Despite all the exploding hoverboards, smoking laptop batteries, and inescapable in-flight performances, a new report finds that 2017 was the safest year ever for commercial air travel. There were no passenger jet crashes anywhere in the world, according to separate reports by Dutch consultancy To70, and The Aviation Safety Network found, compared to 2016, there were 71 civil aviation accidents, six of which were fatal. However, as the BBC notes, their report only includes large passenger jets, not smaller passenger planes, so those crashes were not included in the tally.

Cargo jets weren’t quite so lucky. The Airline Safety Network reports that there were a total of 10 fatal accidents involving cargo jets, resulting in 79 deaths. That’s compared with 16 accidents and 303 lives lost in 2016.

According to To70’s calculations, that’s a rate of one deadly accident for every 16 million flights, making 2017 the safest year in aviation history–and making air travel the safest means of transport, said To70 researcher Adrian Young, even as worldwide air traffic grew by 3% in 2017 over 2016.

Still, even as it credited advances in global air safety, To70 warned that airlines must stay vigilant, particularly in light of the human element (specifically pilot fatigue and mental health concerns). The researchers noted nonfatal accidents like the Air France flight that had to make an emergency landing in Newfoundland, Canada, in September when its engines failed.
