2017 was the safest year in history for commercial airlines, according to industry research.

根据行业研究显示，2017年是商业航空历史上最安全的一年。

There were no passenger jets crashes anywhere in the world, separate reports by Dutch consultancy To70 and The Aviation Safety Network found.

荷兰咨询公司To70和航空安全网的两份报告显示，2017年世界各地没有发生重大客机坠毁事故。

But To70 warned that despite high safety levels on passenger planes, the "extraordinarily¹" low accident rate must be seen as "good fortune".

但To70警告称，尽管客机的安全水平提高，但必须把“极其”低的事故率看作是“运气好”。

A report by the Airline Safety Network said there were a total of ten fatal accidents, resulting in 79 deaths last year. That compared with 16 accidents and 303 lives lost in 2016.

航空安全网的一则报告指出，去年共发生了十起致命事故，造成79人死亡。相比之下，2016年发生了16起事故，303人丧生。

The organisation² based its figures on incidents involving civil aircraft certified³ to carry at least 14 people.

该组织得到的数据是基于那些涉及民用飞机的事故，这些民用飞机证实至少可以搭载14人。

The most serious accident of 2017 came in January when a Turkish cargo⁴ plane crashed into a village in Kyrgyzstan killing⁵ all four crew and 35 people on the ground.

2017年最严重的事故发生于1月份，一架土耳其货机坠毁在吉尔吉斯斯坦的一个村庄，造成四名机组人员和35名乘客当场死亡。

Neither report counted military or helicopter accidents, meaning the year's worst air disaster, the crash of a Burmese Y-8 military transporter plane, which crashed in June killing all 122 people on board did not appear in the statistics.

这两份报告均未把军事或直升机事故计算在内，这意味着今年最严重的空难数据没有统计在内。6月，一架缅甸Y-8军用运输机坠毁，机上122人全部遇难。

"Since 1997 the average number of airliner⁶ accidents has shown a steady and persistent⁷ decline, for a great deal thanks to the continuing safety-driven efforts by international aviation organisations such as ICAO, IATA, Flight Safety Foundation and the aviation industry," ASN president Harro Ranter said.

航空安全网总裁哈罗·兰特表示：“自1997年以来，飞机事故平均发生的数量持续稳步下降，这在很大程度上都要归功于国际民航组织、国际航空运输协会、飞行安全基金会和航空业等国际航空组织持续加强航空安全所做的努力。”
