Twenty-two years ago I'd been at work for less than an hour when I checked the news on my browser and saw the first few minutes of coverage about a plane hitting the north tower. Like so many, I assumed that some small plane had somehow blown it. Then the websites started freezing up from so many people logging on. We had no TV in our office, but I knew where there was one. Housemate Kristi worked in the same building and I walked down to her floor to see what they knew. We went into her boss's office where the TV was, just in time to see the second plane hit. My memory tells me we watched that one live, but I think I have a way to confirm or disprove that. I went back upstairs and told the people in our office what we knew so far, and by then we'd heard that the Pentagon had been hit as well. I think within that next hour the office building management called the employees from all the companies outside, fire-drill style, and it was decided that the building would close for the rest of the day. One reason for that was that the building is on a hill across the highway from the local airport, and at that point no one knew anything but that proximity to any airport or airplane could be a risk. We all went home, and at my house we settled in to watch the developing news for literally the rest of the day. I surfed channels, but my main choice was Peter Jennings and I didn't call it quits till midnight.
A side story is Kristi's brother who was working in one of the buildings across the West Side Highway from the towers, and how he had gotten away from there just in time and walked 40 or 50 blocks north to stay clear of it.
DR singdaw, where in Danbury was your office? Our building was Lee Farm Corporate Park across Route 7 from the Danbury Airport.
