1/2560000 in 2016 VS. ? in history
In the past 70 years, Airplane has been an important tool for people to travel long distances. According to IATA annual report In 2016, the major aviation accident rate was 0.39, which was equivalent to only one major accident happen in every 2.56 million flights. This seemingly safe number is built on countless blood and sweat. Step down and turn back a little bit, let’s count the successes and failures in the flying history.

History of airplane accidents
Count of accidents by Year
Form the picture, we can see the total accidents trend from low to high before the 1970s. After that, there are some small peaks around 1990 and 2010. But the overall trend after 1990 is gradually going down.
At the beginning of 20 centuries, 1903, Wright brothers invented plane. In 1909, French hold a big flight competition, which threatened the England and other European countries. Even there were many problems with the current planes, the military can’t wait for using it in war. The first time of airplanes’ appearing thus was in Italo-Turkish War. The power of airplane attracted other countries’ military, which leads a huge development in the military aviation industry. From 1914, the first world wartime, airplane mainly used for investigating, transporting, and some peripheral things. At the time of world war II, which is around 1940. Airplanes had widely used in battle. At the same time, World civil aviation organization (IATA) established in Havana, the capital of Cuba in 1945. In 1978, Cater, the president of the USA, signed meaningful a law in the history of American aviation legislation, which is <the airline deregulation act>. The establishment and merger of companies in the US domestic aviation industry, route selection, fare establishment, and even loss-making operations, are basically out of government control and intervention. The number of airplanes grows up fast with the high possibility of air crash occurred. The other reason we consider is that airplane technologies that at that time had weakness and need to improve. With the technologies completed, the amount of air crash will decrease. These situations are obvious after 2000.
