Some Misunderstandings Related to WTC Collapse Analysis

[Jeffrey Orling]

The columns are not involved in either the initiation or first several stories of the drop of both buildings and that is impossible in a natural collapse.

So what was blown? Sounds like not all that much. Thermite? Where was it used?

With regards to some witness testimony about explosions at ground level or even below ground level, what is your read there? It gets dismissed as jet fuel come down the elevator shafts.

I suspect that there were explosions of electrical switch gear in the basement level. This equipment was shorted when the plane severed the 13.8kv electrical risers going up to floor 108 where there 2 of the 8 massive sub stations which distributed power through out the tower.

High voltage electrical gear gets very hot and needs to be cooled and insulated. The massive transformer of the Con Ed sub station below 7 had massive radiators with oil circulating through them for cooling. The cooling oil used in electical transformer when overheated turns to gas and of course explodes since its volume is so much larger than the liquid oil. Some types of coolant is flammable as well when it is in gas form and so that can flash over an explode as well or cause fires to spread.

The explosion in the basement of wtc 1 were famously reported by William Rodriguez... I think this is what you refer to. I have spoken with William about this memory and he told me the following:

The sound of the explosion preceded the sound and vibration etc of the plane striking by 1 second or so. Clearly he is not a stop watch so the term 1 second is an approximation for a very brief interval of time. Explosion then plane strike in that order... very close in time.

He has never heard an power transformer explosion (i've heard them many times and they are rather common and do sound very loud and like a bomb explosion to me)

He did not say the explosions were bombs... but that they were explosions. He had no idea what had exploded.

He said he knew there was electrical switch gear in close proximity to the elevator where the burnt worker emerged for the freight car.

"THE PHENOMENON
During a transformer short-circuit, the electrical arc vaporizes oil and creates a Dynamic Pressure Peak which travels at the speed of 1,200 meters per second (4,000 feet per second). This phenomenon occurs within a few milliseconds. Because of reflections in the tank the pressure peak will generate pressure waves. The integration of all of the waves pressure peaks creates static pressure. Then, the pressure becomes equal throughout the entire transformer tank within 50 to 100 milliseconds after the electrical arc, and causes the transformer tank to rupture."

Sound travels at 1100 feet per second and so anyone on the ground seeing the plane hit would hear it at LEAST 1 second after the impact. If they were 5 clocks away they would hear it 2 seconds after the impact. Therefore it is virtually IMPOSSIBLE for witnesses to correlate sounds precisely and sights unless they are very close to the event.

Ergo boom boom boom... may be the sounds not of explosions but of the parts of the structure dropping. Collapsing massively heavy objects make very loud sounds. Witness a 20 yard container dropped onto the ground.

The WTC contained hundreds of electrical transformers. Of course not all of them exploded. But clearly some of them did... because the WTC was fully energized on 9/11 including use of back up power of diesel fueled systems.

Gas explosions clearly are destructive like bombs... which are... gas explosions... all explosions are rapidly expanding gas!

All bombs explode
not all explosions are bombs
