Anybody that claims the WTC was hit by guided missiles is nuts. I saw the first plane, a Boeing 757, sticking out of the WTC building on 9/11, from a half mile away. I didn't stick around to see the second plane hit, because we didn't realize that it was deliberate - but we saw the next attack on the TV news at my job. Then we evacuated.

I still remember what the architect told me, the morning of 9/11, on the subway on the way home: the Twin Towers would collapse straight down. This is exactly what happened a short time later.
