It might sound silly, but given the vulnerabilities of these buildings, would this work?
IF towers over 100 stories tall are going to be built, would it be possible to put a 'no go zone' for aircraft around these buildings?
Could the AirForce/Army therfore operate a SAM batter on the roof of one of these buildings?
Would a SAM battery have saved the WTC?
Just wondering...as they are talking about rebuilding the WTC with even taller buildings (Good idea in my book).
