I was working in Amsterdam. At the start of the day (which was beautifully sunny, like in New York) I'd been watching the Beeb news talking about Tony Blair going to the TUC conference to have a row with them about Clause 4 (at least I think that's what it was, although looking on Wiki it seems Clause 4 had been done for some years earlier). I was thinking he was really in trouble, though.
I heard about it when someone in my team came over to say 'a plane has crashed into one of the World Trade Centre towers' and I thought 'oh no what a terrible accident' and then he said '.. and another one has crashed into the other one'. I remember thinking 'my god has someone interfered with air traffic control or something?' (causing the planes to veer into the towers somehow).
Completely unable to access any news website, a lot of what I heard next came from Yahoo Messenger from a friend in Malaysia. I remember hearing about the plane at the Pentagon and that was much more frightening in some way, you don't imagine the Pentagon as being vulnerable to attack (and by this point it felt like an attack). And also that the towers had fallen, I couldn't imagine how that had happened and imagined them having collapsed sideways like a tree being felled.
I also remember hearing about the plane in Pennsylvania although reports were very confused and sketchy, I think at first there were reports it had come down on a school? I was certainly concerned that other cities were going to be attacked next.
We went home by train and everyone was trying to get info via text message, I remember one guy on the train saying to us "Bush is finished". We turned on the TV at home and that was the first time we'd really seen anything. It was staggering. Manhattan completely hidden by smoke.
It seemed so utterly surreal - up until that moment, plane hijackings had been something largely survivable - as a passenger you knew to keep quiet and comply with their demands and then they would land the plane somewhere random and probably someone would have to pay a load of cash but likely you would get away. We know now that the people in the later planes knew that wasn't going to be what happened to them.
I had to fly back from Schiphol a few days later, the first day flights were going back to the US. The queues stretched the entire length of the airport and you were allowed to take almost nothing on board, just your laptop in a clear plastic bag (I might say this made for very quick boarding of flights for once). Everything was very subdued and I was very nervous whenever anyone stood up on the flight (which was only going back to the UK so not a long one) wondering if this was it.
We got word the following morning that the people in our New York office were safe.
Thoughts to all who lost loved ones that day and as a result of that day.
