‘An ANA All Nippon Airways Boeing 767-300 from Guangzhou (China) to Tokyo (Japan) with 163 passengers and 10 crew, was in the initial climb out of Guangzhou when mist appeared in the cabin and cockpit causing low visibility. The crew levelled off a low altitude and returned to Guangzhou for a safe landing’. ‘Passenger Craig Campbell reported he was seated in the aft cabin. They did not observe any haze or mist, however noticed a “strong smell of phosphorous/flint/burning”. He and other passengers coffered their noses. The engines and climb slowed shortly afterwards. The crew announced there was no problem, just some smell, then the crew told the passengers they were checking some smell and issues subsequently concluding there was nothing wrong, correcting themselves now stating there were some issues but all was okay and finally the crew announced they were returning to the airport due to some problems’. After Landing - ‘ A number of passengers seated in the front of the cabin, who had reported seeing smoke, were quickly taken away and were not seen again. The crew also disappeared.’
