Another interesting tidbit about 1 WTC...The views from the indoor observation deck when finished will surely be amazing, I believe during Discovery Channel's "Rising: Rebuilding Ground Zero" they mentioned that the windows on the floors will be expansive and offer wide angle views, unlike in the old Twin Towers, which had very narrowly-spaced windows, which supposedly to add a sense of security due to Yamasaki's fear of heights. Each window in the old Towers were only shoulder-length in width. New 1 World Trade will have much wider views, I believe.
