If you are scared of a terrorist taking over your plane then fly Southwest. Its like Carlos Mencia says "a terrorist isnt dumb enough to highjack a Southwest plane from LA and tell a black guy and mexican that they wont be landing in Oakland." I fly Southwest just for that reason and I hope I dont have to sit in between two fatasses because there is no room at all.
The idea of being in a Sardine can whizzing above the ground at 500 MPH sitting next to the fattest, smelliest, ugliest guy on the plane doesnt SOUND that appealing but its not that bad. I get a little nervous but nothing major.
