Why the towers fell: Two theories

(William Rice, P.E., is a registered professional civil engineer who worked on structural steel (and concrete) buildings in Boston, New York, and Philadelphia. He was also a professor at Vermont Technical College where he taught engineering materials, structures lab, and other building related courses.)

Having worked on structural steel buildings as a civil engineer in the era when the Twin Towers were designed and constructed, I found some disturbing discrepancies and omissions concerning their collapse on 9/11.

I was particularly interested in the two PBS documentaries that explained the prevailing theories as determined by two government agencies, FEMA and NIST (National Institute of Science and Technology). The first (2002) PBS documentary, Why the Towers Fell, discussed how the floor truss connectors failed and caused a “progressive pancake collapse.”

The subsequent 2006 repackaged documentary Building on Ground Zero explained that the connectors held, but that the columns failed, which is also unlikely. Without mentioning the word “concrete,” the latter documentary compared the three-second collapse of the concrete Oklahoma City Murrah Federal Building with that of the Twin Towers that were of structural steel. The collapse of a concrete-framed building cannot be compared with that of a structural steel-framed building.

Since neither documentary addressed many of the pertinent facts, I took the time to review available material, combine it with scientific and historic facts, and submit the following two theories for consideration.

The prevailing theory

The prevailing theory for the collapse of the 110-story, award-winning Twin Towers is that when jetliners flew into the 95th and 80th floors of the North and South Towers respectively, they severed several of each building’s columns and weakened other columns with the burning of jet fuel/kerosene (and office combustibles).

However, unlike concrete buildings, structural steel buildings redistribute the stress when several columns are removed and the undamaged structural framework acts as a truss network to bridge over the missing columns.

After the 1993 car bomb explosion destroyed columns in the North Tower, John Skilling, the head structural engineer for the Twin Towers, was asked about an airplane strike. He explained that the Twin Towers were originally designed to withstand the impact of a Boeing 707 (similar in size to the Boeing 767). He went on to say that there would be a horrendous fire from the jet fuel, but “the building structure would still be there.”

The 10,000 gallons of jet fuel (half capacity) in each jetliner did cause horrendous fires over several floors, but it would not cause the steel members to melt or even lose sufficient strength to cause a collapse. This is because the short-duration jet fuel fires and office combustible fires cannot create (or transmit to the steel) temperatures hot enough. If a structural steel building could collapse because of fire, it would do so slowly as the various steel members gradually relinquished their structural strength. However, in the 100-year history of structural-steel framed buildings, there is no evidence of any structural steel framed building having collapsed because of fire.

Let’s assume the unlikelihood that these fires could weaken all of the columns to the same degree of heat intensity and thus remove their structural strength equally over the entire floor, or floors, in order to cause the top 30-floor building segment (South Tower WTC #2) to drop vertically and evenly onto the supporting 79th floor. The 30 floors from above would then combine with the 79th floor and fall onto the next level down (78th floor) crushing its columns evenly and so on down into the seven levels below the street level.

The interesting fact is that each of these 110-story Twin Towers fell upon itself in about ten seconds at nearly free-fall speed. This violates Newton’s Law of Conservation of Momentum that would require that as the stationary inertia of each floor is overcome by being hit, the mass (weight) increases and the free-fall speed decreases.

Even if Newton’s Law is ignored, the prevailing theory would have us believe that each of the Twin Towers inexplicably collapsed upon itself crushing all 287 massive columns on each floor while maintaining a free-fall speed as if the 100,000, or more, tons of supporting structural-steel framework underneath didn’t exist.

The politically unthinkable theory

Controlled demolition is so politically unthinkable that the media not only demeans the messenger but also ridicules and “debunks” the message rather than provide investigative reporting. Curiously, it took 441 days for the president’s 9/11 Commission to start an “investigation” into a tragedy where more than 2,500 WTC lives were taken. The Commission’s investigation also didn’t include the possibility of controlled-demolition, nor did it include an investigation into the “unusual and unprecedented” manner in which WTC Building #7 collapsed.

The media has basically kept the collapse of WTC Building #7 hidden from public view. However, instead of the Twin Towers, let’s consider this building now. Building #7 was a 47-story structural steel World Trade Center Building that also collapsed onto itself at free-fall speed on 9/11. This structural steel building was not hit by a jetliner, and collapsed seven hours after the Twin Towers collapsed and five hours after the firemen had been ordered to vacate the building and a collapse safety zone had been cordoned off. Both of the landmark buildings on either side received relatively little structural damage and both continue in use today.

Contrary to the sudden collapse of the Twin Towers and Building #7, the four other smaller World Trade Center buildings #3, #4, #5, and #6, which were severely damaged and engulfed in flames on 9/11, still remained standing. There were no reports of multiple explosions. The buildings had no pools of molten metal (a byproduct of explosives) at the base of their elevator shafts. They created no huge caustic concrete/cement and asbestos dust clouds (only explosives will pulverize concrete into a fine dust cloud), and they propelled no heavy steel beams horizontally for three hundred feet or more.

The collapse of WTC building #7, which housed the offices of the CIA, the Secret Service, and the Department of Defense, among others, was omitted from the government’s 9/11 Commission Report, and its collapse has yet to be investigated.
Perhaps it is time for these and other unanswered questions surrounding 9/11 to be thoroughly investigated. Let’s start by contacting our congressional delegation.



Pearl Harbor; We knew about this one too!

Quick stats on Pearl Harbor:
– Pearl Harbor attacked Sunday, December 7, 1941
– Two waves of attacks: 7:49 A.M. and 9:00 A.M.
– First wave included 183 Japanese dive- and torpedo-bombers with zero escorts
– Second wave included an additional 168 Japanese planes.
– 18 operational warships sunk, including four battleships, sunk or damaged
– 188 aircraft destroyed
– 2,403 Americans killed (68 of them civilians)
– 1,178 Americans wounded

Many Americans are unaware that evidence regarding Pearl Harbor points to our government being fully aware of the attacks that were to take place on December 7, 1941. Much like the assassination of JFK and 9/11, “conspiracy theorists” (although in this case, the people uncovering the truth were less ‘theorists’ and more ‘realists’) have accumulated a wealth of evidence to support such a claim.

During that time, President Franklin D. Roosevelt was in a bind. An overwhelming 80% of Americans were opposed to entering WWII as an active participant. After Pearl Harbor, things quickly changed and Roosevelt gained wide support from Congress to declare war on Japan. Much like the aftermath of 9/11, however, questions around the attack immediately surfaced.

Why was America attacked? Was it avoidable? Were the Japanese going to attack again? Why didn’t our readily available Army and Navy commanders (Admiral Husband E. Kimmel and General Walter Short) fumble in their job to protect one of America’s most important naval bases? …and of course, WHO WAS RESPONSIBLE?

Roosevelt was all too aware of the questions surrounding the attack and quickly summoned up a special commission to investigate. Big surprise! (Side note: The trend of creating “special commissions” didn’t begin here, but has come to be -just what you do- after shit hits the fan or to distract the public from the real issue – see Pearl Harbor, JFK, Watergate, Clinton-Lewinsky, 9/11, steroids and baseball…hell even the Bowl Championship Series gets a special commission in Washington! The sad thing is these commissions wouldn’t happen if the average American was smarter than our President and recognized them as what they are – smoke and mirrors. Again, I digress! Back to the topic.) Anyway the chair of this commission was Associate Supreme Court Justice Owen J. Roberts. The interesting thing about this man is that he was the leading advocate of the Committee to Aid America by Aiding the Allies. It’s a no-brainer what happened next. The commission absolved any high ranking political and military members, except for two – Admiral Kimmel and General Short! Suffice to say, they were blamed for being unprepared, removed from their positions and demoted. It’s amazing the MacGyverish things you can do with smoke and mirrors, eh?

Back to the topic at hand. It’s widely known now that the U.S. had some vital information regarding an imminent attack on Pearl Harbor. However, this information was not passed on to the Naval and Army commanders. The blunder of Pearl Harbor was originally blamed on political mismanagement of critical intelligence information.

This of course doesn’t explain why we did nothing to prevent Pearl Harbor, even in the face of intercepted Japanese messages (which were received in Washington as early as Dec 4th indicating failing relations and irreversible action against U.S. interests). The message in question is referred to the EAST WIND RAIN message, which Roosevelt and his cronies denied ever receiving. Chief Warrant Officer Ralph T. Briggs who was working at the Cheltenham, Maryland intercept station in late 1941 however, testified that he received the message, and Navy memoirs indicated that the message had even been received prior to him getting it. This testimony was backed up by a man named Captain Laurence Safford.

Whether or not our govt. knew exactly where Japan was going to attack remains unclear. But what is clear is that: there was no real urgency to alert the commanders at Pearl Harbor, our government did in fact know of an impending attack, our govt. knew who would attack us, and they very well knew where we’d be attacked (EAST! WIND! RAIN!). So Roosevelt and his buddies sat and waited for the attack and quickly used it as an excuse to go to war with Japan.

God, does history repeat itself or what?!

I’ll write a little more about this later, but alas, it’s time for me to leave work. 🙂 For more info, GOOGLE it!
