It's interesting how so much is focused on airport security. Let's assume that we figured out how to make airline terminals 100% terrorist-safe and completely secure, no exceptions. (Yeah, it's a fantasy, but stay with me...) At that point the terrorists will give up on the airports and pick something different. Remember that the first attack on the WTC, and the (domestic!) attack on OK City were TRUCK bombs. What's to stop someone from hijacking a tanker truck and detonating it? Trucker school must be easier than pilot school, right? And if the terrorists are still hot and heavy for airplanes, they could bring down an airplane without actually going through airport security. At most airports I know of, the planes are vulnerable to ground-based attack on takeoff and landing. Not the same as crashing one into a building, but it seems unlikely that that attack is repeatable.
