Commercial airliners had their safest year ever. There were no fatalities on commercial passenger jets in 2017, according to two groups that track airplane crash data, making it the safest year in modern aviation history. There were two fatal accidents in passenger airliners involving small turbo-prop planes, according to To70, a Dutch aviation consulting firm. These numbers mean that the rate of fatal accidents in commercial flights in large airplanes is one per 16 million flights, according to To70.
