The measures you propose could by no means produce an impenetrable blanket of security.
Nor did I
ever remotely suggest such a thing, in any way, shape, or form. I stated exactly the contrary; anything is a step in the right direction, and there are literally thousands of ways that security can be improved...presently there is none.
(By the way, I think it's quite remarkable that you even predicted the aircraft TYPE for 9/11.)
I didn't "predict" jack. It was inevitable. If I were a terrorist, I would have used an aircraft such as a 757 or 767 to strike one of the most obvious and distinctive targets I could. The WTC was it. Then again, so was the Pentagon. That's not a prediction; it was an obvious choice, and it was all but inevitable.
I'll go you one further. Frequently when flying, or jumpseating, I carried five blades or more with me, all legal to pass through security. A small folder, a leatherman, a swiss army knife, and the ever present spyderco cricket. (which TSA ironically confiscated, last year). I frequently questioned the efficacy of allowing blades through security.
I was always told that nobody could do damage with a short blade. What a silly notion, I was told. I noted that a pencil will do the same damage as a handgun if you know how to use it. My assertion was then, and was borne true, that short blades make ideal weapons in a rapid tactical takedown...and they do.
I've said it since. You're probably one of the brightsparks that feels a takedown can't happen today, because the passengers will heroically rise up and defend, that doors are inpenetrable. What a stupid, naive notion, but a commonly held one all the same. A ribbon charge stored in a shoe will surgically remove the door, neater than cheese. One or two others using the fatal funnel concept can hold the aircraft while the door is being blown...the design of the interior of all airplanes makes this possible. And blades still work wonders...cut the first few wide, and the others slip in the blood, recoil at the sight, and the bodies pile in the funnel to form a defensive barrier.
I said that blades were a threat before, and they are now. Metal doesn't pass security well, but carbon fiber does. A credit card will work, too. The threat is still there. That's no prediction. That's stating the obvious. I didn't predict 09/11. It was **CENSORED****CENSORED****CENSORED****CENSORED**ed obvious. If it wasn't obvious to you, it's not lack of predictability; it's naivete and blindness.
Then again, six months before we ever thought of 09/11 and Afghanistan, I could clearly see that we were preparing for war there. And I said as much. When we began to villify the Taliban and begin to work the public up against the Afghanis in the media in the months preceeding 09/11, it was obvious. Only because we set it up...but it was obvious that the public was being primed for it. A blind man could see that.
OH, and after we ground the GA fleet, we should go after the REAL threat - - Experimentals ! !
Probably goes without saying, but experiemental aircraft are part of general avaition.
The terrorists have already beaten some of us.
Speak for yourself.
