I was seventeen, sitting at my parents kitchen table & listening to Radio 2, ready to go to work, it must have been about two in the afternoon or so. I remember hearing that the first tower had been hit, but I remember thinking 'oh it'll just be a light aircraft or something', you know, not really a big deal. Then the confusion and fear started to creep in to the DJ's voice as he announced that the second tower was hit and I think it was then I realised we were in the middle of something huge. I kept listening, and then he announced that the first tower had fallen.
I think I switched on the TV briefly at this point and saw the second tower fall live, and then I had to go out the door and go to work like the world was all normal. The atmosphere at work all day was weird - people were freaked out, no one really knew the scale of it or how many more planes there were and it was a bit crazy.
I don't think I'll ever, ever forget where I was during 9/11, those images are - as I'm sure is true for so many people around the world - burned on my retinas, even from 3000+ miles distance.
