A Special Federal Grand Jury has been convened to hear evidence. which was never addressed, and witnesses who were not included in the 9/11 Commission Report. The evidence was omitted over the objections of victim family members such as Bob McIlvaine. McIlvaine's son Bobby was killed in the lobby of WTC1 by an explosive force which shattered thick construction-grade glass, and demolished the lobby. McIlvaine maintains this could not have been caused by "fireballs" of kerosene, the central component of jet fuel, coming down the elevator shafts, as the 9/11 Commission concluded.

McIlvaine, other family members, and a consortium of architects, engineers, and other scientists and technical experts maintain that the pattern of destruction of three skyscrapers on 9/11 indicates that they were destroyed by controlled demolition, using pre-planted explosives and incendiaries.

More than a dozen 9/11 family members who either have not signed settlement agreements which prohibit public discussion of the attacks, or have chosen to ignore them, are spearheading an effort with volunteer attorneys to challenge the 9/11 Commission's conclusion that the strikes on the Twin Towers by two commercial aircraft initiated a chain of events which resulted in the total destruction of three skyscrapers in lower Manhattan, World Trade Centers One and Two, and World Trade Center Seven.

WTC 7 was never hit by a plane, yet it collapsed in a first-ever instance of a construction faulty enough to bring the tower down in a perfectly symmetrical manner, into its own footprint, in seven seconds.

The New York State's Attorney's Office for the Southern District of New York has not yet scheduled a date for proceedings to begin. However, the State's Attorney's Office says that a Grand Jury has been convened.

In a 58-page filing, accompanied by 57 exhibits, with the US Attorney for the Southern District of New York, evidence which the Lawyers' Committee for 9/11 Inquiry is calling for, which it says was never accounted for in the 9/11 Commission Report, includes:

- The testimony of first responders, such as firefighters, and other witnesses, that sequential explosions running down the height of the buildings from top to bottom, accompanied by bright "flashes" in patterns of "belts" around the perimeters of the buildings were seen and heard.

- The presence of residue in the dust, which was never addressed by the 9/11 Commission, which indicates the presence of high explosives and high-temperature incendiaries. The Lawyers' Committee criticizes the 9/11 Commission statement that no evidence of explosives were found as meaningless, since no testing for explosives was ever performed.

- The analysis by a French geophysicist in 2012 of seismic data from Lamont-Doherty Earth Observatory at Columbia University, from which he draws the conclusion that "the three buildings were demolished by a controlled process."

- The announcement by the BBC that WTC7 had collapsed one-half hour before it actually did, while it stood in plain view on live television behind BBC announcer Jane Standley, and what the Lawyers' Committee considers the unsatisfactory explanation of the BBC attributing the oddity to an "error."

- Evidence of explosions in the lower levels of the North Tower even before the first plane hit, including the testimony of the head janitor William Rodriguez, who was honored at the White House by George W. Bush for his heroic actions that day.

In a supplement to the complaint with the short title "Persons with Material Information," in which many names have been redacted in the public version of the document in order to protect the Special Grand Jury process, the Lawyers' Committee seeks to call for witness testimony including:

- WTC security staff who have reported that in the weeks prior to 9/11, work crews came in to perform work late at night but were not required to sign in as required by established security policies, nor required to be accompanied by security staff members as required by established security policies.

- Persons who observed "power down" incidents in the weeks before 9/11, during which all security systems and cameras would have been disabled.

- An elevator company which was contracted to perform a massive "elevator modernization" in the nine months prior to 9/11, which the Committee contends is of special interest because access to the WTC elevator shafts would have also provided access to the main structural components, the core columns and beams, in the WTC towers.

- An "organization," which included many high-level defense department officials in the Bush administration, which was publicly recommending the invasion of Iraq long before 9/11. The unnamed organization, which can only refer to the Neoconservative think tank The Project for a New American Century, wrote in a policy paper that it would take a "new Pearl Harbor" to motivate the American people to undertake the commitment of money and troops needed for the US to assert its military power to maintain global dominance over the coming century. Project for a New American Century's Bush administration members included Kenneth Adelman, John Bolton, Dick Cheney, Zalmay Khalilzad, Richard Perle, Donald Rumsfeld, Paul Wolfowitz, and former Pentagon Comptroller Dov Zakheim.

- Five Israeli nationals who were arrested on 9/11 after being observed filming the attacks from a particularly strategic location, and celebrating and "high-fiving," whose van tested positive for the previous presence of explosives. Two of the men, it was reported by the New York newspaper The Jewish Weekly Forward, had been determined by the FBI to be Israeli Mossad agents. Mossad is the Israeli secret service equivalent of the CIA.

In addition, the FBI report on the detainees shows that the group had scouted out the location for the filming of the attacks on the day before, on September 10th, and posed as "construction workers" at the apartment building nearby. According to the FBI, one of the arrestees stated to the FBI that one of his co-workers told him "they are taking down the second building" on the morning of 9/11. Also found on the men at the time of their arrest was a WTC visitor card, large amounts of cash, and multiple passports and airline tickets for various destinations around the globe. Finally, a phone number was found on one of the arrestees which corresponded to a moving company which the FBI's Miami office determined had been used by one of the alleged 9/11 hijackers. One of the photos developed by the FBI of seized film shows one of the men flicking a cigarette lighter in front of the smoldering ruins of the WTC.

- Persons with knowledge of the decision to evacuate the NYC Emergency Operations Center in WTC 7 before the collapse of the first tower, including Mayor Rudy Giuliani. WTC7 itself collapsed later that afternoon, in what was positively identified as a demolition by world demolition expert Danny Jowenko, who in 2011 died in a single-car accident when he crashed into a tree on a Sunday morning on his way to church.

- Persons who were involved in making stock trades just prior to 9/11 which predicted a sudden plunge in the stock price of American Airlines.

- Persons with control over the immediate destruction of 99.5% of the steel evidence of the destroyed buildings, against the Fire and Explosion Guidelines of the National Fire Protection Association, which requires testing for explosives anytime there is evidence of "high-order damage" or "the shattering of the [steel] structure." The steel was loaded onto barges and shipped to China and India, where it was melted for other uses.

- Scientific and technical experts in the fields of high-rise architecture, structural engineering, metallurgy, and demolitions.

The Lawyers' Committee at numerous points in the documents filed stress that any identification of persons in the petition should not be taken as "an indication that such persons are alleged by the Lawyers' Committee to have been a perpetrator or to have been a suspect in regard to the federal crimes reported by the Lawyers' Committee."

Immediately after the attacks, Osama bin Laden denied any involvement with them. Some have challenged the authenticity of later videotapes in which men purported to be bin Laden take responsibility for the attacks.

In a press release the Lawyers' Committee contends that "the evidence permits no other conclusion, as a matter of science, as a matter of logic, as a matter of law" than that the three WTC buildings which were destroyed on 9/11 were felled by controlled demolition.
