Planes have been around for almost 120 years. It is not a surprise that as aviation has evolved, so too have trends in their crashes. There are also interesting trends within the 12 months of the year, as well as within only the 24 hours of the day.
(Note: 1920 includes all years previous, starting at 1908)
Insight: It takes until roughly after WWII (1945) for there to be large numbers of crashes in continents other than Europe and North America
Insight: Plane Crashes have dramatically decreased in the last 20 years, after almost 6 decades of a relatively constant level of crashes.
