Andy,
We are all more aware of the scale of this than you might think. Certainly in the UK the television coverage has been enormous - as it was right to be.
It has been brought home to us with the knowledge that this is the worse case of terrorism for Britain with the numbers of Britons who were in the World Trade Center. We know that the effect on the US is very much greater.
When I saw the second aircraft to hit the south tower (the first shown on TV) I thought that it was a 737 - and I fly them! The fact that it was a 767 brought home to me the enormous scale of the tragedy.
