I heard the plane that crashed in PA was deliberately crashed by one of the pilots. If that's true, and the plane was hijacked and en route to another target, I applaud the pilot.
Frankly, I'm still in shock with the whole incident. No matter how much I pinch myself, I still can't wake up. I do agree that this is unlikely to lead to WW3, as in most of the civilized world is on our side.
