"this result was so unexpected and bizarre that the pair concluded they must have made a calculation error and decided not to report the details of the incident

  In his (also excellent) article about the AF447 crash, the same author explains that the stall warning on the Airbus 330 went off when airspeed dropped below 60kt, because such a speed was considered impossible in flight. This is believed to have been a contributing factor to the confusion of the pilot flying: the more he pitched up, the more he stalled (as would be expected)... yet it made the warning go off. It's only natural to shy away from outlier values. I think the reason is that we want to place any input into a system, and outlier values don't fit, so we simply ignore them. It takes a special mindset to focus on outliers or even to accept them.
