NEWS Twitter-joking security expert barred from another United flight, lawyer says

It seems that joking about messing with the security systems on a United Airlines flight might be asking for more trouble than you imagine. Earlier this week, computer security researcher Chris Roberts was removed from a United flight by the FBI. His transgression was to have tweeted: “Find myself on a 737/800, lets see Box-IFE-ICE-SATCOM, ? Shall we start playing with EICAS messages? “PASS OXYGEN ON” Anyone ? :)” For those who don’t speak this peculiar strain of English, he was jesting that he could hack into the communication systems of the plane and even make the oxygen masks appear.
