That is the last thing I am thinking about. I have no personal
desire to carry a weapon, its not a glamour thing. It is the last chance to stop terrorists before one of two things happens, they turn it into a cruise missle, or we get shot down. Cabin training is a great idea, as are LEO's. They add a layered defence against hijackers. You hope that they will never make it through the door, but you plan for the worst, and that they will. Sept11 was exceedingly effective, who is to say it won't be tried again.
Some here have said that they will be pulverized by the pax, look at the UA flight where they fought back against the bad guys, they crashed. While better to put it into an open field than a building, its not the desired outcome. Imagine being on a plane with a number of hijackers taking it over, bent on destruction. Sitting, watching as they break into the cockpit. You know your best chance is a flight deck that can fight back rather than giving up the plane once the door is breeched. As the hijackers go through the door, you now know your fate rests with the hijackers and/or some politician who is about to order the trailing fighter to shoot. That scenario may still come true with an armed pilot, but at least one more link in the chain to possibly stop it.
Every time you get on an air carrier aircraft, you are putting your life in our hands. You trust in our abilities to get you from A to B. Arming pilots is just an extends our ability to do so. As hazards to aviation are recognized, pilots adapt to new procedures, and welcome new equipment to overcome them. Be it CFIT, runway incursions or hijackings, give us the training and equipment to try to overcome.
