Deadliest occurrences
Not a complete record. A partial collection of documented occurrences: counts, not rates, and no measure of aviation risk. Coverage
42 of 183,362 records: 1 more filter. · Show all 183,362
The same occurrences rank differently depending on who is counted. These tables count, in turn, the people on board, everyone the occurrence killed, occurrences with more than one aircraft, and the injured.
Deadliest for the people on board
Fatalities are deaths among passengers and crew; the total adds anyone killed on the ground. Fatalities use each record's event total where one exists, otherwise the fatal injuries in the NTSB record.
| Occurrence | Date | Fatalities | Total fatalities | Location |
|---|---|---|---|---|
| SEA00FA080 · Piper PA-32-300 | 29 Apr 2000 | 2 | 2 | FORT SMITH, MT, United States |

None among the occurrences shown.
Most injured, whether or not anyone died
Injuries are the total the record shows: a Wikipedia record's infobox total, otherwise the serious and minor injuries in the NTSB record. People hurt on the ground are counted too, so a row can show hundreds injured although no one on board survived: all 106 injured at the Pentagon on 11 September 2001 were in the building.
