Month wise analysis of the Air Crash data between 1908-2009 represented by this treemap reveals that the number of fatalities were highest in November and lowest in May.
The number of accidents spikes in 1972 and 1983, with almost 65 crashes. There is an overall increase after 1950 attributing to development of the aviation industry and decrease after 1990 possibly due to safer protocols.
Aircraft manufacturers like Boeing, Antonov and Airbus have had significant fatalities during the 2000s and fall within the first 10 when it comes to fatalities.
Aircraft models from Boeing like B-747-121 and 122, Lockheed L 1011 and Airbus A30 appear to be safer models having higher number of survivors after the aircrash. However, other factors like crash intensity determine the fatalities.
In most cases, the aircrashes only have onboard fatalities and none on ground. However, the datapoint to the extreme right indicates a higher onground fatality than onboard, representing the 9/11 Attack on the World Trade Center, New York.
The distribution of air crash locations are concentrated in North America and Europe, possibly due to factors like, erratic weather, involvement in the world war and increased air traffic due to economic development.
Air crashes during the world war between 1914 and 1945 show various locations especially concentrated around the US and Europe depicting their active involvement and a few in their African and Asian colonies.
Between 2000 and 2009 the United States of America has had the largest number of air accidents than any other country. This may be due to an increase in air traffic as a result of economic development and more domestic flights operating within the country.
The disastrousness of a crash is measured as the sum of onboard and onground fatalities. As of 2009, the 9/11 attack on the Twin Towers, New York is the most disastrous in history with 5663 people being killed.
China Airlines is the worst airliner with 225 fatalities followed by Air France with 109 fatalities. The Russian Military has had several flight crashes and stands second overall when it comes to operators.
Aeroflot is the worst airliner in history, followed by Air France and American Airlines. Indian Airlines with 859 fatalities falls within the worst 5. The US Military is the second worst overall after losing multiple personnel in various crashes.
When it comes to survivors onboard, Aeroflot, Pan America World Airways and Air France top other operators with more than a thousand survivors from multiple crashes. However, this standalone report cannot conclude on the safety of these airlines.
