I'm glad that Linda Carbonella Victoire's letter (June 14) expresses respect for Architects and Engineers for 9/11 Truth. The media blackout of the 9/11 truth movement, which includes hundreds of highly credentialed Americans, has resulted in a disproportionate amount of misinformation. Professional people who have pointed out logistical problems with the official story of 9/11, because of the conspiracy theorist label, have done so at the risk of losing their credibility or their livelihood.
The 1970 documentary film "Building the World Trade Center" shows clearly that the buildings' primary support was not "their central elevator shaft" but 47 massive steel core columns, and that these columns were in fact anchored firmly to the bedrock. The perimeter columns were over-designed by 2000 percent. The tower's tube design provided superior resistance to lateral forces and became the standard for skyscrapers since the 1960s, including the Sears Tower. The WTC's lead engineer John Skilling said the towers could survive both the impact of a 707(cruising faster than today's 767) and the resulting jet fuel fire.
On 9/11 not only did the intact structures below the impact zones ultimately fail to resist the shifted loads from the damaged columns, they provided zero resistance, since the towers fell at virtually free-fall speed with perfect symmetry. Building 7, which was not hit by a plane, also collapsed in this manner.
So these would have been the three worst engineering failures in modern history, calling into question the safety of hundreds of similarly designed buildings. So why was there not the forensic investigation necessary to determined exactly how the buildings failed? The answer is that these were not structural failures but highly sophisticated controlled demolitions. This is the suspicion of virtually all of the architects and engineers who have been shown the footage of the Building 7 collapse.
