In the March 12 recording, the pilot says, “F—k this place, goddamn liberal f—ks.” He then continues, making several other curse-word-laden comments before being interrupted by what seems to be an air traffic controller.

The audio is archived online at Live ATC, a website that livestreams air traffic control audio transmissions. Though the audio is fuzzy and the context of the remarks unclear, the pilot can be heard repeatedly cursing.

“F—king weirdos, probably driving around in f—king Hyundais, f—king roads and s—t that go slow as f—k,” and, “You don’t have balls unless you’re f—king rolling coal, man, goddamn it.”
