This topic is a nice idea, grip. Thanks for starting it.
Unfortunately, I don't have much of a story to tell. I was watching CNN at the time, drinking a cup of tea and trying to wake up.
For some reason I don't remember now, CNN was showing a live shot of the towers and the world got to watch the attack in real time.
At first it just looked like a plane was flying too low. But then when the plane went into the tower and never came out the other side I thought it was a terrible crash. When the second plane hit, there was no longer any question that it was not an accident but a terrorist attack.
It was a terrible memory that I am sure I will never forget.
