PHOTO: Aircraft fills with fog during Delta Airlines flight in the United States

Smoke fills a Delta Airlines flight from New York [Photo: Reddit]
Here’s an interesting photo from a recent Delta Airlines flight in the United States… imagine boarding an aircraft and seeing this in the cabin!

Posted earlier this week on the popular website Reddit, the photo was taken by user ‘Ficcolo’ during his flight out of JFK International Airport in New York.

“Last night flying out of JFK....this happened and freaked us out. Disco rave flight!” he commented.

Apparently, the fog could be seen while the aircraft was still grounded, and remained visible until the plane had reached cruising altitude. It reached up to the chest level of passengers.

Comments suggest this was due to the hot 90 degree weather New York has been experiencing, coupled with an air conditioning system malfunction.

“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,” reported The Daily Mail.

“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.”

Although the fog was not considered a safety concern, some passengers were naturally a little concerned. As a result, the captain waived a $7 charge for alcoholic drinks – helping to calm some nerves along the way!

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

  1. When air cycle units blow hot/cold you see this. It's just condensation and not harmful. Though of course the self loading cargo don't like it ;)

  3. It's a Pan Am curse! A subtle message to Delta. LOL!

  6. That's no smoke. Only condensed air.

  7. Looks a bit like view of the Golden Gate from the Marin headlands. Same physics.

    The heat had nothing to do with it, otherwise we would see this throughout the world on a daily occurrence. Also why only on this flight out of NY and not all flights?

    Personally, my guess is a seal.in the ACM is on its way out. They did report a faulty aircon sys. However as I am not there to smell, see and even taste the "fog", it is difficult to even begin thinking what the cause is.

    During ground pressure checks some guys have a nasty habit of opening the outflow valve quickly when at high cabin pressure which causes the water vapour to separate and make a dense fog in the cabin, but it tends to be all over and not just at floor level.

    Would be interesting to actually have seen this so as to be able to diagnose correctly.

    Air conditioner, hot and humid weather on ground. This is the result. Absolutely normal in some places. You can expect things like this in most Caribbean destinations... :P

      I am inclined to agree, which then tells me this airline takes shortcuts when it comes to replacing coalester bags. The water separators are not doing their jobs.

    2. You are absolutely right Sir, maintenance is the culprit.

  12. Dan Air's BA146 used to do that all the time. Came out the vents.

  13. It's a FUNNY Looking Sight to see in the Cabin!!!

  14. This is common onboard aircraft due to humidity. I know it would've frighten a few passengers though.

  15. It is not uncommon to get a fog when trying to do a leak check on the aircraft pressurization system with the air conditioning cranked to full cold. In fact when I was a newbee, two old timers tried to scare me by creating a fog in the back of a F27. Didn't scare me, I could tell the difference between smoke and fog.

  17. Looks like high OAT combined with a not so efficient pack with moisture in the air. BTW what type Aircraft was this?

    ReplyDelete
  18. Geez, this happens all the time in any high humidity climate...and of course Transylvania! ;)

  19. At first I thought it was a pressurization problem, but then I read the rest of the article. Cool!
