What's the difference?  Those plates welded to the girder.  They are called stiffeners.

Why aren’t the stiffeners shown in the version above from the NIST report when they are shown in the actual WTC7 drawings? (NOTE:  I drew the stiffeners in because NIST failed to.)

Why the stiffeners are so important:
Stiffener plates are critically important.  They allow a girder to transfer loads to a wider footprint (bearing surface) and increase its ability to resist failure.

Lawyers for a Virginia man serving a life sentence for supporting jihad against the United States pushed Friday to pry more information out of the federal government about the possibility that cleric Anwar Al-Awlaki may have been recruited as a government informant a decade ago.

During a federal court hearing in Alexandria, Va., U.S. District Court Judge Leonie Brinkema didn't sound inclined to grant motions by former cancer researcher and Muslim scholar Ali Al-Timimi seeking more details on the government's relationship with Al-Awlaki, as well as other facts Al-Timimi's lawyers say were withheld prior to and during his 2005 trial on charges such as aiding the Taliban and soliciting treason.

The United States Secret Service--the law enforcement agency responsible for protecting the president and the White House--had a critical role to play in response to the terrorist attacks on September 11, 2001. Various accounts, however, reveal that it was inexplicably slow to react to the crisis that day. Secret Service agents only appear to have acted with the kind of urgency we might reasonably expect more than 45 minutes after the first plane crashed into the World Trade Center and more than 30 minutes after the second plane crashed.

The Secret Service's slow response meant some high-level individuals the agency was responsible for protecting were allowed to remain at unsafe locations throughout much of the duration of the attacks, and so could have been killed or seriously injured if their locations had been targeted.

The Secret Service was also alarmingly slow to protect the White House--a building considered a likely target for terrorists--which meant the people there, including some key government officials, were left in danger throughout the attacks. It only ordered the evacuation of the White House about an hour after the attacks began.

In this article, as well as examining the Secret Service's apparent failure to adequately protect the White House on September 11, we will look at the experiences of three individuals--Vice President Dick Cheney, his wife, Lynne Cheney, and National Security Adviser Condoleezza Rice--and consider how the Secret Service appears to have failed to sufficiently protect them.

On September 25th, 2013, the Dallas Observer, with a circulation of over 77,000, published an article about the ReThink911.org billboard located on southbound Stemmons Freeway (I-35) near the Oak Lawn exit.

Dallas Gets It Very Own 9/11 Truther Billboard on Stemmons Freeway

You had to know that the World Trade Center attacks on September 11, 2001, would spawn a host of conspiracy theories, like the assassination of President John F. Kennedy and Pearl Harbor before it. So, we here at the Dallas Observer office weren't all that surprised to receive multiple hand-mailed letters from the Architects & Engineers for 9/11 Truth, informing us that its campaign to expose the real story behind the fall of the Twin Towers had come to the City of Hate, on a nearby stretch of Stemmons Freeway between Oak Lawn and Market Center.
