An air crash is probably the worst among all kinds of accidents with serious consequences.
Geneva-based Aircraft Crashes Record Office (ACRO) compiles statistics on aviation accidents of aircraft capable of carrying more than six passengers, not including helicopters, balloons, or fighter airplanes. The ACRO announced that the year 2007 was the safest year in aviation since 1963 in terms of number of accidents. The year with most fatalities was 1972, with 3,214 deaths.
