Oh I see, the terrorist would fly up to the restricted area and turn
around
because the sectional says you can't go there. Those are some darn
well
behaved terrorist in my book.

Let's assume the prohibited zone was the old 3-mile ring. Now, a plane
has just breached the outside edge of the ring. In 2 minutes it will be
on top of the Capitol building. No time to send F-16s up to put on a
fireworks show; all you can do now is fire a missile. And if it's a
Learjet, you have more like 30 seconds.

So, instead of having a line in the sky 30 miles out that you *might*
get shot for crossing, you have a line 3 miles out that you
*definitely* get shot for crossing. How does this improve the
situation?

3. Light aircraft are a possible means of delivering a weapon of
some
kind.

A baby buggy is just as good a tool.

And if you took your baby buggy and ran at full speed towards the gates
of the White House, you would be dealt with equally roughly.
