At least 37 people were injured aboard an Air Canada flight that had severe turbulence and had to make an emergency landing.
The plane, which carried 284 passengers and crew, was traveling from Vancouver to Sydney, but was diverted to Hawaii.
Thirty people were taken to the hospital in Honolulu on Thursday. Nine had serious injuries, officials say.
Air Canada said the Boeing 777-200 aircraft "encountered sudden turbulence in the clear air … two hours after Hawaii."
He added that he was organizing hotels in Honolulu until a new flight to Australia could be arranged.
The plane landed in Hawaii at 06:46 local time (16:46 GMT) on Thursday.
"We had turbulence and we all got to the roof, and everything fell … people flew out," said Jess Smith, a passenger aboard the flight, to the local KHON television station.

- Satellite to help airplanes avoid turbulence.
"Some people who were not tied saw them rise in the air and hit their heads on the roof and everything, so it was quite intense," another passenger told the station.
Alex Macdonald of Brisbane told Canadian broadcaster CBC News that passengers on board were "extremely shocked."
"I saw the people in front of me hit the overhead luggage compartments and then fall into their seats," he added.
Photographs taken inside the aircraft show that oxygen masks were thrown and service cars were thrown during the incident.
What is the turbulence of the outdoors?
CAT: turbulence in the clear air: it occurs in a calm and clear blue sky, without any visual indication like the clouds.
It occurs when air masses that move at different speeds meet and can not be identified with the naked eye or with conventional radar.
Pilots use reports from other aircraft, transmitted through air traffic control, to track CAT patches.
Passengers have reported that the cabin is bloody and dented by passengers hitting the roof of the aircraft.
A posting on a passenger's social networks showed him wearing a collar at the airport, along with the caption: "Unexpected vacation in Hawaii."
An Australian country band, Hurricane Fall, was also on the flight at that time.
They confirmed in a Facebook post that their vocalist had suffered injuries to the arm and elbow, but had been discharged from the hospital.
