I am Richard Humenn. I am a retired professional electrical engineer. I went through Brooklyn Polytechnic Institute and received the Bachelor of Electrical Engineering degree in 1954. I worked for Joseph Loring for 41 years and was principal chief electrical engineer for the World Trade Center complex.
I was trained in Fort Belvoir School to use demolition practises on bridges and other structures as well as roadways.
On September 11th I was watching live TV from my kitchen and saw the whole thing. I saw the repetition of the actual incidents and thereafter I was in a state of shock because it was unbelievable to me, knowing the strength of the structures, that a single incident of a plane impacting and fuel burning would be the reason for the towers to collapse. I just did not believe it. It was like a dream. A nightmare.
After watching the DVD from the Architects and Engineers for 9/11 Truth I was compelled to look into the matter in much more detail in my mind and in my memory and even though I'm an electrical engineer, I took basic courses in structure while going to college as well as physics and industrial chemistry, so I'm not unknowledgeable about these trades.
I was impressed by the level of detail and information that was presented in the DVD. I strongly feel that an international commission should be formed to look at this matter in an unbiased manner and come to a conclusion that could be presented to the entire engineering community.
Well, I would be more comfortable if I said something first...that the pancake theory that was initially proposed did not work. It was not feasible because if the floors pancaked, the columns would still be standing. That would have meant all the connections to the girders on both sides, interior and exterior columns, would have been disconnected for the pancake theory to work. So, it's an invalid theory.
The only way that I can see that the towers could have collapsed is that the interior columns were compromised, and by being compromised the center of the towers would become virtual black holes sucking everything in to the center of the towers.
I was very familiar with the twin towers' elevator systems because we took over conceptual maintenance and improvements of the elevator systems after the project was completed. I actually rode up and down elevator shafts on the top of a car going 1200 feet a minute, you can imagine the experience! I'm very familiar with the interior structure that surrounded the elevator shafts and the accessibility which the elevator companies had 24/7, and could visualize that the columns could have been set up with explosive devices during the off-hour operations of the building by elevator company personnel.
The elevator companies generally did work at night, when the building was closed down. I believe elevator personnel could have been involved because they had 24/7 access to the shafts which is the normal time in the evening and early morning hours when they perform their maintenance. And, of course, their access to the elevator shafts gave them total access to the surrounding core columns... the interior of the core columns.
I even expounded a theory that this collapse may have started at the top, where the floor gave way under the weight of the substation transformers, which weighed like over 30,000 pounds apiece, and there were four on one side, four on the other, and once they had gone through they would have cascaded down and down. But, again, if that happened, the interior columns and the exterior columns would still be standing. They were independent structures, as I explained before, that the interior column Faraday cage, belted around each floor with deep girders, stood alone from the exterior columns, also belted with deep girders, and the purpose of the floor trusses was simply to support a concrete floor. Now, the connections made, I believe the connections made, did not fail between the girders and the trusses, because, as I mentioned before, the black hole effect, everything was sucked inward and the pin connections that held the exterior columns to the trusses were pulled inwards towards the middle, and I visualize only the interior columns being compromised by falling within each other like a telescope. And that could only have been done by explosive charges.
There were four on each side of the towers. There were two substations on the 108th floor, the 75th floor and the 41st floor and the 7th floor. At those eight locations there were four transformers in each substation that weighed over 30,000 pounds I believe (but in that area). And they were certainly very...the heaviest part of the mechanical floor were those transformers and anything else that was up there was inconsequential as far as weight goes.
The transformers would not explode on their own – they were air cooled, dry tight transformers. For them to be totally pulverized at the bottom...it was a shame that after the collapse that a forensic engineering unit didn't go into the debris and try to find, at that time, why the towers had collapsed. I'm sure there was other evidence that could have given a better indication at the time that there was something else wrong.
Well, they didn't take them out! I recall seeing a public television show, PBS show, where the firemen were in the lobby of, I forget whether it was tower 1 or tower 2, but the plane had already hit, and what I noticed was the lights were still on in the lobby. Now, that led me to believe that the plane never got to the core columns because the feeds for all these transformers, feeding all the light and power in the towers, were adjacent to the core columns, 15kV feeders that fed these transformers, and they were attached...they were wire-armour cabled in conduit attached to the side of two of the core columns going up each tower. And if the lights were still on, the substations were still operational...right after the planes impacted.
There were 32 30,000 pound plus, maybe, transformers...powered transformers, in the substations on the mechanical floors in each tower. And yet after the collapse there was, from what was reported, there was no evidence of them being found at the bottom of the towers. I wonder why.
When I was watching, reviewing again and again when they repeated the collapse of the towers, I noticed in tower 1, unless my eyes were deceiving me, before the tower started collapsing from the top, the antenna started to fall. And the antenna, of course, was over the middle of the elevator shafts and I could see that antenna just falling down through the shafts directly to the bottom before the entire tower did collapse. And I question too, why the tower started collapsing from the top down, why not at the point of impact? That didn't make sense to me at all.
The plane, the fuel and the fire that emanated was not sufficient to bring those towers down alone.
