I watched this video the other day and found it pretty interesting. It's hard to believe it has been 20 years already?
I remember exactly where I was when this happened. I was at work and my boss' wife called to tell him to turn on the tv. We couldn't believe what we were seeing.
This article on the Daily Mail UK was also interesting.
Do you remember where you were and what you were doing when the Twin Towers were attacked on September 11th, 2001?
