    The vapors of hexane are highly explosive. There have been several industrial accidents caused by them.

    All they had to do was to have the tanks leak a small amount to build up vapors in the back of the truck. Then trigger a small ignition source to ignite them.

    This would cause the initial blast and light all the liquid on fire. The high heat generated by the fire damaged the bridge further.

      It’s like gasoline, basically. Actually, there’s a lot of it in gasoline. The thing is it’s tricky getting just the right fuel-air mix for something like that to blow up. I wonder if there was additional high explosive inside to disperse it first.
