Watching documentaries about 9/11

Hearing some of the phone calls, and hearing people (relatives) speak about it who have never spoken about it before.

It's from 2 years ago.

It was one guys last day at work. He was just coming to clear his office and got trapped.

Another lady was just gonna be there for 1 day to do a presentation and got trapped.

They played a message a guy left for his family, stating that he is alive and well, because his building didn't get hit.
His building was the second one to get hit, 17 minutes later.

20 years later and its still unbelievable
