The last big multi wheel drive fire tender I was stood against was literally built like a tank with armoured glass and big roll bars all around the cab front and side area, could the driver not have rammed it hard to break the blades off, I know spinning blade have huge inertia with them, but could that sort of attack/rescue have worked. or is it fear of the unknown that would have held people back..
But what a very sad outcome, simply though missing the dolly. poor chaps!,
