Structure fires are never a good thing, but that doesn't mean they can't be impressive. Last Sunday, this railroad trestle in Texas caught fire, and when authorities decided it would be too dangerous to fight, they just let it burn.
The result is a spectacular show of what have to be some of the most dangerous dominoes in the world.
The unintentional fire-show ultimately cost about $US10 million in damages, and while the resulting footage probably isn't worth quite that much, it's something to see. Especially the way the rails themselves fall like puny little wires. Fortunately, the fire was contained to just the bridge, and no one was injured in the process. As far as disasters go, this is a fun one to watch, and it's relatively guilt-free. [KWTX via Reddit]
