How do you justify that leap? Perhaps, you aren't aware that it is going to cost $900 million to allow pilots to carry?
So? 9-11 cost New York City ALONE up to 95 BILLION dollars, and that doesn't count what it is costing America as a whole.
Perhaps you haven't read that al-Qaeda was planning a SECOND wave of terrorist hijacked planes for early 2002.
I don't know where you're from, but it ain't over yet, and some pilots definitely want to have a last resort to defend themselves and their plane and passengers the next time someone blows up the door to the flight deck and comes in to cut their throats.
