Sounds like a red-herring to me. A number of architects and structural engineers have noted the solidly robust design of the Towers, with unusually massive vertical supports--both in the core, and on the perimeter, designed to withstand aircraft collision, and seismic and hurricane activity. In diagrams provided by the official report (and “Mechanics Illustrated,” e.g.), these supports are frequently omitted. "911 Mysteries" and "Loose Change" provide lots of good commentary and facts. Then, the new "9/11: Explosive Evidence" features a selection of the 1500 “Architects and Engineers for 911 Truth” members--seasoned professionals with impeccable credentials--who insist that the official account is as reliable as reports of an imminent visit by the Good Tooth Fairy. This film is solid science, not speculation, nor rant, and the testimony of architects, structural engineers, demolition experts, and physicists is convincing. The supporters of the official report are reduced to apologists, and advocates for pseudoscience. The Report has now been debunked.

KPFA; You guys rock!!!

An endless discussion is taking place about how the World Trade Center came down but no attention is paid to how it went up.
Several years ago the New Yorker magazine published an article about the men who built and maintain the Verazzano bridge which connects Brooklyn, Staten Island and New Jersey.
Some of those men also worked on the Twin Towers. They considered the workmanship and materials use4d in thier construction substandard, mentioning the girders and the joints that connected them as inferior and describing the towers as hollow shells, expressing no surprise at the way they came down,
By way of contrast consider the Empire State building.
In the 1940s {i dont remember the year} a B29 bomber {the famous flying fortress} was flown,one foggy morning {due to pilot error} into that building.
The only injury in the building was {miraculously} a woman who was in an elevator that fell when the cables were snaped
The people on the floors below did not even know that a plane had crashed into the building.
