Anyone with half a brain should know that in the post 9/11 world you don't joke on a commercial flight that you have a bomb in your jacket. If you do, you should expect one or all of these three things to happen. You should get beat up by the person in the seat next to you, the flight crew will call the cops, and you will be arrested.
Allegations have surfaced that a marketing employee for NVIDIA named Yushing Lui told a flight attendant on a commercial flight from San Francisco to Hong Kong that he had a bomb in his jacket. The flight was aboard a Cathay Pacific plane.
According to reports the attendant was about to hang his jacket up when he made the comment. Lui now denies that he said there was a bomb in his jacket. The man was removed from the plane and arrested and is now out on $10,000 bond and set to appear in court later.
