Key Official 9/11 Public Reports#

These government-authored reports are the foundational public records of the 9/11 attacks and their immediate aftermath:

1.1 The 9/11 Commission Report (2004)#

The bipartisan National Commission on Terrorist Attacks Upon the United States (the 9/11 Commission) spent 19 months investigating the attacks, interviewing 1,200 witnesses in 10 countries, and reviewing 2.5 million pages of classified and unclassified documents. Its 585-page final report:

• Confirmed al-Qaeda and Osama bin Laden planned and executed the attacks
• Documented critical intelligence sharing failures between the CIA, FBI, and NSA that prevented agencies from stopping the hijackers
• Issued 41 policy recommendations, including the creation of the Director of National Intelligence role and the TSA, to prevent future attacks
• Faced widespread criticism for limiting access to classified Saudi government-related records, leading to calls for further declassification in later years.

1.2 FEMA World Trade Center Building Performance Study (2002)#

The first official engineering analysis of the World Trade Center (WTC) collapse, published 8 months after the attacks, found that structural damage from the plane impacts and subsequent uncontrolled fires weakened steel support columns, leading to the progressive collapse of WTC 1 and 2. The report noted gaps in data that required further investigation by the National Institute of Standards and Technology (NIST).

1.3 NIST World Trade Center Investigation Reports (2005, 2008)#

NIST’s three-year, $16 million independent investigation confirmed FEMA’s initial findings, with additional detail:

• The 2005 report on WTC 1 and 2 found no evidence of controlled demolition explosives, noting that jet fuel fires burned hot enough to weaken unprotected steel beams even without direct impact damage
• The 2008 report on WTC 7 (a 47-story office building that collapsed 7 hours after the Twin Towers) found fires ignited by debris from the WTC 1 collapse caused structural failure, again finding no evidence of pre-planted explosives.

1.4 CIA Inspector General 9/11 Accountability Review (2005, partially declassified 2007)#

This internal CIA audit found that senior agency officials failed to share critical intelligence about two known al-Qaeda operatives (Khalid al-Mihdhar and Nawaf al-Hazmi, two of the 9/11 hijackers) who had entered the U.S. in 2000, with no disciplinary action taken against staff responsible for the oversight.

Major Declassified 9/11 Record Collections#

Thousands of pages of previously classified 9/11 records have been released following public pressure and congressional and executive orders:

2.1 The 28 Pages (Declassified 2016)#

Redacted from the 2002 Joint Congressional Inquiry into 9/11 for 14 years, these 28 pages documented circumstantial links between Saudi government employees and the support network for al-Mihdhar and al-Hazmi in California. The records did not find definitive evidence that senior Saudi government officials approved or funded the attacks, but they prompted further investigation into Saudi state involvement.

2.2 FBI 9/11 File Releases (2021–2023)#

Following an executive order from President Joe Biden on the 20th anniversary of the attacks, the FBI declassified more than 1,500 pages of records related to Saudi links to the hijackers. Key findings included confirmation that a Saudi embassy official in Washington D.C. had direct contact with the two hijackers’ U.S. support network, and that Saudi consular staff helped the hijackers obtain travel documents.

2.3 Senate Select Committee on Intelligence Detention and Interrogation Program Report (2014, partially declassified)#

Commonly called the “Torture Report,” this 525-page declassified summary of a 6,700-page full classified report documented that the CIA used brutal, unauthorized interrogation techniques on post-9/11 detainees, and that these techniques produced no actionable intelligence that prevented terrorist attacks.

2.4 NSA Pre-Attack Intelligence Records (Declassified 2015)#

These records confirmed the NSA intercepted communications about an impending al-Qaeda attack in the months before 9/11, but failed to share the information with the FBI or local law enforcement due to internal data sharing policies.

Common 9/11 Misconceptions Addressed by Public Records#

Public 9/11 records directly debunk many widely shared online conspiracy theories:

3.1 “The WTC buildings were brought down by controlled demolition”#

Both NIST’s 2005 and 2008 reports, as well as independent engineering reviews, found no physical evidence of explosive residue or pre-planted demolition devices at the WTC site. All debris samples tested were consistent with fire-related structural failure.

3.2 “No plane hit the Pentagon”#

Declassified FBI photos, flight recorder data, 100+ eyewitness statements, and partial security camera footage released in 2006 and 2017 confirm American Airlines Flight 77 crashed into the Pentagon. DNA samples from all 64 passengers and crew on the flight were matched to remains recovered at the site.

3.3 “The Saudi government officially planned and funded the 9/11 attacks”#

Declassified records have found circumstantial links between low-level Saudi government staff and the hijackers’ U.S. support network, but no declassified or classified record reviewed by U.S. intelligence agencies has found definitive proof that senior Saudi royal family or government officials approved or funded the attacks. Litigation between 9/11 families and the Saudi government remains ongoing as of 2024.

Ongoing 9/11 Transparency Efforts#

As of 2024, an estimated 10% of 9/11-related government records remain fully redacted or classified, including thousands of pages related to Saudi government links to the hijackers. The 9/11 Transparency Act, reintroduced in Congress in 2023, would mandate the declassification of all remaining 9/11 records with no redactions except for narrow national security carveouts. Victims’ family advocacy groups continue to push for full disclosure as a core component of accountability for the attacks.
