I was on my way into work now, driving to Jersey City and the (last) PATH train to the World Trade Center. #911

I stood on the last PATH train. Crowded, as usual. #911

I didn't want to go to New York that day. My 10 am meeting was to plan layoffs at CondéNet. #911

Wow RT @currycolleen: @jeffjarvis My dad was a conductor on that train.

I didn't notice what a beautiful morning it was until I looked up at the North Tower and the sky. #911

Indeed. RT @currycolleen: @jeffjarvis He got home and picked me up from high school. Thank God.

At this moment at Journal Square, I got on that last PATH train to the WTC. #911

It was just another commute to New York. Not sure why I took the World Trade Center PATH instead of the train to midtown. #911

My PATH train was probably going under the river about now. #911

At this moment, my PATH train entered the World Trade Center. #911

The first jet hit the first tower now. #911

I got off my PATH train, noticing nothing different at first. #911

I came up the long, broad escalator to the Trade Center's concourse. Something was different, quite odd: Silence. It was never quiet. #911

At the top of the escalator, I saw virtually no one. It was never not crowded. #911

I wondered what had happened. Behind me, I saw a small bit of smoke. I thought it was a minor track fire. I didn't rush. #911

I saw the concourse of the World Trade Center dotted everywhere with empty women's shoes. I could not imagine why. #911

I turned to a stranger; said, "What's up with the shoes." He gave me a dirty look for talking to him. That was the last old-NY moment. #911

I just walked through the concourse, seeing no cause for concern yet. #911

I came up under WTC 5 and the bookstore there. Still quiet. Still not concerned, just puzzled at what was happening. #911

I wanted to buy a newspaper but was peeved that the newsstand was in the process of closing. #911

I came out of the Trade Center and a woman cop there screamed at us: "RUN! RUN!" I will always remember her face, with gratitude. #911

I ran across the street amid debris. I did not keep running. I stopped between the hotel and Century 21 and turned around. #911

Now I saw black smoke and orange flames from the top of the North Tower with debris still raining. #911

No one knew what had happened. The news was speculation,. Some thought a plane had hit. It sounded impossibly absurd. #911

We hardly spoke, the strangers there. We just stared up. #911
