I was 26, working in an Outpatients department. It was a quiet afternoon, and I remember seeing the Outpatients Sister coming by with an odd expression on her face, and she said, "New York's in flames, planes have crashed into the World Trade Centre". My colleagues and I went straight onto our computers to find out what had happened, then we went to the Children's Outpatients, which was empty that afternoon, as it was the only part of the department that had a screen, usually for showing cartoons. We watched the news for a long time, and I remember seeing the footage of the second tower falling over and over - I actually have no idea if I saw this happen live or if I just saw a repeat of the footage. Then I went home and watched the news for hours. I found the lack of places in the sky for the next day or two really eerie - where I lived and worked was right on the flight path to Heathrow so there would usually be a plane every minute or so, and a sky without planes felt so odd.
