9/11 Inside Job: Building 7, Larry Silverstein, the Dancing Israelis

Q: Why did Building 7 collapse on 9/11?

World Trade Center 7 — a 47-story office building roughly 350 feet north of the Twin Towers — collapsed at 5:20 PM on September 11, 2001, approximately seven hours after the Twin Towers. It was not hit by an aircraft. The official explanation, published by NIST in its 2008 final report, attributes the collapse to thermal expansion of girders caused by unfought office fires — the first and only documented case of a steel-framed high-rise collapsing from fire alone. Architects & Engineers for 9/11 Truth — founded in 2006 by architect Richard Gage — have argued the collapse exhibits characteristics consistent with controlled demolition and that NIST's model is unable to replicate the observed free-fall acceleration during the collapse's first 2.25 seconds.

Q: What did Larry Silverstein mean by 'pull it'?

In the September 2002 PBS documentary 'America Rebuilds,' Larry Silverstein — leaseholder of the World Trade Center — said: 'I remember getting a call from the, uh, fire department commander, telling me that they were not sure they were gonna be able to contain the fire, and I said, "We've had such terrible loss of life, maybe the smartest thing to do is pull it." And they made that decision to pull and we watched the building collapse.' Silverstein has subsequently said he meant 'pull the firefighting operation.' Critics note that 'pull it' is demolition-industry shorthand for initiating demolition and that the statement — if it meant demolition — is inconsistent with the official NIST fire-collapse explanation.

Q: When did Larry Silverstein buy the World Trade Center?

Larry Silverstein signed the 99-year net lease for the World Trade Center on July 24, 2001 — 48 days before the September 11, 2001 attacks. The deal was for $3.2 billion. The lease included terrorism insurance coverage of $3.55 billion per occurrence. After the attacks, Silverstein argued in court that the two plane impacts constituted two separate events rather than one, and in 2007 was awarded a $4.55 billion insurance settlement — the largest in US history at the time.

Q: Who are the Dancing Israelis?

On September 11, 2001, shortly after the first plane hit the World Trade Center, five Israeli men were seen by a New Jersey resident filming and reacting to the attack from the parking lot of the Doric Towers apartment building in Union City, NJ. The witness described them as 'jovial,' giving high-fives, smiling, and hugging. She reported them to police. They were arrested four hours later. The men worked for Urban Moving Systems, a New Jersey moving company whose owner, Dominik Suter, subsequently fled to Israel. The FBI reportedly assessed Urban Moving Systems as a Mossad front (per a 2002 Forward article citing a former official). The five men were detained for approximately two months, then deported to Israel without charges. They subsequently appeared on Israeli television describing themselves as 'documenting the event.'

Q: Was Larry Silverstein in the World Trade Center on 9/11?

No. Silverstein typically ate breakfast at the Windows on the World restaurant on the 107th floor of the North Tower each morning. On September 11, 2001, his wife insisted he attend a previously scheduled dermatology appointment. His daughter Lisa and son Roger — who also regularly worked in the buildings — were reportedly absent that morning as well. Silverstein has described the appointment and his survival in interviews; the absence of his adult children from the buildings on the morning has been cited by 9/11 researchers as notable.

Q: What did the BBC report about Building 7?

On September 11, 2001, at approximately 4:57 PM Eastern Time, BBC World reporter Jane Standley reported on-air that the Salomon Brothers Building — which was Building 7 — had collapsed. WTC 7 did not actually collapse until 5:20 PM, approximately 23 minutes later. The broadcast footage shows Standley reporting the collapse with WTC 7 clearly visible, still standing, in the background behind her. The BBC has acknowledged the incident and attributed it to confusion in a fast-moving news environment; the tape of the original broadcast was reportedly lost. The segment remains one of the most-cited data points in 9/11 inside-job research.

Q: What did firefighters say about bombs on 9/11?

In August 2005, following a four-year lawsuit by the New York Times and families of 9/11 victims, the City of New York released approximately 12,000 pages of oral-history interviews with 503 FDNY firefighters, medics, and other personnel. Conducted in late 2001 and early 2002, the testimonies include dozens of firsthand accounts describing explosions, secondary blasts, and sounds consistent with demolition — including in the lobbies and basements of the towers. FDNY firefighter Louie Cacchioli: 'I think there were bombs set in the building.' EMT Patricia Ondrovic described explosions. Chief Frank Cruthers described 'multiple secondary explosions.' The oral histories are publicly available and have been widely analyzed by independent 9/11 researchers.

Q: Did the Simpsons predict 9/11?

The September 21, 1997 episode 'The City of New York vs. Homer Simpson' contains a frame in which the number '9' appears on a pamphlet in front of an image of the Twin Towers, arranged to read '9/11' when viewed together. The episode aired four years before the attacks. The Simpsons producers have addressed the scene as coincidence involving New York-specific numerology (the Nineteenth Amendment, the 91 Express bus, etc.). Hoax-detection researchers broadly agree the scene is a genuine Simpsons episode and a genuine frame, while disputing whether the arrangement reflects anything beyond visual coincidence.

Most of the evidence cited in the 9/11 inside-job case is not secret. It is on the Congressional record, in released FOIA documents, in court transcripts, and in television footage that aired live. What is contested is not whether these pieces of evidence exist, but what pattern they form when assembled.

Where it started

On the morning of September 11, 2001, four US commercial aircraft were hijacked. Two struck the North and South towers of the World Trade Center in New York. One struck the Pentagon. One crashed in Pennsylvania. Nearly 3,000 people were killed. The North Tower collapsed at 10:28 AM, the South Tower at 9:59 AM. A third building — World Trade Center 7, a 47-story office building that was not hit by any aircraft — collapsed at 5:20 PM. The official account, produced by the 9/11 Commission (2002–2004) and subsequent NIST investigations (2005 for the towers, 2008 for WTC 7), attributed the attacks to al-Qaeda under Osama bin Laden, operationalized by 19 hijackers, and the subsequent collapses to fire and structural damage.

The inside-job framing has been advanced by multiple groups including Architects & Engineers for 9/11 Truth (founded 2006 by Richard Gage, now comprising over 3,000 architects and engineers), the 9/11 Family Steering Committee's surviving members, and a substantial body of independent researchers and journalists. The framing is not one unified theory but a cluster of documented questions that researchers argue the official investigation inadequately addressed.

What the theory claims

The inside-job framing does not converge on a single actor. Its specific framings:

LIHOP (Let It Happen On Purpose). Elements of the US government had advance warning of the attacks and allowed them to proceed. Citations include the August 6, 2001 Presidential Daily Brief ("Bin Laden Determined to Strike in US"), multiple FBI and CIA whistleblower accounts, and pre-attack financial anomalies.
MIHOP (Made It Happen On Purpose). Elements of the US government actively orchestrated the attacks through facilitation, explosive planting, or drone substitution for the aircraft. Citations focus on Building 7 collapse characteristics, the Pentagon strike geometry, and the pre-attack positioning of key figures.
Allied-state framing. Intelligence services of allied states (most commonly Israel or Saudi Arabia) had advance knowledge or operational involvement. Citations include the Dancing Israelis incident, the Odigo warnings, the 28 pages redacted from the Congressional Joint Inquiry (released 2016, detailing Saudi government connections to the hijackers), and the Netanyahu 2008 statements.
Controlled demolition framing. One or more of the WTC buildings were brought down by pre-placed explosives rather than by the aircraft impacts and fires alone. Citations include FDNY oral histories, the Building 7 free-fall finding, molten-steel observations, and Architects & Engineers for 9/11 Truth's structural analysis.

The variations

Within the 9/11 research community, the LIHOP and allied-state framings are the most widely held. The controlled-demolition framing focuses specifically on Building 7 among a subset of researchers; a smaller subset extends it to the Twin Towers. The hardest variations — drone substitution, hologram theories, no-plane-at-Pentagon — are held by a minority and disputed within the research community itself. What the variations share is the argument that the 9/11 Commission Report represents an incomplete — possibly deliberately incomplete — account. The Commission's own chair and vice-chair (Thomas Kean, Lee Hamilton) later publicly stated that they believed they had been lied to by NORAD and by the FAA during the investigation.

What researchers point to

Documented · the lease and insurance

Larry Silverstein signed the 99-year net lease for the World Trade Center on July 24, 2001 — 48 days before the September 11 attacks — for $3.2 billion. The lease included $3.55 billion in terrorism coverage per occurrence. Silverstein successfully argued in court that the two plane impacts constituted two separate events; in 2007 he was awarded a $4.55 billion insurance settlement, the largest in US history at that time. The towers had substantial known asbestos contamination — approximately 400 tons of spray-on fireproofing — whose legally mandated removal was estimated at over $1 billion. Silverstein was not in the buildings on the morning of 9/11 due to a dermatology appointment his wife had scheduled; his adult children Lisa and Roger were also reportedly absent.

Documented · "pull it"

In the September 2002 PBS documentary America Rebuilds, Silverstein said of Building 7: "I remember getting a call from the, uh, fire department commander, telling me that they were not sure they were gonna be able to contain the fire, and I said, 'We've had such terrible loss of life, maybe the smartest thing to do is pull it.' And they made that decision to pull and we watched the building collapse." Silverstein has subsequently clarified he meant "pull the firefighters." 9/11 researchers have argued that "pull it" is demolition-industry shorthand for initiating a controlled demolition, and that a controlled demolition of a 47-story steel-framed high-rise with no pre-wiring is physically impossible to execute in the time frame suggested — implying that pre-placed demolition infrastructure must have existed.

Documented · the BBC early report

At approximately 4:57 PM Eastern Time on September 11, 2001 — 23 minutes before WTC 7 actually collapsed — BBC World reporter Jane Standley reported on air that the Salomon Brothers Building (WTC 7) had collapsed. Footage of the broadcast shows WTC 7 clearly standing behind her. The BBC has acknowledged the early report, attributed it to newsroom confusion, and acknowledged that the original broadcast master tape was subsequently lost. The remaining footage was preserved from off-air recordings and remains the single most-cited visual piece of evidence in Building 7 research.

Documented · the FDNY oral histories

In August 2005, following a multi-year lawsuit by the New York Times and 9/11 families, the City of New York released approximately 12,000 pages of oral-history interviews with 503 FDNY firefighters, paramedics, and personnel, conducted in late 2001 and early 2002. Multiple testimonies describe explosions, secondary blasts, and sounds consistent with demolition. FDNY firefighter Louie Cacchioli: "I think there were bombs set in the building." EMT Patricia Ondrovic, Chief Frank Cruthers, and dozens of others describe similar observations. The full archive is publicly searchable via nytimes.com's WTC histories page.

Documented · the Dancing Israelis

On the afternoon of September 11, 2001, five Israeli men — employees of Urban Moving Systems, a New Jersey company owned by Dominik Suter — were arrested after being seen by a New Jersey resident filming and celebrating the WTC attacks from the parking lot of the Doric Towers apartment building in Union City. A 2002 article in the Forward cited a former government official describing the FBI's assessment that Urban Moving Systems was a Mossad front. Suter fled to Israel. The five were detained approximately two months and deported to Israel without criminal charges. They subsequently appeared on Israeli TV; one said: "Our purpose was to document the event." The FBI's official post-investigation position was that the men had no advance knowledge. Congressional pressure reportedly influenced their release.

Documented · the Netanyahu quote

In a 2008 recorded conversation with settlers in the West Bank, Israeli politician Benjamin Netanyahu was captured on video saying: "We are benefiting from one thing, and that is the attack on the Twin Towers and Pentagon, and the American struggle in Iraq." He continued that the attacks had "swung American public opinion in our favor." The recording was released in 2010. The video is authentic; Netanyahu has not disputed its contents. Interpretations range from cynical political commentary on geopolitical side-effects to direct implication of advance-benefit knowledge.

The official position

The 9/11 Commission Report (July 2004) and subsequent NIST investigations hold that the attacks were planned and executed by al-Qaeda under Osama bin Laden, that 19 hijackers operationalized the attacks, that the Twin Towers collapsed due to aircraft impact damage and subsequent fire, and that WTC 7 collapsed due to thermal expansion of girders caused by fire. The Commission's final report declined to investigate several specific questions raised during hearings. The US has never charged any US or allied-state actor with involvement. Bin Laden was killed by US Navy SEALs in Pakistan on May 2, 2011. The 28 redacted pages of the Congressional Joint Inquiry, released in 2016, detailed connections between the hijackers and Saudi government figures but did not result in formal charges.

Where it is now

Twenty-five years after the attacks, the 9/11 questions remain substantially active in independent research. The May 2023 federal subpoena of the Saudi government regarding 9/11-related information has produced new document releases. Architects & Engineers for 9/11 Truth continues to maintain its membership and publish structural analysis. The University of Alaska Fairbanks' 2020 Hulsey Report — a four-year computer simulation of WTC 7's collapse — concluded that fire could not have caused the collapse, directly contradicting NIST's 2008 finding. The report has not been formally responded to by NIST. Calls for a new 9/11 investigation continue, without formal federal response.

Frequently asked questions

What is the 9/11 inside job theory?

The umbrella theory that elements of the US government — or of allied governments — had advance knowledge of, facilitated, or orchestrated the 9/11 attacks beyond the 9/11 Commission account. The theory's specific framings branch into LIHOP, MIHOP, allied-state, and controlled-demolition variants.

Why did Building 7 collapse on 9/11?

WTC 7 collapsed at 5:20 PM on September 11, 2001 — seven hours after the Twin Towers, and without being hit by any aircraft. NIST's 2008 final report attributes the collapse to fire-induced thermal expansion. Architects & Engineers for 9/11 Truth and the 2020 UAF Hulsey Report argue the collapse characteristics are incompatible with fire alone.

What did Larry Silverstein mean by "pull it"?

On the 2002 PBS "America Rebuilds" documentary, Silverstein described discussing Building 7 with a fire commander and saying "maybe the smartest thing to do is pull it." Silverstein has clarified he meant "pull the firefighters." Researchers note "pull it" is demolition-industry shorthand and that a controlled demolition without pre-wiring is not possible in the relevant time frame.

When did Larry Silverstein buy the World Trade Center?

July 24, 2001 — 48 days before September 11. A $3.2 billion 99-year lease with $3.55 billion per-occurrence terrorism insurance. Silverstein won a $4.55B settlement in 2007 by arguing the two impacts were separate events.

Who are the Dancing Israelis?

Five Israeli men — employees of Urban Moving Systems — arrested September 11, 2001 after being seen filming and celebrating the WTC attacks from New Jersey. Urban Moving Systems was reportedly assessed by the FBI as a Mossad front. Detained approximately two months, deported to Israel without charges.
