Rough air left 43 passengers and crew members injured, one seriously, aboard a Northwest Airlines jumbo jet Friday as the flight from Manila was in a holding pattern off Chiba Prefecture awaiting clearance to land at Narita airport, officials said.

The injured, who apparently were not strapped in although the seat belt sign had been turned on, were taken to hospitals near the airport. It was reported that one casualty suffered a broken neck.

The Boeing 747-400 with 408 passengers and 14 crew members aboard landed at Narita International Airport at around 12:20 p.m. Friday, the Land, Infrastructure, Transport and Tourism Ministry said.
