That day was a sad, strange day.
I began the day by making my weekly trip from Long Island (western Nassau County) to Jersey City, New Jersey, where my (former) company had relocated to 4 months earlier from Tower #7, WTC, our location for the previous 10 years. I had just started my mostly telecommuting deal the month before but hadn't been to the office in 2 weeks because I was away on vacation the previous (Labor Day) weekend.
I boarded the 8:54 AM LIRR train to Penn Station where I would walk one crosstown block from 7th Avenue to 6th Avenue on 33rd Street to board a PATH train (a small subway-like system connecting NJ to Manhattan) to Jersey City. Only a few minutes into the trip, another passenger yelled out, "a plane hit the World Trade Center," after hearing it through his Walkman radio. He was listening to Howard Stern, so we wondered how truthful it was.
I was sitting on the left side of the train, window seat, so from the elevated tracks I could see way in the distance (about 20 miles away) smoke coming from one of the two towers. Other passengers were quickly learning something bad had happened, either through their radios, cell phone calls, or by looking out the window like I did.
A few minutes later, the train pulled into Jamaica Station, the Queens hub of the LIRR. By now, we had learned that a second plane had hit the towers. The train crew had also learned about the unfolding events as they communicated on the train's PA system. The train continued west into Penn Station without incident about 20 minutes later, around 9:30 AM.
Nothing unusual was happening at Penn Station, and I made my walk to 6th Avenue to get the PATH train. I had a tote bag full of work stuff I at least wanted to drop off if that was all I could do that day. When I walked to 6th Avenue, I had a clear view of the north tower, about 3 miles due south, with smoke coming out of it (the first plane had struck on its north side). Manny pedestrians were standing around, watching it.
I entered the PATH station and got on a train to NJ and arrived about 15 minutes later without incident. I made the short walk to my office building but also saw the still-smoking north tower, now about 2 miles away, across the Hudson River. It was about 9:55 AM.
But when I entered my building, the lobby security staff was not allowing anyone to enter. Everyone had already evacuated the building.
I then returned to the PATH station to try to get back home, as there was nothing more for me to do in NJ. But just around that time, unbeknownst to me, they had begun locking down Manhattan. The NY-bound PATH train was rerouted to nearby Hoboken, where it discharged all of its passengers.
I wandered around Hoboken for a while, trying to figure out what to do next. Nearby ferries were not taking anyone but rescue workers into Manhattan. At a nearby parking lot, the attendant had a TV with the news on. The South tower had collapsed. I was now stranded in NJ.
I wandered around some more, trying to find a pay phone so I could call a coworker/friend who lived not too far away in Jersey City. I figured he would have returned home already (he drove to work). He was home and agreed to meet me not far from his place, as I couldn't quite remember where he lived. By now the second tower had collapsed.
We watched on TV for a while before going out for lunch. He had been away for the weekend so he had no food around. We hung out at his place the rest of the day as it took me a while to be able to make a call to my dad to let him know I was okay.
In the late afternoon, we watched in horror as Tower #7, the building we worked in for 10 years, collapsed after catching fire. At least nobody was in there when it went down.
I saw a news report that there was some ferry service running to midtown Manhattan so he drove me to the ferry location. But that report was false and I ended up walking back home to his place. He had gone off to visit other friends but his housemate was still around. I had some internet and email access, so I was able to let my online contacts know I was okay.
He returned home later and I crashed at his place overnight before walking back to Hoboken to get a PATH train to Manhattan and the LIRR home. I arrived at home at 8:45 AM, exactly 24 hours after I left. I left my tote bag with him so he could bring it to the office the next time he went back to the office.
I bought a newspaper at Penn Station which had a lot of stories, and I still have it today. I had a lot of phone messages at home, some from people I hadn't heard from in several years.
Over the next few weeks, I would learn about some close calls from people I knew, from a friend who missed a 9 AM breakfast meeting in the North tower only to be chased around the streets later from the collapsed tower's dust cloud, to a coworker who never made it to the office, being let off her express bus near the towers before they collapsed, later considering jumping into the river after the South tower went down (she is a better swimmer than runner). She fled to the Brooklyn Bridge to escape the dust cloud.
