They would probably notice that but it does seem like some former passenger most likely installed something that's patched into the system. It may just be a recording from a flash drive. Or it could also be more sophisticated and patch into the wifi as well. You could also imagine it having a microphone for added hijinx but none of the interactions seem to suggest that.

I've flown American six times in the last ten days, and four of the flights had chaos with the entertainment system. No groans or heavy breathing on the PA, but flight attendants had to "reboot the system" once or twice every flight.

I once captured the Linux boot screen of a United Boeing 737 infotainment system. Apparently I still got that photo. OCRed text for lols:

This is on multiple social media sites - did you read the article?

A new social media marketing strategy?

Marketing? "Come fly our planes and experience the PA ghost?"

I feel like that would only target a very small percentage of potential customers.

Had the same thought. This is like “DOOM running on …” but for fart jokes, and I can’t imagine that there’s a whole gang of pranksters doing this.

The skies are full of "owo" https://twitter.com/Lekonish/status/1455696144571326466

Well, that's not a surprise, at least. I think I've known more A&P mechanics who were furries than weren't.

This could be an internal thing done as to arouse curiosity and attract passengers over the Halloween and the following holiday season.

Far too early for Halloween, and I can't imagine such a company doing this as a marketing stunt.

It doesn’t sound particularly human and it seems like it would be a weird hobby to go on a bunch of flights and cause these strange sounds. Surely a prankster would get bored and move on to something like music or silly messages. (And if the airline believed passengers were doing it they might correlate flight records or something?) I think I’d probably believe that it’s just some elctromechanical issue. I doubt fixi…

We must be listening to different tapes. Sounds very much human, very much male, very much young

The first burst sounds like a grazing animal. Then definitely becomes very human sounding.

> for safety reasons all the entertainment is paused when they use the public address system. It's more common for the entertainment to be muted without being paused. I assume that's as a convenience to the passengers.

Yeah great convenience to miss part of the movie because they want to sell inflight shopping :P I had totally forgotten about this because I haven't flown long-haul in decades. I suppose these days I would just watch video on my tablet anyway.

> Yeah great convenience to miss part of the movie

Nobody said a feature implemented as a convenience to the user had to make things more convenient for the user. They're barely even related concepts.

For those interested in the various aircraft systems for PA (public address) and aircraft status system for aircrew, I found this interesting training doc PDF online [1] for the A320/321. I have been looking at section "03-010 CABIN INTERCOMMUNICATION DATA SYSTEM" It does not mention the "medical intercom jacks" in overhead bins that are mentioned at the end of the article [1]: https://caisatech.net/uploads/XXI_3_AIR…

A bit of searching for airplane medical communications jacks turned up this picture: https://aviation.stackexchange.com/questions/12776/how-are-t... Jacking into that would not be inconspicuous.

Could that pick up a transmission from a device designed to emit RF stored in the overhead above?

I could definitely be wrong but my go-to assumption when the source originates from Tiktok is to assume it's fake or staged.

In this article the author claims to have talked to American Airlines about it:

>American Airlines inspected the Boeing 737-800 as well as the P.A. system itself after these reports. They tell me that maintenance “determined the sounds were caused by an issue with the PA amplifier. There was no external access to the system.”
