Preface: Now that Bin Laden has been confirmed to be dead, it has been established that Saddam Hussein was not behind 9/11 (one of the main reasons for the Iraq war), and Iran has been accused of having a hand in 9/11 – potentially forming the basis for a war against Iran – it is time to revisit some important, unanswered questions.
This essay does not argue that bombs brought down the Twin Towers or World Trade Building 7, even though many top structural engineers believe that is what happened, and people could easily have planted bombs in the trade centers without anyone noticing and without the conspiracy being discovered.
It simply addresses the frequent argument that fires caused the metal to sag, which brought down the 3 buildings, and that the case is closed.
The Fires at the World Trade Centers Were NOT Very Hot
The government agency in charge of the investigation of why three buildings collapsed on 9/11 – the National Institute of Standards and Technology (NIST) – says that paint tests indicated low steel temperatures — 480 Fahrenheit — “despite pre-collapse exposure to fire”. NIST also said that microstructure tests showed no steel reached critical (half-strength) values of 600 Celsius (1112 degrees Fahrenheit) for any significant time.
Numerous top fire protection engineers have said that the fires in the World Trade Centers were not that hot. For example:
- A mechanical engineer with 20 years experience as a Fire Protection Engineer for the U.S. Departments of Energy, Defense, and Veterans Affairs, who is a contributing Subject Matter Expert to the U.S. Department of Energy Fire Protection Engineering Functional Area Qualification Standard for Nuclear Facilities, a board member of the Northern California – Nevada Chapter of the Society of Fire Protection Engineers, currently serving as Fire Protection Engineer for the city of San Jose, California, the 10th largest city in the United States (Edward S. Munyak) says that the fires weren’t big enough to bring down Building 7:
