The Bureau of Aircraft Accidents Archives (B3A),[54] a non-government organization based in Geneva, compiles statistics on aviation accidents of aircraft capable of carrying more than six passengers, excluding helicopters, balloons, and combat aircraft. Note that ACRO only considers crashes in which the aircraft has suffered such damage that it is removed from service, which will further reduce the statistics for incidents and fatalities compared to some other data. The total fatalities due to aviation accidents since 1970 is 83,772.
