Airline travel is safer than ever. Given the large number of people who fly each year—some four billion passengers in 2017 compared to about 1.5 billion 20 years ago—the risk of any single person dying in a commercial air crash has fallen dramatically. And yet, when there’s a deadly accident, like today’s crash of Indonesian budget flight Lion Air JT610, it doesn’t feel that way. Flight JT610 crashed in the waters off Indonesian capital Jakarta less than 15 minutes after takeoff, with all 189 passengers and crew on board believed dead.
The last five years have been troubling ones for Asian passenger airlines, with a number of major deadly air crashes, including four in 2014 alone. Excluding military flights, and not counting smaller fatal accidents that took place over the period, these air disasters killed more than 1,000 people, including those on JT610. In some cases, the exact cause of the disaster will never be known.
