Funny enough I remember exactly what I was doing at the time. JFK I was building a plastic construction kit and ran out of cement.
Just after the news broadcast I went to the local convience store to get some more. As I came out of the shop the local bully and his 'gang' gave me a good beating. He was 5 years older and a lot bigger than me.
A few years later he was jailed for throwing a 5 year old girl from a play frame which left her a paraplegic.
911, I was waiting in for the Cable TV guy to replace the decoder and watched the plane strike the second tower live. I remember trying to think of a small football stadium crowd (30,000) as that was the potential death toll from the towers alone.
