Modern Marvels - Season 8 Episode 19 The World Trade Center
7.93 44 minutes An historical look at the technological engineering of the World Trade Center. The special was completed and the interviews took place before the tragic events of September 11, 2001. Rather than remake the program to reflect the horrors of that day, our program stands as an historical record to the wonder it once was–from the construction of this technological feat to the daily working of its complex system. The program offers some of the last interior footage of the Twin Towers.
