The ASCE's Pentagon Building Performance Report:
Arrogant Deception — Or an Attempt to Expose a Cover-up?

By Sami Yli-Karjanmaa

This article looks at The Pentagon Building Performance Report (January 2003) by the American Society of Civil Engineers (available on the internet). The key conclusion reached is that the Report fails in its attempt to show that the structural damage caused to the Pentagon on Sept. 11, 2001 was caused by a crash by a Boeing 757 aircraft. The main purpose of the Report seems therefore to be to back the official, untruthful story about the events of 9/11. However, part of the inconsistencies are so glaring that an intention of sabotaging the said main purpose cannot be excluded.

The key conclusion is based on nine observations which can be divided into two categories based on whether they concern events prior to or during the crash of the aircraft. As regards the first group, the overall conclusion is that the approach of the aircraft and its being damaged cannot have taken place in the the manner put forward in the Report. This conclusion is supported by the following observations:

For the second group, the overall conclusion is that the Report's description of the impact of the plane and of the damage caused manifestly contradicts photographic evidence from the scene. The description includes impossible, contradictory and unexplained phenomena:

The uncertainties related to the alleged point of impact as well as the approach angle, vertical position and inclination of the aircraft do not weaken the conclusion presented herein that the Pentagon could not have been hit by a Boeing 757 in the manner described in the report. This is because changing one of these factors to allow the better explanation of a particular damage (or the lack of it) renders the other damage even less comprehensible.

NB. This author is aware of theories promoted to suggest that the Pentagon was indeed hit by a Boeing 757 which was destroyed before it (or all of it) hit the building. While this possibility cannot be excluded offhand — and the conclusions about the impossibility of a B-757's crash reached in this article may not be directly applicable to such a case — no substantial evidence has so far been produced to back up such a theory.
