In cases where planes or trains crash, the vehicles are running at 61% capacity, as regards passenger loads. In cases where they don’t, the vehicles are running at 76% capacity. That’s a difference of 15% over a large computer run, and that sort of across-the-board deviation is significant. Staunton points out that, statistically speaking, a 3% deviation would be food for thought, and he’s right. It’s an anomaly the size of Texas.
