Where were you when you first heard about 9/11? I know exactly where I was!
I was working for a computer company called Logica at the time. I worked in their mobile networks section on the billing and switching for their pay as you go systems. I was what they called a technical lead. I was a database administrator and more importantly at this time I wrote the software that upgraded the billing software to the next version.
So, they sent me out to Athens for 5 days to help out with an upgrade for Panafon which later became Vodafone Greece. I was really looking forward to this as I had never been to Athens and always wanted to go.
