Comment: Actually...

(See in situ)


It was not me who carried out the analysis or made the comments I have presented you with, it was merely the structural engineers who actually designed, built and maintained the World Trade Center Towers!

But as you appear to regard other sources as more reliable I will answer your new question with a quote from the NIST report:

Federal Building and Fire Safety Investigation of the World Trade Center Disaster.

Baseline Structural Performance and Aircraft Impact Damage Analysis of the World Trade Center Towers

NIST found a three page white paper that mentioned another aircraft impact analysis, involving impact of a jet at 600 mph (970 km/h), was indeed considered.

Unfortunately, just like Mr Demartini, the original documentation of the study was lost when Port Authority offices were destroyed in the collapse of the World Trade Center.

This is Finding 11 of that report:

NIST NCSTAR 1-2, WTC Investigation cix

Executive Summary

Finding 11:

Documents from The Port Authority of New York and New Jersey indicated that the safety of the WTC towers and their occupants in an aircraft collision was a consideration in the original design.

The documents indicate that a Boeing 707, the largest commercial aircraft at the time, flying at 600 mph was considered, and the analysis indicated that such collision would result in only local damage which could not cause collapse or substantial damage to the building and would not endanger the lives and safety of occupants not in the immediate area of impact.

No documentary evidence of the aircraft impact analysis was available to review the criteria and methods used in the analysis of the aircraft impact into the WTC towers, or to provide details on the abihty of the WTC towers to withstand such impacts.
