This is the facade at the top of the World Trade Center. This model features a portion of floors 104-108. Floors 104-105 were office floors; floors 106-107 was the Windows on the World restaurant; floors 108-109 were mechanical floors; and floor 110, also known as the roof, hosted a broadcasting system, which included a 306-foot (110 m) telecommunications antenna. Feel free to use this for any of your WTC models. It's not 'stealing' by me. Enjoy!
