Deadliest crash

1985 remains one of the deadliest years in aviation history. The deadliest of this year was Japan Airlines Flight 123, a Boeing 747 which crashed in mountainous terrain in Gunma prefecture, Japan, on 12 August, killing 520 of the 524 people on board; the accident was the deadliest of the 1980s decade, and remains the deadliest single-aircraft accident in aviation history. The second deadliest of the 1980s took place only weeks before, when Air India Flight 182, also a Boeing 747, was destroyed by a terrorist bomb over the Atlantic Ocean west of Ireland on 23 June, killing all 329 people on board. August 1985 remains the worst single month for commercial aviation fatalities in history. Largely accounting for Flights 123, 182 and the 12 December crash of Arrow Air Flight 1285R (256 fatalities), a total of 2,010 people were killed in commercial aviation accidents in 1985; the second highest in commercial aviation history since 1942; only 1972 had more fatalities (2,373).
