Poltergeist. United States

An extremely strange phenomenon went viral on social networks after the publication of the film's producer Emerson Collins of a recording he made during a flight from Los Angeles to Dallas on September 6.

"The strangest flight ever," Collins tweeted. "These sounds started on the intercom before takeoff and continued throughout the flight. They couldn't stop it, and after landing they didn't understand what it was."

Described as a cross between orgasm and vomiting, the sounds were like a kind of moan, as if someone was in pain. At different times of the flight, you could hear these strange sounds broadcast to everyone on the plane through the intercom. Even the crew had to inform the passengers about it.

"Ladies and gentlemen, we understand that there is a very annoying sound in public intercoms," said one of the flight attendants. "The flight deck is trying to troubleshoot, trying to shut it down, so bear with us. We know that this is a very strange anomaly, and none of us likes it."

For her part, Sarah Janz, a spokeswoman for American, later issued an official statement. Los Angeles Times.

"Our maintenance team thoroughly inspected the aircraft and the speakerphone system and determined that the sounds were caused by a mechanical malfunction of the speakerphone amplifier, which increases the volume of the speakerphone system when the engines are running." Jantz said.

This could be a logical and rational explanation, but the mystery does not end there, as the head of the technology department, Bradley P. Allen, testified that he also heard the same strange sounds during an American Airlines flight in July, which apparently indicates that this is not an isolated case. Moreover, he recalled that this had happened several times, and that some passengers were scared.

"My wife and I ran into this on flight AA in July"— one of the passengers explained. "To be clear, it sounded like the moans of a person in severe pain. The crew said it had happened before and had no explanation. It was briefly 3 or 4 times at the beginning of the flight, then stopped. These sounds started on the intercom before takeoff and continued throughout the flight. They couldn't stop it, and after landing they didn't understand what it was. I wrote it down for about fifteen minutes, then again during the service. It was quieter during the flight for a while. The captain just came up and told us that they don't think anyone is hacking the intercom."

This is just one of many strange stories about mysterious sounds on American Airlines flights. It should also be added that the flights were carried out on Boeing and Airbus aircraft using different airports and with different destinations and crews. The only common element was that they were all American Airlines flights with some kind of connection to one of the Los Angeles airports.
