There you go chum, all the answers you need:

For instance:
1. If the World Trade Center (WTC) towers were designed to withstand
multiple impacts by Boeing 707 aircraft, why did the impact of
individual 767s cause so much damage?
As stated in Section 5.3.2 of NIST NCSTAR 1, a do***ent from the ****t
Authority of New York and New Jersey (PANYNJ) indicated that the impact
of a [single, not multiple] Boeing 707 aircraft was analyzed during the
design stage of the WTC towers. However, NIST investigators were unable
to locate any do***entation of the criteria and method used in the
impact analysis and, therefore, were unable to verify the assertion that
“… such collision would result in only local damage which could not
cause collapse or substantial damage to the building.…”
The capability to conduct rigorous simulations of the aircraft impact,
the growth and spread of the ensuing fires, and the effects of fires on
the structure is a recent development. Since the approach to structural
modeling was developed for the NIST WTC investigation, the technical
capability available to the PANYNJ and its consultants and contactors to
perform such analyses in the 1960s would have been quite limited in
comparison to the capabilities brought to bear in the NIST investigation.
The damage from the impact of a Boeing 767 aircraft (which is about 20
percent bigger than a Boeing 707) into each tower is well do***ented in
NCSTAR 1-2. The massive damage was caused by the large mass of the
aircraft, their high speed and momentum, which severed the relatively
light steel of the exterior columns on the impact floors. The results of
the NIST impact analyses matched well with observations (from photos and
videos and analysis of recovered WTC steel) of exterior damage and of
the amount and location of debris exiting from the buildings. This
agreement sup****ts the premise that the structural damage to the towers
was due to the aircraft impact and not to any alternative forces.
2. Why did NIST not consider a “controlled demolition” hypothesis with
matching computer modeling and explanation as it did for the “pancake
theory” hypothesis? A key critique of NIST’s work lies in the complete
lack of analysis sup****ting a “progressive collapse” after the point of
collapse initiation and the lack of consideration given to a controlled
demolition hypothesis.
NIST conducted an extremely thorough three-year investigation into what
caused the WTC towers to collapse, as explained in NIST’s dedicated Web
site, http://wtc.nist.gov.
This included consideration of a number of
hypotheses for the collapses of the towers.
Some 200 technical experts—including about 85 career NIST experts and
125 leading experts from the private sector and academia—reviewed tens
of thousands of do***ents, interviewed more than 1,000 people, reviewed
7,000 segments of video footage and 7,000 photographs, analyzed 236
pieces of steel from the wreckage, performed laboratory tests and
sophisticated computer simulations of the sequence of events that
occurred from the moment the aircraft struck the towers until they began
to collapse.
Based on this comprehensive investigation, NIST concluded that the WTC
towers collapsed because: (1) the impact of the planes severed and
damaged sup****t columns, dislodged fireproofing insulation coating the
steel floor trusses and steel columns, and widely dispersed jet fuel
over multiple floors; and (2) the subsequent unusually large jet-fuel
ignited multi-floor fires (which reached temperatures as high as 1,000
degrees Celsius) significantly weakened the floors and columns with
dislodged fireproofing to the point where floors sagged and pulled
inward on the perimeter columns. This led to the inward bowing of the
perimeter columns and failure of the south face of WTC 1 and the east
face of WTC 2, initiating the collapse of each of the towers. Both
photographic and video evidence—as well as accounts from the New York
Police Department aviation unit during a half-hour period prior to
collapse—sup****t this sequence for each tower.

So the answera are out there. people like you just don't want to know.
You want to think that such a large scale conspiracy, involving active
wortk that would take years to complete from hundreds of mainstream
people is "done" is there, and that's that.
I say if you can't *get* the "answers" then go be stupid somewhere else.
