"Changes during construction led to a finished product that was structurally unsound. In 1978, prompted by a question from a student, LeMessurier discovered a potentially fatal flaw in the building's construction: the skyscraper's bolted joints were too weak to withstand 70-mile-per-hour (113 km/h) wind gusts at specific angles.
"While LeMessurier's original design and load calculations for the special, uniquely-designed 'chevron' load braces used to support the building were based on welded joints, a labor and cost-saving change altered the joints to bolted construction after the building's plans were approved.
"For the next three months, a construction crew welded two-inch-thick steel plates over each of the skyscraper's 200 bolted joints during the night, after each work day, almost unknown to the general public."

Truthers are always running their mouths, "How could anyone plant charges into a building without anyone noticing?"

Good discussion thread.
Note that welding steel plates to joints would be very similar to placing explosives at/near/on the joints.

And oh yeah, would these be the hush-a-boom explosives again?

I worked in demolition from 2002 to 2007. We would do work in schools, malls, office buildings, government buildings, and factories. Many times, we would be working in one section of the building, while the other parts were still occupied. I never once was asked for credentials, or questioned about my presence(most people wouldn't even make eye contact and/or acknowledge my existence).
As long as you have a pair of dickies and a hard hat, you can walk around nearly anywhere practically unnoticed(and before you wonder if i'm just a forgettable type of person, i am 6/3, with long hair, not exactly the blend into the background kind of guy). Every time i hear someone say that someone would have noticed this activity i laugh.
In the malls, and some of the buildings, we had to work at night due to noise complaints. We would come in after all employees had left, had our own keys, and would clean up and leave before the first employee showed up. I am pretty sure that my crew could have accomplished that which so many people say is impossible, and probably in a shorter time than most would believe.

i dont think you have proved your point that it could have been done without anybody noticing that something was going on. some one would.

So a building was built, completed and occupied and it had fatal structural flaws...hmmm.
I wonder if the WTC's had a similar problem which brought them down after the plane impacts and fires????
