Flying on a commercial jetliner has never been safer.
It will be four years on Tuesday since the last fatal crash in the United States, a record unmatched since propeller planes gave way to the jet age more than half a century ago. Globally, last year was the safest since 1945, with 23 deadly accidents and 475 fatalities, according to the Aviation Safety Network, an accident researcher. That was less than half the 1,147 deaths, in 42 crashes, in 2000.
In the last five years, the death risk for passengers in the United States has been one in 45 million flights, according to Arnold Barnett, a professor of statistics at M.I.T. In other words, flying has become so reliable that a traveler could fly every day for an average of 123,000 years before being in a fatal crash, he said.
