Fluid inertia at it's most dangerous. How ling was the tarmac shut down?If you zoom in, you can see the tanker on its side. The speed limit on the vehicle service road is 15mph. From what I was told, the operator was driving on the wrong side of the road and then had to swerve right to avoid a vehicle coming his way and then swerved left to make a turn in the road and the sloshing of the fuel cause the tanker to flip over.
