American Airlines flight video of bad turbulence. "An American Airlines jet encountered severe air turbulence shortly after taking off from Seoul, South Korea, prompting an unscheduled landing at Narita International Airport in Tokyo after 14 people asked for medical attention. The airline says four passengers and a crew member needed hospital treatment, but none of those injuries are life-threatening." Was on a flight in a rickety ass plane in Russia one time. It was pretty damn close to this. It gets scary.
