The paper presents safety data for the period 1977--86 from more than 30 U.S. domestic airlines and 80 international flag carriers. These statistics are examined in conjunction with others from an earlier MIT study about the previous two decades. The primary safety measure used is "death risk...

Through the analysis of CAB market-share data, an attempt is made to estimate the extent to which fears arising from the Chicago DC-10 crash displaced passenger traffic onto other kinds of aircraft. Factors that could distort simple "before-after" comparisons are discussed and a procedure to...

Within the First World, observed differences across air carriers in passenger death risk are almost never statistically significant. But given the rarity of fatal crashes, even a lopsided split of crashes across airlines is unlikely to achieve significance. For greater perspective about relative...

We consider the fatal accident records of 58 major world airlines, and in particular try to compare appropriately the safety records of airlines whose route structures overlap and which thus compete for passengers. We separately review data about the 18 principal U.S. domestic airlines and 40...

Airport capacity could increase if, even during inclement weather, independent landings could occur on parallel runways only about half a mile apart. A key question about such operations is whether the collision risk they entail is acceptably low. Pursuing that issue, we explore a method for...
