This may look like a scene from a horror movie but it was a reality for passengers on board an Air China flight on Saturday (May 23).
According to netizen ‘long-limbed uncle’, fog filled the cabin before the plane took off from Shenzhen’s Bao'an Airport.
He added that the fog was probably caused by the high humidity level outside mixing with the air conditioning inside the plane, turning it into a “sauna”.
While the fog was supposed to clear up once the plane reaches cruising altitude, it was still very much present in photos taken when flight attendants were serving meals.
Thankfully, no one opened the emergency exit to get some fresh air.
