TOKYO (AP) - Cabin pressure suddenly rose in an All Nippon Airways Boeing 737-500 jet, forcing the domestic flight in south-western Japan to fly at a lower altitude until it landed safely at its destination. None of the 108 people aboard were injured.
ANA spokesman Yoichi Uchida said the flight on Wednesday from Fukuoka to Okinawa was at 11,000m when cabin-pressure controls failed. It dropped to 3,000m, where natural pressures are more endurable for passengers, to complete the flight.
Passengers did not need oxygen masks, although some may have felt ear pain, he said. Cabin pressure returned to normal during the flight. The cause of the problem is under investigation.
ANA says two flights scheduled later in the day for the same jet were cancelled.
