From the Wikipedia article

Continental Airlines Flight 128, operated by a Boeing 767-200ER, registration N76156, is a commercial flight between the city of Rio de Janeiro, Brazil, and Houston, United States. It became known after it diverted to Miami International Airport on 3 August 2009, after encountering severe turbulence en route. The aircraft was flying over the region between Puerto Rico and the Turks and Caicos Islands, about 50 miles north of the Dominican Republic.

At least 26 people on board were injured, four of them in more serious condition.

According to Kathleen Bergen, spokeswoman for the FAA, the US civil aviation agency, said that the aircraft landed in Miami at around 5:30 local time (6:30 Brasília time), about an hour after passing through the zone of turbulence.

According to the airline, at the time of the turbulence the "fasten seat belts" signs were illuminated, but many passengers were not wearing their seat belts, causing them to be thrown against the ceiling. The official cause of this incident is still under investigation.

NTSB narrative

The Captain stated that the ride had been smooth at their cruise altitude of 36,000 feet and he was able to see lights on the ground below with good forward visibility as well. The autopilot was engaged, both weather radar devices were on and functioning normally, and the seat belt sign was illuminated. Seconds after he initiated a climb to 38,000 feet, the aircraft encountered an initial severe bump followed by a few seconds of moderate turbulence and a final severe bump within the span of about ten seconds. The aircraft continued to climb and level off at 38,000 feet.

The Captain was notified that there were some passenger and flight attendant injuries and made the decision to declare a medical emergency diversion to Miami International Airport in Florida where the aircraft landed one hour and forty minutes later.

The FDR data indicated that, upon a climb from 36,000 feet to 38,000 feet, the vertical acceleration changed from 1.0 g’s to 2.0 g’s in one second, continued to oscillate from 2.0 g’s to 0.9’s for seven seconds before returning to 1.0 g’s and then immediately accelerating to -1.0 g’s in 0.5 seconds. No pilot reports near the location and close to the time of the turbulence encounter were found on record, and the weather document issued for the incident flight showed no predicted turbulence activity at the time of the turbulence event in the turbulence region. In addition, a meteorological study using satellite weather imagery at the time of the incident indicated the presence of isolated, rapidly developing cumulus congestus to cumulonimbus clouds under the airplane’s flight path.

Probable cause

The flight crew's inadvertent flight through the top of a convective updraft that resulted in an encounter with convective induced turbulence. Contributing to the severity of the incident was the unrestrained status of several passengers, contrary to the lighted seat belt sign.
