This paper indicates that U.S. jet flights which recently suffered major crashes, averaged nearly twice as many passengers on board as U.S. jet flights that were uneventful. This statistically-significant excess results from two phenomena: a strong association between load factor (percentage of seats occupied) and the risk of a major crash; and, an over-representation of widebody jets among ill-fated aircraft. The authors define a crash as major if it results in the death of at least 20 percent of the passengers on board. In practice, the dichotomy "above/below 20 percent" partitions crashes into two vastly different clusters; the former generally entail low survival rates and the heavy loss of life, while the latter usually involve three or fewer fatalities.
