There were only eight accidental airline crashes last year accounting for 161 passenger and crew deaths -- the fewest crashes and deaths since at least 1946.
The tally by Flightglobal, an aviation news and industry data company, excludes a German airliner that was deliberately flown into a mountainside in the French Alps last March, and a Russian airliner packed with tourist that exploded over Egypt in October. The toll for those two incidents was 374 killed.
"In recent years, airline safety has improved very considerably to the point where, typically, there are now very few fatal accidents and fatalities in a year," said Paul Hayes, Flightglobal's director of air safety and insurance.
"However, flight security remains a concern."

Although some years are better than others, the fatal accident rate has been improving for many years. The global fatal accident rate for all types of airline operations in 2015 was one per 5 million flights, the best year ever.
Those tallies are for all types of airline flights, including cargo, positioning, training, and maintenance flights. There were just 98 paying passengers killed last year in accidental crashes compared to 790 in 2007. A far cry from the 1970s, when the annual average of passengers killed in accidental crashes was 1,289.
A big reason for the improving record is better engineering: Today's airliners and aircraft engines are far safer than earlier generations of planes. They are more highly automated, which has reduced many common pilot errors.
The aircraft improvements are due primarily to lessons learned from crash investigations that are taken into account when new planes are designed, said John Goglia, a former US National Transportation Safety Board member.
As older planes are replaced with newer planes, aviation becomes safer, he said.
