It's about what the people INSIDE went through.
While we sat there and watched on TV, they had no clue what was going on, to the point that the people in the North Tower didn't even know the South Tower had fallen.
I had just gotten home from a doctor's appointment where I heard about the first plane. I called a friend and turned on the tv right away. It was only a couple minutes and we saw the second plane go into the south tower.
It still infuriates me to no end...the bastards!
