Twenty-five years after the September 11 attacks, Matt Campbell, whose brother Geoff was killed in the World Trade Center, contends that the event was not solely a terrorist atrocity but also a significant cover-up.

Campbell believes that incendiary devices, rather than the hijacked airplanes, were responsible for the collapse of the Twin Towers and World Trade Center 7. He suspects that U.S. government and intelligence agencies may have played a role in this alleged deception. Campbell is scheduled to speak at the conference 'Turning the Tide: 9/11 25 years later' in New York, where he will join other speakers, including first responders, to discuss their theories. He also plans to attend a Supreme Court hearing in London related to 9/11 justice.

Campbell's quest for answers began after reading articles describing the war in Afghanistan as a "farce." He subsequently read over 160 books on the disaster, initially focusing on intelligence failures. He stated, "As I started to look, I got frustrated that nobody was being held accountable."

His brother, Geoff Campbell, a British national working for Reuters, was killed on the 106th floor of the North Tower, trapped above the impact zone. Matt Campbell remembers his brother as "such a funny, nice guy" who was exceptionally talented.

Official Narrative and Alternative Theories

The official account from the National Institute of Standards and Technology (NIST), a branch of the Commerce Department, concluded that the impact of the planes caused the Twin Towers to collapse. NIST's investigation stated that debris from these collapses ignited fires in WTC 7, leading to its destruction later that day. NIST declined to comment for this article, directing inquiries to their published reports.

Campbell challenges NIST's findings, particularly regarding WTC 7. He finds the explanation of normal office fires causing its collapse improbable, especially given the building's freefall acceleration for 2.5 seconds. He asserts that eyewitness accounts and expert testimony suggest the use of explosives or incendiaries. Richard Gage, an architect and proponent of the theory that explosives felled the Twin Towers, supports this view, stating that jet fuel cannot melt steel, only incendiaries can.

NIST's report counters this, explaining that fires caused WTC 7's steel beams to expand, leading to the failure of a key structural column and a subsequent progressive collapse. The report found no evidence of blast events or incendiary devices in any of the WTC buildings.

Accountability and Legal Proceedings

Campbell expressed frustration with the lack of accountability, noting that Khalid Sheikh Mohammed, the alleged mastermind of the attacks, has yet to stand trial after two decades in Guantanamo Bay. A judge ruled that confessions obtained under torture cannot be used in his trial. Additionally, a lawsuit filed by 9/11 families against Saudi Arabia, alleging complicity in the hijackers' actions, is moving forward but Campbell anticipates a settlement.

He also criticized the 9/11 Commission's final report for its minimal discussion of how the Twin Towers collapsed. An inquest into Geoff Campbell's death and those of 10 other British victims in 2013 lasted only 90 minutes. Matt Campbell is seeking to have this reopened, with a hearing scheduled for October at the UK's Supreme Court to determine the Attorney General's power to block a renewed inquest without court oversight.

Campbell maintains that he does not subscribe to the idea of "closure," emphasizing the need for evidence regarding his brother's death to be presented in court. He stated, "This (9/11) will be debated forever. But I want a trial, I want evidence to be tested, that's what you expect after a murder - let alone a mass murder."

The 9/11 attacks, which resulted in the largest single loss of civilian life in U.S. history, were among the first events whose narratives were significantly shaped by the internet, fueling numerous fringe theories and unsubstantiated claims.
