I recently found a CD I’d burned a load of stuff on before leaving my job at British Gas. It included my e-mail archives. Now, I could trawl through them and find blackmail material, or I could aim a little higher.

As the most important single day so far this century, September 11th 2001 is going to be studied and analysed for years to come. Included here are the messages I sent and received on that day. It all started so well, I was in Cardiff, the sun was out. I was days away from leaving a job that had caused me far more stress than I deserved and it was just possible that things were looking up.
