'>It was such a spectacular wreck it made all three of the major networks' evening newscasts: That semi plowing into a concrete barrier in Kansas City, Kansas, on Wednesday, tearing apart the tractor whose fuel ignited shortly after impact.
Incredibly, the driver suffered only minor injuries. He and his dog were pulled from the wreckage by motorists. Authorities think he may have suffered a “medical emergency” and perhaps passed out, which is why he veered out of the travel lane.
CBS and NBC carried video from a surveillance camera that shows the rig drifting off the outside lane and hitting the massive concrete structure. Footage shot from the ground shows the tractor, twisted nearly 90 degrees and its hood missing, with a stream of fire engulfing much of the tractor's rear.
ABC News' anchor, David Muir, called it a “tanker explosion” as he read the introduction to the video, but the trailer was an empty lowboy. Why did he, or whoever wrote the script, think it was a tanker? No doubt because of the fire, evidently fed by diesel fuel from one or more of the tractor's saddle tanks. You can see fuel spewing upward in a yellow cloud as the tractor hits the concrete.
Saddle tanks will burst in impacts, and are often torn open if a truck just runs off a road and into a ditch. The result of ditching is an expensive hazmat cleanup, if not a fire.
Why aren't fuel tanks made to survive at least the ditch accidents? Because they'd be more expensive and weigh more, and this is something rarely discussed at industry meetings. When I ask fleet managers
