I watched it a few times and was going to post a thread on here but just didn't. That was one of the best documentaries about the Trade Center and everyone involved. I am amazed and very happy that they kept the original footprints/lower level of the towers and converted them to waterfalls. The museum is beyond anything that I would have expected with the entire fleet of emergency vehicles that was damaged, original steel skeleton reconstructed, as well as the personal belongings of victims. The most amazing thing is the base of tower 1 with the "explosion proof" walls.
