Passengers got scared and confused when they found themselves surrounded by a strange mist blowing into the cabin on a Cebu Pacific Airlines flight from China to the Philippines on May 5, 2023.

The footage shows the steamy air moving inside the aircraft as passengers watch the hostess performing a safety demonstration.

Luckily, there was nothing to worry about. The vapor was simply caused by the hot outside air condensing with the plane's onboard air conditioning.

The footage was filmed by social media user @LeiShao on May 5.
