Flight from Seoul to Dallas-Fort Worth lands at Tokyo after flight turbulence hurts 5

An American Airlines jet encountered severe air turbulence shortly after takeoff from Seoul, South Korea, injuring four passengers and a crew member.

A statement issued by the Fort Worth, Texas-based carrier says American Flight 280 was headed for Dallas-Fort Worth when the Boeing 777-200 met with air turbulence.

On-board injuries prompted the crew to make an unscheduled landing at Narita International Airport in Tokyo, where passengers and crew members seeking medical attention were evaluated and treated. The American statement says four of the 240 passengers on board and one of the crew of 15 needed hospital treatment, but none of those injuries are life-threatening.

Officials say the remaining passengers won't continue their travel to DFW until Wednesday and have been taken to hotels to spend the night.
