Overview
- The AAIB report covers a 6 December 2024 Los Angeles–Heathrow flight that hit turbulence south of Greenland.
- The disturbance lasted about 10–15 seconds and was perceived by the captain as light to moderate.
- One passenger broke an ankle while returning from the toilet after missing the seatbelt sign, and a cabin crew member fractured an ankle while lowering into her jump seat.
- Shortly afterward, another passenger lost consciousness, with crew and two doctor‑passengers providing care and consulting MedLink for advice.
- The captain had illuminated the seatbelt sign in advance using live weather data, considered diversions to Gander or Keflavik, and continued to Heathrow where ambulances took three people to hospital.
