Some of you have proposed incorporating the 'Spirit' of Yamasaki in some structures (exterior walkway around the footprint of the two towers) was herein proposed.

If such would ever come to fruition it would not be a plesant solution because Yamasaki was the one who specified the use of so many Supplemental Energy Dissipation Devices. A total of 20,000 were holding up floor 10-110 each acting as bottom chord dampers in the floor trusses. These Viscoelastic dampers (3M) were at the heart of the catastrophic collapse of the towers! Their failure in the fire area and subsequent sheer failure in lower floors are WHY the building failed so quickly.

Any reminder of Yami's design, even in any 'whispy' way is like rubbing salt into our wounds. Like giving the builders of the Titanic another chance! Please pick some other 'mentor' for inspiration...perhaps even Frank Lloyd Wright, who NEVER would have signed off on the WTC steel bundled tube design or used an extraordinary number (20,000) viscoelastic dampers. So much for NY Port Authority's bargain building!

Studies are ongoing and new high rise specifications will undoubtedly damp down any 'blame' for the WTC collapse (we war against the terrorists, not Yamasaki), but my guess is that the hollow/bundled tube concept is very dead. Needless to say future floor trusses will not be held up by rubber grommets!

The concept that 'builds not' is the brightest so far. Back to the idea that satisifies the victims (we ALL are victims) requirement that no building be erected upon sacred ground. I agree! Further, I would like to see NO building on the site whatsoever i.e. all 15.64 acres left intact in grass. A central theme as I described earlier would be wonderful.
