A Japanese domestic flight was forced to make an emergency landing on the island of Okinawa today after white haze was seen in the Boeing's cockpit, carrier All Nippon Airways said.

The pilot on flight ANA 90, travelling from southern island of Ishigaki to Haneda airport in Tokyo, noticed the "haze-like thing" around 12:50 pm local time as the plane flew near Okinawa, less than an hour after departure, according to an ANA spokeswoman.

"The pilot decided to divert to Naha airport" on Okinawa, she said.

The haze disappeared quickly in the Boeing 767, but the pilot reported a burning smell, she said.

None of the plane's 101 passengers and eight crew members was hurt, and passengers were switched to another flight to Tokyo.

ANA stressed that the case was not regarded as a serious incident, but added that they are investigating the cause.
