcher mounted on hummer), sent an HE round right over a running c-130 preparing for take off. It was a little sketchy, that dude did not enjoy the rest of his day. Luckily, Kandahar airfield was still just an airstrip and the round went sailing into the brown landscape.
