Lox: I'm surprised that no-one mentioned that Towering Inferno was, in fact, a movie, and that, even in the movie, the method used failed to rescue all of theose trapped even when there were (if I remember correctly) only 100 or so fictional people trapped.

There are skyscrapers across all of the developed world. They arose out of a desire to show off technological prowess - to say : look what we can do..
now - we should be saying - look what we did.

We built buildings that can trap the occupants. I know that the circumstances surrounding this were exceptional - at one time we could have said *unthinkable* - but now we have to think in those terms always.

We can ignore something that might never happen, but not something that has happened, with drastic terrifying consequences. We may eliminate these terrorists, but I believe that what happened last week just "upped the ante" for events of this type. Hijacking for hostages was one thing. It's been around for over 30 years. We lived with that. Hijacking for usage as missiles has only just begun.

Other comentators have pointed out that it needn't be a plane, or a bomb.
These buildings and many others are now targets.
