The Japan Transport Safety Board is looking into why passengers seated at the back of a Northwest Airlines 747 were the most severely injured when it hit clear air turbulence over Tokyo’s Narita Airport on Friday, according to Japan’s Daily Yomiuri.
The safety board will question crew members to find out whether they had checked that passengers at the back of the aircraft were seated and had their seat belts on, the paper reported. Witnesses said that some passengers hit the ceiling so hard that the interior of the jet was damaged.
The story also said that when the captain first notified the airline of injuries, he believed that only a couple of passengers were hurt. After the jet landed, dozens of people were found to have injuries, a few of them serious.
