We accidentally bought tickets here, thinking it was the memorial museum but I am SO glad we did. This was set up by the families, long before the city got the memorial museum up and running. It's touching, heartfelt, and hard. I felt very close to the families and victims in this space. The personal touch, plane tickets, jackets... pieces of the the lives lost there in front of you is very powerful and I recommend making the trip a few blocks from the site to see it. We were even able to hear the story of a survivor and what it was like to get out of the Trade Towers on that day. That, most of all, put this tragedy in a new perspective. I actually plan to go back and spend more time on the area's I was too saturated with information to absorb.
