I was in New York several years ago, did the whole tourist thing - I remember distinctly being in the WTC, amazing height - the buildings would sway in the breeze up to 3 feet (because of the height)...
watching TV was so surreal, like watching a different version of Independence Day

kids will watch King Kong ('80s version) and think the whole movie is fake now

I can't imagine what was in the peoples minds jumping off that building! Cars are smaller than ants from that height!
My prayers out to all the families and friends of the thousands who have died!
