OK … we know what happened … NOW I wanna know what ways there are to hack into that system. It’s not a WiFi or bluetooth type system so … what ways are there to hack into it. Is that system digital or is it analog? Someone didn’t hold a cell phone close to a wire and breathe heavy. And airliners are full enough that if someone were somehow transmitting aboard the aircraft, there’d likely be a witness. This is an ‘inside’ job by someone who knows how that system works and wanted to play a prank. Once they know how they got in, they know how to secure it.
And who is this guy in the video … HE doesn’t seem very surprised and – in fact – seems pleasantly amused. Did they determine HE isn’t somehow involved.
Meanwhile, all the kinky people will be flying American now … 
AND … the bad boys have a new idea to spoil our flying days. I’ve heard it all, now.
