More than 20 people have been hurt by turbulence on a flight from Washington DC to Tokyo.
Although there were no serious injuries, at least one passenger may have fractured a leg, and others have complained of pain and bruising.
Police at Tokyo's Narita International airport said the United Airlines flight hit turbulence over Alaska but the Boeing 747 eventually managed to land on schedule.
United Airlines spokesman Mike Trevino said that about halfway into the 13-hour flight, the pilot advised passengers to put on their seat belts.
A short time later, the plane "experienced moderate turbulence."
