I almost hate to do this... but let me start with my own 9/11 memory.
I was working in Cleveland at that time as a social worker. I was downtown with a client, helping them apply for some benefits on that day. I overheard some people in the welfare office talking about a plane crashing. There was some excitement among these individuals. I heard someone say something about a second plane crashing.
I was focused on helping my client with the situation at hand, and wasn't paying too much attention, but after a bit, I asked someone working at the office what was going on. He told me that a couple of planes had crashed in New York. I remember hearing something about military jets too. I assumed that the military screwed something up, and accidentally crashed a couple of their planes.
Before we left the building, we had heard about the hijacked planes crashing in New York. We had a rough idea about what was going on.
I would find out later that Flight 93 was in contact with Cleveland Air Traffic Control (and it was definitely in the area of Cleveland). AND, another plane that left Boston (NOT hijacked) landed in Cleveland over concerns that it may have been taken over too.
But..... man do I remember that day.
I think if you are old enough to REALLY remember that day, it STILL hits you hard.
So, while we were in New York, we had to visit the new 9/11 Memorial Museum.
We went through security, and it was similar to that at the airport, but the guy doing the screening was funny. He told a couple of young guys in front of me to take their belts off but to leave their pants on. The guys did not catch his remark but I told the Security guy I thought it was party time. It was a funny exchange. I thought it was nice that the guy doing security was trying to lighten the mood.
The church (St. Paul's) was there, which was very important during 9/11, it is now a museum kind of set up. That was interesting to see too.
I would have liked to have spent more time just exploring the area. The new One World Tower is beautiful, and the 9/11 memorial pools are very special.
