So I used to work on those train tankers. I can tell you that story is complete bullshit. The amount of anti fire and safety measures are nothing to laugh at. We used to wrap them in 2-3 layers of fire proof blankets and anti fire and anti spark paint and so much more. Those tankers are built not to explode. This is part of the movie. Maybe scare event?
Did you hear the guy Tucker interviewed tonight? He had a very different take. His was - that all normal safety maneuvers/measures were deliberately ignored and the resultant catastrophe.
