I know it's still not a great shot, but when you realize the lights are on 220/581 - and the little red glow to the left there is the fire - that will give you an idea as to how high the flames were at that moment. Then imagine them 6 times higher, which is how high they were in the fireball shots below.
And those flames were originating roughly 30-60 feet below the roadway.
8600 gallons of fuel, and all that you see burning here are the pressure relief valves and the twin 125 gallon tanks the truck has.
See you in the morning, when the smoke will still be drifting off into the sky.
