Here in Oz
I was sitting at my desk reading emails on my TAM at about 7am Darwin time (5:30pm New York time, Sept 11) when my fiancee called out to me from downstairs. She said there was something really wrong with the tv, and that something bad had happened.
She "couldn't" change the channel... because every (free to air) channel here in Oz was showing the exact same thing... as in, EXACTLY the same newsfeed, coming from one of the major US news sources.
There was not alot of voice-over to explain what had happened... I remember thinking... Someone has bombed the USA... Nothing else made sense, looking at the footage of ash covered New York streets...
Eventually my fiancee and I went to our respective jobs... I worked in a 6 storey office building... and yes, even at that level that day we talked about evacuations and likelihood (ie minimal, but still) of an attempted attack... We had the radio on all day, and I had left a VHS tape in the VCR just taping the whole day's news... not that I've ever watched it...
My fiancee had a much harder time. She worked in childcare, and had a bunch of kids to look after, who were too young to comprehend... but old enough to know something was wrong by the faces of their parents and other adults. I know in her centre, they did a lot of hopping in and out of the staffroom to get any new information, and to have some time out...
For what it's worth (not much, now), I just would like to say I think it's sad that the towers have not been rebuilt "as was"... (that is to say, at least outwardly, with better structural designs inside). Yes, I know I'm not from New York, nor even American, but if the Sydney Opera House had been destroyed by terrorism, I know I'd have wanted it rebuilt...
