Last year was one of the safest ever for commercial aviation, according to data from the Aviation Safety Network. However, 2018 was worse than the five-year average because of several high-profile accidents. The network recorded 15 fatal airline accidents in 2018, resulting in 556 fatalities, making the year the third safest ever by the number of fatal accidents and the ninth safest in terms of fatalities. The safest year in aviation history was 2017, with 10 accidents and 44 lives lost. Twelve accidents last year involved passenger flights; three were cargo flights. Given the estimated worldwide air traffic of about 37,800,000 flights, the accident rate is one fatal accident per 2,520,000 flights. Harro Ranter, CEO of the network, said that the level of safety has increased significantly in recent decades. If the accident rate had remained the same as 10 years ago, he said, there would have been 39 fatal accidents last year. At the accident rate of the year 2000, there would have been 64 fatal accidents.
