This tragedy of course is first about the people who have been killed. I cannot wipe the image of an airliner slamming into the Twin Towers from my mind. Any one of us could have been on that plane, or heading to a meeting downtown. My own father walks to work by those buildings, and only by a fluke did he end up elsewhere at the time of the attack. Like all of our readers, I know people who work in the World Trade Center and Arlington, Virginia, and I am still trying to find out if they are alive. My heart and sorrow goes out to the victims, their friends and their family.
