Heart breaking video.
RIP. .
TOWTEAMBASE: The live leak link is posted at R & N. I watched the whole 3 minutes. At time 1:14-1:15 we hear the observer's first words: "Oh, f___!" There's an understatement.
I am guessing the observer is someone on perimeter security patrol, or some such, as there was sound of a canine in the cab. It looks from that clip that the wind was blowing away from the fuel trucks parked near the perimeter.
