From a fellow engineer (Aerospace by job description and Mechanical by education):
[b][i]The owner of the WTC doesn't want to build them again that big, but I think that is a mistake in two fronts:
- It would be a perpetual symbol of terrorism victory over America.
- A building this tall can be the best place to defend the rest of New York City.
I think that to protect the next edition of the World Trade Center Twin Towers two things should be done:
1 - Double the number of columns, from the 4 corner columns it had before to 8, the new ones being inside the building.
2 - Put an Aegis Radar and Missile Battery on top of one of the towers. An Aegis Radar and Missile Battery can handle 100 simulataneous air targets, and it would provide complete Air Cover Protection to Manhattan and outliying boroughs. With some modifications it can even provide protection from nuclear missile threat from "rogue nations".
