I was working, in splendid isolation - no radio or TV running. I was working from home, so it was only when I stopped for lunch that I found out in conversation what had happened. When I watched the news footage, it was one of those "this is big" moments. You can’t take it on in one go.

A couple of days later, I had an email from a email friend who’s brother had been in the area at the time. I got a very good first hand description of what had gone on (he had forwarded a message from his brother). That made it far more real for me than the TV could. The power of the written word should never be underestimated...

A sad day. The world changed for everyone that day.
