At least 37 people were injured aboard an Air Canada flight that was severely turbulenced and had to land urgently.
The plane – carrying 284 passengers and crew members – was traveling from Vancouver to Sydney but was diverted to Hawaii.
Thirty people were taken to Honolulu Hospital on Thursday. Nine had serious injuries, say officials.
Air Canada said the Boeing 777-200 "had a sudden turbulence of clear air … two hours after Hawaii".
He added that he was organizing hotels in Honolulu until a new flight to Australia could be organized.
The plane landed in Hawaii at 6:46 am local time (16:46 GMT) on Thursday.
"We faced turbulence and we all found ourselves on the roof, and everything fell to the ground … people flew," said Jess Smith, a passenger on board the plane, to the local television channel KHON.

"Some people who were not attached to the inside, you saw them go up in the air and bang your head against the roof and all, so it was quite intense," said one other passenger at the station.
Alex Macdonald of Brisbane told Canadian television channel CBC News that the passengers on board were "extremely shocked".
"I saw the people in front of me hit the upper luggage compartments and then put themselves in their place," she added.
The photographs taken inside the aircraft show that oxygen masks were released and service carts reversed during the incident.
What is the turbulence of the air?
CAT – the turbulence of clear air – occurs in blue skies, otherwise calm and clear, without any visual indication, such as clouds.
This occurs when air masses moving at different speeds meet and can not be identified with the naked eye or conventional radar.
Pilots use reports from other aircraft, transmitted through air traffic control, to follow in CAT's footsteps.
Passengers reported that the cabin was bleeding and damaged by passengers hitting the ceiling of the aircraft.
A social media post from a passenger showed him wearing a neck brace at the airport, accompanied by the caption: "Unexpected Vacation in Hawaii".
An Australian group of countries, Hurricane Fall, was also in flight at that time.
They confirmed in a message on Facebook that their singer had been injured on the arm and elbow but had been released from the hospital.
