Its one of the few things where I remember where I was when it happened. There was talk about a plane hitting a building in New York at my last call, having over an hour's drive back to the depot I put Radio 4 on, & heard about the 2nd plane crash, then both towers collapse. ******* Hell! Put the News on at home, saw the remains of the plane that crashed into the Pentagon & reports of a plane crash (which was intended for the White House) 14 Years later, I still remember it like it was yesterday. Watching it all unfurl was surreal in a horrifying way.
It's one of my things to do on my Bucket List, go & pay my respects at some point.
I did the same thing when Princess Diana was Killed, I went & paid my respects at Buckingham Palace & Kensington Gardens.
