I understand why we have the screening, but it is fighting the war of the past. I would rather they give every able bodied passenger a knife to defend the cabin if necessary, keep the cockpit door locked, and disperse the TSA employees around the airport perimeter to make sure there is no one ready to take down an airliner with a shoulder-fired Stinger.

What I fear is a random attack on an airliner, or worse yet, a coordinated attack where Stingers are fired at 10-15 airliners at different locations simultaneously. But at least all the pax on those planes will not have any nail files, screwdrivers or corkscrews!
