The fog in the cabin began to appear whilst the aircraft was on the ground and remained until the plane had reached cruising altitude.

Once the plane hit rough air on an otherwise clear summers evening, the worry that some passengers felt can be seen from the picture Ficcolo snapped.

Feeling their concern, the Captain decided to offer the entire planeload of passengers free alcoholic drinks. The airline normally charges up to $7 for such luxuries.

‘I was grateful for my tiny bottles of vodka and juice. Worst turbulence ever after such a long Tarmac stay and fogging,’ Ficcolo wrote.

Smoke on a plane: The fog seemed to form on takeoff from JFK on one of the hottest days of the year

Although the fog in the cabin appeared to rise up to the chest level of many passengers, it became apparent that it was due to the hot 90 degree weather New York has been experiencing, coupled with an air conditioning system malfunction.

However, basic science is able to explain the appearance of the fog in the cabin: hot humid air outside mixing with cool conditioned air from inside the plane, and the mist begins to form.

As the plane takes off, the air pressure in the cabin decreases. The temperature of the air also decreases and if it is rapid enough the air will cool enough for the water in the air to condense instantaneously, forming the fog that the passengers witnessed.

Nothing dangerous, but still unnerving when flying at 35,000 ft.

Very cool of the pilots to offer alcohol to the passengers. I would definitely need one if I was on that flight!

If it was Ryanair you’d probably have to pay extra for the smoke.
