High Quality Content by WIKIPEDIA articles! A total of 49 Boeing 747 aircraft, first flown commercially in 1970, have been involved in accidents and incidents resulting in the complete destruction of the aircraft or it being declared to be damaged beyond economical repair. Many of these losses have been due entirely to hostile actions, including terrorism. Of the 49 aircraft losses, 23 resulted in no loss of life, in one a hostage was murdered, and in another a terrorist died. Some of the aircraft declared damaged beyond economical repair were older 747s that sustained relatively minor damage that, had they been newer, would have resulted in their being repaired.
