About 9-11 Research

9-11 Research is an ongoing effort to discover the truth about the attacks on New York City and Washington, D.C. on September 11th, 2001. To that end we provide a growing hypertext documentary of the attack and its aftermath, easily browsed archives of evidence, and a body of original analysis based on that evidence. We maintain the website as a public service.



9-11 Research critically examines the official government explanation of the attack and concludes that many of its key assertions are impossible. We do not pretend to know exactly how the attack was carried out or exactly who the perpetrators are, but there are plausible scenarios of how the attack could have been executed by insiders. (See our Frequently Asked Questions.)

If the attack was indeed a "black-op", then we can expect that the operatives will have hidden their identities behind layer upon layer of cover story. Only a genuine investigation with meaningful powers will be able to peel away the layers of deception to expose the true perpetrators. We hope to facilitate such an investigation by first exposing the falsity of the outermost cover story: the official myth of 9/11/01.

We intend for our work to honor the many victims of this horrendous attack. Many people will find it difficult and traumatic to confront the idea that the attack was the work, not of a religious extremist living in caves in Central Asia, but of people within the U.S. government. Apologists for the official story ridicule such ideas, and attempt to confuse compassion for the victims with certainty that bin Laden was the perpetrator. In fact, genuine compassion consists of learning and spreading the truth in order that future repetitions of such murderous frauds may be prevented.


The USA PATRIOT Act places restrictions on freedoms of expression guaranteed by the First Amendment to the U.S. Constitution -- restrictions that have yet to be tested in the courts. It allows individuals to be placed under electronic surveillance without their knowledge or consent, and without a court order. We have no way of knowing whether people visiting this site are being monitored, and if we did know, it would be illegal under the USA PATRIOT Act for us to share that knowledge with our visitors.

We have received several complaints of graffiti-like postings of the URLs for 9-11 Research and its companion websites in public places. We discourage and disavow such intrusive campaigning methods, which tend to be counterproductive to our mission of public education.

Who We Are

9-11 Research is a research consortium consisting of just a few individuals volunteering their time and resources to the effort. The principal contributors to the site are:

  • Jim Hoffman, Webmaster and Senior Editor
  • Gregg Roberts, Associate Editor
  • Jan Hoyer, Outreach Coordinator

Jim Hoffman created the website and wrote the vast majority of its original content. Hoffman has a background in software engineering, mechanical engineering, and scientific visualization. Hoffman also created the Web publishing system used to maintain the 9-11 Research website.

Gregg Roberts has been investigating the September 11 attack since December 2003 and has provided extensive editorial assistance to 911Research. He authored the essay Where Are the 9/11 Whistleblowers?, and is working with Hoffman to produce a book based on the site. Roberts is a technical writer and business analyst with a bachelor's degree in psychology, master's-level study in social work, and earlier education in the "hard" sciences.

Jan Hoyer is a former founding board member and graphic designer for the National 9/11 Visibilty Project, 911Truth.org and the D.C Emergency Truth Convergence. Hoyer has a degree in graphic design and experience in online multimedia.

Research History

Hoffman began development on the prototype for this website in March of 2003, shortly after discovering problems with the physics of the official explanation of the Twin Tower collapses. "Stumbled upon" is probably more accurate than "discovering," since others had already pointed out problems. In the process of researching the building collapses and other events of the September 11th attack, and the vast body of conflicting reports surrounding them, Hoffman began assembling a collection of original hypertext pages. In order to keep track of the details of this complex story, Hoffman developed a tool for creating hierarchies of web pages, with references linking to source documents, allowing quick navigation to any of its many pages with only two or three clicks. Originally developed as a research tool, the system doubled as a means of communicating our findings to others. It evolved into the comprehensive and popular website that 911Research is today.

Website History

We first posted the 9-11 Research website on the World Wide Web at the URL 911research.wtc7.net in mid-2003, within weeks of the rollout of wtc7.net. The content of the much smaller wtc7.net website was derived from the research described on the 9-11 Research website. We decided to install the front door (wtc7.net) before even half-way finishing the house (911Research).

By August of 2004 we had established a mirror of the 9-11 Research website on 911research.com. 9-11 Research currently has these mirrors:

We provide the 911research.com mirror mainly as a backup, and do not update it as frequently as the original mirror on wtc7.net. Therefore you may notice a mismatch between the version numbers on the two mirrors. Although 911research.com is easier to write than 911research.wtc7.net, we ask that you only publicize and link to 911research.wtc7.net. Linking to 911research.com instead of 911research.wtc7.net will hurt our search engine ranking.

Images and Videos

Images and video excerpts with direct bearing on the crimes of 9/11/01, such as the images documenting the collapses of the Twin Towers, are posted here with the understanding that their use is consistent with the Fair Use Doctrine. Unfortunately, we are unaware of the sources for most of these images, whom we would like to credit. Some of the photographers risked their lives, and some, like Bill Biggart, even gave their lives.

9-11 Research cached a large number of images in early 2003, when we were researching the attack, and in particular the collapses of the Twin Towers. We found all of the images on the web, and in most cases they were unattributed. Unfortunately, notes we were keeping about the sources of the images, in the form of bookmarks, were lost in a subsequent system crash. When we went public with the website in the summer of 2003 we felt ethically bound to provide our cache of images, since they are evidence for what we feel are incontrovertible proofs that the collapses of the Twin Towers and Building 7 were engineered from within -- an accusation with staggering implications given the wars and thefts of liberties predicated on the official explanation of the attack. We would appreciate any help in finding the photographers who took these extremely important photographs, if it is their wish to be credited. (We can appreciate that some photographers may wish to remain anonymous.) See our contact information.

We are grateful to all of the people who have been working on exposing the truth behind the horrific events of September 11th 2001, work we were unaware of until February, 2003. We wish to give special thanks to several individuals whose work helped to inspire the inception and development of 9-11 Research:

  • We thank the authors of the two documents which opened our eyes to the bankruptcy of the official explanations of the collapses of the Twin Towers:
  • We are grateful to Paul Thompson, whose detailed and well-sourced timelines have been an invaluable resource in the development of this website.
  • We thank Don Paul, who organized many events that helped to popularize the message of 9-11 Research in the form of persuasive slide presentations starting September 11, 2003, and continues to expose the the relevance of the physical evidence of the 9/11/01 attack to the unsustainable and unjust nature of the larger economic system.
  • We thank physics professor Steven E. Jones, whistleblower Kevin Ryan, and architect Richard Gage, each having combined their impressive credentials, meticulous research, and persuasive and courageous outreach to advance the cause of 9/11 Truth in profound ways.
