On 7 January 2023, a fully secured passenger on a Boeing 737-800 close to a convective cloud it was about to enter was forced against a seat arm rest during a momentary encounter with strong turbulence. Although feeling pain, the passenger did not consider it significant. But when the pain continued, they sought a medical assessment, which found two broken lower ribs and attributed this injury to a change in lateral acceleration due to translational movement and yawing of the aircraft.
