If the perpetrators of the World Trade Center plane crashes had a nuclear weapon, there's no doubt in my mind but that they would've detonated it in New York.

On 11 September, I was living in Greenwich Village, New York; my children learned to tell south from north by looking at the World Trade Center.

The plane took off at 8:10 in the morning - or that's when it was scheduled to take off. And that's when I believe it took off. I had been in my office at the Department of Justice. Someone told me that there had been the two strikes that occurred at the World Trade Center.

When I show up in New York, and I look at the skyline, it's like showing up in a mountain range. My gaze goes toward the most impressive-looking climb. It's always gone to the top of the World Trade Center.

My wife had taken off on a plane. Two airplanes had crashed into the World Trade Center. I, of course, like any other person, felt potentially devastated, panicky a little bit.

Every year, I am conscious of the anniversary of my 1974 World Trade Center walk.
