Apparently multiple airline flights have experienced a moaning sound over the intercom. Here is video of the very weird experience.
The weirdest flight ever. These sounds started over the intercom before takeoff and continued throughout the flight. They couldn’t stop it, and after landing still had no idea what it was. pic.twitter.com/F8lJlZHJ63
AA was hacked, possibly by an angry or prankster employee.
Someone at a semi-automated radio station I once worked at slipped a taped “cart” into the machine which held dozens of similar carts with music, ads and announcements which were programmed to play at various times. The “ringer” cart (this was holiday season) played a short selection of Xmas music with Santa in the background going ho-ho-ho, until Santa developed a horrible cough, started gagging and (presumably) expired.
