We'd been for a highly unusual team-building lunch in Charlotte Street, and I had a meeting to get back to so I left everyone else in the restaurant and walked back to the office. On the way, I saw, on TV screens inside a film company's display windows, the image of the first tower burning and "BREAKING NEWS" scrolling across the screen. I got back to work and immediately checked the web, despite most of my colleagues being clustered round the TV in reception.

No-one did any work that day, and I think the events in NY brought the team together more than any lunch could. I've never had such a hollow, sad, scared feeling, not even during the 7/7 bombings in London in which a close friend of mine was killed.
