The Worst Turbulence Incidents in History
23 cases from 1963 to 2026 · every fact sourced to the investigation report where one exists · Updated October 25, 2026
Turbulence almost never brings down an airliner today, but it is the most common cause of injuries on board. Below are the deadliest and most violent cases we could verify, with the official findings, the real injury counts (which often differ from the first headlines) and video from news crews where it exists. At the end, we compare each case with our own route data: the worst incidents come in two kinds, and only one of them shows up in seasonal data.

When turbulence brought airliners down
Five fatal accidents from the 1960s, most of which began with a decision to fly into a storm or close to mountains, and a 1993 case where turbulence tore an engine off a 747.
1BOAC Flight 911
- Date
- 5 March 1966
- Aircraft
- Boeing 707-436 (G-APFE)
- Route
- Tokyo Haneda → Hong Kong
- Deaths
- 124
- Injuries
- No survivors
- Turbulence type
- Mountain wave
Minutes after take-off, the crew made a visual climb past Mount Fuji on a clear, windy afternoon. Over Gotemba, at about 4,900 m (16,000 ft), the 707 broke apart in the air; the wreckage fell across the mountain's lower slopes. All 113 passengers and 11 crew were killed. It remains the deadliest turbulence accident in commercial aviation.
The aircraft “suddenly encountered abnormally severe turbulence over Gotemba City which imposed a gust load considerably in excess of the design limit.”Japanese Ministry of Transport investigation report, 1967

- Anchorage → Iliamna, Alaska
- Deaths
- 39
- Injuries
- No survivors
- Turbulence type
- Severe turbulence in clear air
On approach to Iliamna in clear weather and high winds, the turboprop met severe-to-extreme turbulence that nobody had forecast. The right wing, already weakened by fatigue cracks, failed. All 36 passengers and 3 crew died, and the FAA ordered inspections of the F-27 fleet.
“An in-flight structural failure caused by an encounter with severe-to-extreme turbulence. This turbulence was not forecast and its presence was not known to the flightcrew.”NTSB, AAR-70-16

6Japan Air Lines Cargo Flight 46E
- Date
- 31 March 1993
- Aircraft
- Boeing 747-121 freighter (N473EV, operated by Evergreen)
- Route
- Anchorage → Chicago
- Deaths
- 0
- Injuries
- None
- Turbulence type
- Low-level mountain turbulence
At about 2,000 ft after take-off from Anchorage, severe turbulence rolled the freighter 50° to the left and tore the No. 2 engine and its pylon clean off the wing. The five people on board were unhurt and the crew landed back at Anchorage. It is a rare modern case of turbulence causing structural damage, helped by a fatigue crack in the pylon.
Separation of the No. 2 engine pylon “due to an encounter with severe or possibly extreme turbulence that resulted in dynamic multi-axis lateral loadings that exceeded the ultimate lateral load-carrying capability of the pylon”, which was already weakened by a fatigue crack.NTSB, AAR-93/06

1Singapore Airlines SQ321
- Date
- 21 May 2024
- Aircraft
- Boeing 777-300ER (9V-SWM)
- Route
- London → Singapore, diverted to Bangkok
- Deaths
- 1
- Injuries
- 56 serious, 23 minor
- Turbulence type
- Convective (fast-growing storm cloud)
Cruising at 37,000 ft over southwest Myanmar, the 777 flew into air above a rapidly growing storm cloud. In 0.6 seconds the vertical load swung from +1.35 g to −1.5 g, throwing unbelted passengers and crew into the ceiling; the aircraft dropped about 219 ft in roughly five seconds. A 73-year-old British passenger died; a UK inquest in September 2026 concluded that the physiological effect of the turbulence brought on his cardiac arrest. The seat-belt sign had been switched on eight seconds before the drop.
The encounter “was likely the result of this rapidly growing cloud”, which rose from about 27,500 ft to 40,000 ft in ten minutes. Whether the weather radar failed to show it “cannot be ruled out”.Singapore TSIB final report, May 2026

- Route
- Tokyo Narita → Honolulu, returned to Tokyo
- Deaths
- 1
- Injuries
- 18 serious, 171 minor
- Turbulence type
- Clear-air turbulence (jet stream)
About 870 nm out of Narita at 31,000 ft, the 747 hit clear-air turbulence near the jet stream. The recorders showed +1.8 g followed by −0.8 g six seconds later; contrary to early press reports of a 1,000 ft plunge, altitude changed by less than 100 ft. A 32-year-old passenger who was not wearing her seat belt died. According to the NTSB, it is still the last fatal turbulence accident on a US airline.
“The pilot-in-command's inadvertent flight into adverse weather conditions, and the difficulty of obtaining adequate weather forecasts of over-ocean turbulence. Factors contributing to the accident include the presence of clear air turbulence, and the failure of the flight attendant to issue a safety advisory.”NTSB, DCA98MA015

What our data shows: two kinds of worst-case turbulence
We ran each incident route through the same model we used for our ranking of the most turbulent flight routes: a full year (2025) of NOAA upper-air winds, with the wind-shear formula our app uses to forecast clear-air turbulence at cruise altitude. For each route we compared the month of the incident with the route's yearly average. This is the typical climate of that route and month, not the weather on the day.
Clear-air cases tend to fall in the route's roughest season. In 3 of the 5 cases where investigators or the airline pointed to clear-air or unforecast turbulence, rough-air conditions in that month were well above the route's average: United 826 flew Tokyo–Honolulu in December, when the jet stream over Japan is at its strongest.
| Flight | Route | Month | That month | Year avg |
|---|
| United 826NTSB: clear-air turbulence | NRT–HNL | December | 14.6% | 5.8% |
| United 1890NTSB: unanticipated, no storm | LAX–EWR | February | 14.6% | 5.4% |
| Lufthansa 469 (2023)Lufthansa: clear-air turbulence | AUS–FRA | March | 11.3% | 5.1% |
| United 897 (2010)NTSB: clear-air turbulence | IAD–NRT | February | 3.6% | 3.5% |
| Aeroflot 270 (2017)Russian regulator: unforecast CAT | SVO–BKK | May | 0.9% | 2.8% |
Storm cases do not. In 7 of the 9 convective cases, the month was calmer than average for clear-air turbulence. These aircraft were hurt by fast-growing storm clouds, which can appear on any route in any season and are only visible on radar, satellite and pilot reports in real time.
| Flight | Route | Month | That month | Year avg |
|---|
| Singapore SQ321 | LHR–SIN | May | 1.2% | 2.1% |
| Emirates EK421 | PER–DXB | December | 0.6% | 1.7% |
| Etihad EY474 | AUH–CGK | May | 0.6% | 0.8% |
| SpiceJet SG945 | BOM–RDP | May | 0.0% | 3.6% |
| Avianca AV18 | BOG–BCN | June | 0.0% | 1.2% |
| Delta DL175 | MXP–ATL | August | 2.7% | 5.3% |
| Delta DL56 | SLC–AMS | July | 0.8% | 2.6% |
| Condor DE2314 | FRA–MRU | March | 4.3% | 2.1% |
| Hawaiian HA35 | PHX–HNL | December | 4.4% | 3.1% |
The pattern is not perfect: Aeroflot 270 met clear-air turbulence over Thailand in May, which a 2.5° climate grid rates as calm, and Hawaiian 35 and Condor 2314 hit storms in months that were also rough for clear-air turbulence. But the lesson holds. Seasonal data tells you when a route is usually bumpy; only a live forecast, storm data and pilot reports tell you about the cloud that is growing in front of you today.
Turbulence in numbers
- Most common accident type. 111 of 295 accidents on US airlines in 2009–2018 (37.6%) were turbulence-related, and every one of them involved at least one serious injury. None caused substantial damage to the aircraft. (NTSB SS-21-01)
- Crew get hurt most. Flight attendants were 78.9% of the seriously injured; of 123 seriously injured people, one was documented as wearing a seat belt. About half of these accidents happened during descent and approach. (NTSB)
- A record year in 2024. The FAA counted 207 serious turbulence injuries on US airlines in 2009–2024, 80% of them crew; 2024 was the worst year, with 23. (FAA)
- Getting rougher up high. Severe clear-air turbulence over the North Atlantic rose 55%, from 17.7 to 27.4 hours a year at an average point, between 1979 and 2020. (Prosser et al., 2023) A 2026 study projects a further 10–50% increase in severe turbulence by the end of the century, depending on region and emissions. (de Medeiros & Williams, 2026) Not every region shows a clear trend yet: over the North Atlantic and North Pacific, natural swings still mask the warming signal. (Foudad et al., 2024)
- More sharing. Over 3,300 aircraft from 31 airlines now send automatic turbulence reports to IATA's Turbulence Aware platform. (IATA, April 2026)

What changed after SQ321
- Singapore Airlines stopped serving hot drinks and meals while the seat-belt sign is on. Normal service returned in August 2024, but hot drinks, including soup, are still not served when the sign is on.
- Korean Air stopped serving instant noodles in economy class from 15 August 2024, citing a sharp rise in turbulence, and now ends cabin service earlier before landing.
- Southwest Airlines moved cabin preparation for landing from 10,000 ft to 18,000 ft from December 2024 to cut turbulence injuries.
- Investigators in Singapore recommended that ICAO require weather-radar recording on older large aircraft, because they could not tell whether SQ321's radar had shown the storm.
Frequently Asked Questions
What is the worst turbulence incident in history?
The deadliest is BOAC Flight 911 on 5 March 1966: a Boeing 707 broke apart in severe mountain-wave turbulence near Mount Fuji, killing all 124 people on board. In the jet age, the worst for injuries is Singapore Airlines SQ321 on 21 May 2024: one passenger died and 79 people were injured, 56 of them seriously.
Has turbulence ever caused a plane crash?
Yes, but it is now extremely rare. Every airliner loss caused by turbulence in this list happened in the 1960s, usually after the crew flew into thunderstorms or near mountains. Since then, stronger certification rules, weather radar and storm avoidance have made a turbulence crash extremely rare. Today the danger is injuries to people who are not wearing a seat belt.
When did turbulence last kill an airline passenger?
A passenger on Singapore Airlines SQ321 died on 21 May 2024; a UK inquest concluded the turbulence brought on his cardiac arrest. A SpiceJet passenger injured in turbulence on 1 May 2022 died of his injuries months later. Before that, the last turbulence death on a US airline was on United Flight 826 in December 1997.
Who gets hurt in turbulence?
Mostly flight attendants. In the NTSB's study of US airline turbulence accidents from 2009 to 2018, flight attendants were 78.9% of the seriously injured. Of 123 seriously injured people, only one was documented as wearing a seat belt.
Is turbulence getting worse?
Clear-air turbulence appears to be increasing. A University of Reading study found that severe clear-air turbulence over the North Atlantic rose 55% between 1979 and 2020, and climate models project further increases. Other research finds the trend is clearest over East Asia, North Africa and the Middle East, and harder to separate from natural variability over the oceans.
How can I stay safe in turbulence?
Keep your seat belt fastened whenever you are seated, not only when the sign is on. In almost every serious case in this list, the people who were badly hurt were out of their seats or unbelted.
