PAPA Heading to:
National Fire Protection Association (NFPA) Convention | Coming up June 16-18, 2025
Las Vegas, NV

NFPA-2025-PayPal-1200x400 (1).jpg

PAPA will host yet another WTC evidence booth when the NFPA heads back to Las Vegas, NV for their 2025 Convention! We will once again bring to the attention of thousands of firefighters & fire protection engineers the facts and the critical need for investigating World Trade Center Building 7.







The PAPA Team educates NFPA convention goers every year about the 7-second collapse of the

Solomon Brothers Building -- and it's implications for the fire protection industry.


Our honored guests in 2024 included year will be retired Seattle Fire Department Captain Raul Angulo - the author of the book about how to fight fires in buildings - Engine Company Fireground Operations, 4th edition, written in partnership with the NFPA and Jones & Bartlett Learning.






We will also be speaking in the Theater #2 Classroom on the Expo floor: "Did the Salomon Brothers High-rise Building (WTC 7) really collapse from fire?  New University Forensic Study Concludes Otherwise" We hope you will join us there!












And of course we will be bringing  back Ret. Seattle Firefighter Erik Lawyer, founder of Protecting all Protectors Alliance, as well as Architect Richard Gage, AIA, founder and former CEO of Architects & Engineers for 9/11 Truth.



We asked Captain Angulo why the high-rise fireground operations strategy had not changed in the wake of the Salomon Brothers (WTC 7) building collapse. This began a conversation about the NIST investigation, and the complete absence of strategy changes after the first ever global collapse of a Type 1 high-rise building that was attributed to fire.



We made more than 600 professional connections at the Boston and Las Vegas Conventions and hope to double that amount in Orlando with our expanded PAPA crew. It is critically important to educate the industry about the huge discrepancy between the NIST claims of WTC 7's "collapse by fire" versus the reality of current high-rise firefighting strategies which involves setting up forward operating centers 2 floors below the fire and directing occupants above the fire to remain in place until the firefighters complete their firefighting operations.

We are currently in conversation with VIP's affiliated with the NFPA who have demonstrated that they do care about Building 7 and the future of fire investigations. Help us to reach 300 more in Orlando! 

We need your support with our non-profit mission. If we all chip in $20 or $100 then we can bring the experts to the NFPA Conference!



This year we have been invited by the NFPA to present the results of the independent study, A Structural Re-evaluation of the Collapse of World Trade Center 7 by the University of Alaska's former Chair of the Structural Engineering Department, Prof. Leroy Hulsey - one of the top forensic structural engineers in the country. This presentation occurs in the Expo Theater #2 on Wednesday June 19 at 11:00am. The study concludes that the evidence clearly indicates that WTC 7 was not brought down by fire, as NIST claims - but by the failure of all of the columns in the building.

     I want to thank you for visiting the Protecting All Protectors Alliance (PAPA) booth at the recent NFPA conference. I also want to congratulate you for taking the first step in asking important questions about how this unprecedented collapse happened to the Solomon Brother’s building (WTC 7).


     In my research on highrise building fires for my book, Engine Company Fireground Operations 4 th Edition, published by Jones and Bartlett Learning, in conjunction with NFPA, I was surprised to learn that not a single Type I construction highrise building in the USA, or around the world for that matter, has collapsed due to fire – despite the fact that many of these fires were quite spectacular. Because significant highrise fires are rare, those that have already occurred still remain our primary case studies. Yet after 20 years, the complete global collapse at freefall acceleration of WTC 7 continues to be unknown, overlooked, or even ignored by many fire service professionals. This fire, compared to the others, was anything but spectacular. On any other date, this building collapse would have received national attention, and would become an exclusive case study that would be studied extensively for years to come.


     When you consider the fire load inside WTC 7, primarily office furnishings, it is difficult to believe that such a fire load could release the amount of thermal energy required to weaken a single structural column that would completely collapse such a building. Type I construction, the strongest of the five classes, is designed to withstand the common office fire load. In other words, the fuel should be consumed before structural components are compromised. Yet, per their own report, that is what the National Institute of Standards and Technology (NIST) wants us to believe.


     Two important documents now exist that challenge the NIST report conclusion and the narrative on WTC 7. The 2020 study out of the University of Alaska by Professor J. Leroy Hulsey – A Structural Reevaluation of the Collapse of World Trade Center 7, and the new 2021 NFPA Standard 1700, Guide for Structural Fire Fighting. The Hulsey conclusion does not attribute the collapse of WTC 7 to a single column failure due to fire involvement, and NFPA 1700, Chapter 12 on Highrise Fires implies that all operations, including sheltering or protecting occupants in place, occur during interior operations. There is no mention of “fire-induced progressive collapse” - as NIST claims is a new phenomenon, nor any mention or warning of the potential of structural collapse when fighting fires in highrise buildings. This is why this topic finally needs to be addressed.


     As you can see, there are major discrepancies in the information that firefighters rely on to be truthful and accurate. Both firefighter and civilian lives depend on the veracity of information that is published by such organizations. As an author of a textbook that is providing guidance for the dangerous assignments of interior offensive attack and interior search and rescue of trapped occupants, I need my readers to trust what I am saying is true. It is a matter of personal integrity and trust. Therefore, I must rely on the information I’m getting from architects, building and fire protection engineers, and professional organizations like Underwriters Laboratories (UL), NFPA, USFA, NFA, NIOSH, and NIST are also telling me the truth. We must rely on physical science, not political science, lest we violate the public trust and endanger the lives of civilians and firefighters.


     I encourage you to watch Calling Out Bravo 7, 2020 edition on the PAPA website. Many of your questions, as were mine, were answered after watching this excellent documentary.


My best to all of you as we go forward to establish the truth.
