The Towers really shut down (more or less) at night? I was under the impression that they were more or less open 24/7, so there would bound to be quite a few people inside, just "burning the midnight oil". By the way, what about the Pentagon?
I was always under the impression that the Towers were essentially glorified office buildings (although there was a restaurant on the top of one of them--anybody have any ideas what its operating hours were?). Like most huge office buildings, technically they're open 24/7 (hence the need for lobby security guards to check for ID) but 99% of the workers are out the door come 5pm. I also seem to (vaguely) recall that they shut them down to tourists around this time as well. Still --20000 workers in each building and only 0.1% of them being lunatic workoholics staying late still gives you 20 people in each building, not counting the ubiquitous cleaning crews, security guards, maintainence people, etc wandering around. Many of the offices were law firms and advertising companies, so I can see that percentage being a bit higher than 0.1%
But--as been pointed out by DuQuense--it's symbolic. Remember the truck bomb in the WTC parking garage that killed a 'whopping' 7 people? Remember how nuts people went then? How chaotic the city got? How much press and media attention it got? All the dark mutterings about 'bombing some arabs' for revenge? Now you've got TWO hijacked planes AND completely destroyed towers. Even if it was a ridiculously low casualty figure of, say, 5 people or so, people will still be screaming for blood. Hell--they'll be saying stuff like 'What if these idiots had attacked at 9 am instead of 9pm? Why, there would have been
thousands dead! Let's make sure they don't do a repeat performance..."
As for the pentagon--aren't military buildings 24/7?
