Passengers on at least three American Airlines flights reported bizarre moaning and groaning noises from in-flight intercom systems.
In a viral video, one passenger described the sound as "somewhere between an orgasm and vomiting."
According to an American Airlines spokesperson, the PA systems "are hardwired and there is no external access."
However, it appears this wasn't the only American Airlines flight that has been subject to strange noises.
The American Airlines spokesperson told Insider the company is reviewing the additional claims, and also noted that there is no WiFi component to the PA systems, which would make an external hack difficult.
