Explosions? Say it ain't so Firefighter Bob.
You are sooooo focused on the firefighters and the explosions they apparently heard as proof of your theories, so let's have a look ...
Conspiracy Theorists (CT) seem to have two theories: 1) explosives or 2) thermite was used to weaken the structure and ultimately cause the collapse. Jubee, in this thread you've swung between both, so let's examine both:
Thermite / Thermate:
Thermite typically requires a temperature over 3000F to ignite. Thermite is ignited using Magnesium Ribbon. The point: you don't use "explosives" to ignite thermite. If indeed thermite was used, there would have been NO EXPLOSIONS.
The reason thermite is favoured by the conspiracy types is that:
0) Thermite is NOT explosive (explosions would have provided physical evidence and the bad guys did not want evidence). Once ignited Thermite burns with great intensity and heat and no explosion ----- your own video confirms this
1) The collision and fire would not have caused the thermite to start acting early -------- However the CT fools forget the magnesium ribbon or any other activator would have ignited at below 1000F and the control wires could have been destroyed
2) The CTs point to the clean 45 degree cuts on the structure steel as evidence ------ However the CT fools don't understand that the thermite would have been placed on the pins that join the horizontal floors to the vertical support structure and NOT NOT NOT EVER the outside structural steel. Otherwise the building would not have pancaked straight down as it did, but would have fallen to one side if they even mistimed their 1000s of denotations by a fraction of a millisecond. Remember they would not have know EXACTLY where the plane was going to hit ahead of time, they therefore could not use static timing. Also even 10-20 broken control wires would have disrupted the controlled demolition and potentially caused the building to topple sideways.
3) The CTs point to the molten metal flowing out a window --- However the fools fail to realize that the thermite would have to be placed at EVERY pin around the perimeter of the structure (by the elevators AND the outside girders). Therefore we should have seen the molten flows from many locations as thermite would have burned through everything.
4) Evidence of thermite residue at the site ---- This one is the most laughable. All the chemicals and compounds that go into the creation of thermite would have been common within the building (iron oxide, aluminum oxide, aluminum, copper, etc)
Explosives:
The reason explosives is favoured by the conspiracy types is that ..... actually it's not favoured at all, for obvious reasons:
0, 1, 2, 3, 4) Explosives would have left waaaaay too much physical evidence. There is a whole expert industry (NTSB) that knows how to look for explosive evidence amongst the fire and impact destroyed rubble. Even many police are trained to look for explosive evidence.
5) Although there are directional explosives, the bad guys needed precision to assure the building would fall straight down and not over. Explosives simply aren't precise enough when they didn't know EXACTLY where the plane was going to hit and which explosives might have been disabled by broken control wires.
6) Explosives would have been donated by the collision and multi-hour fire.
7) the quantity of explosives required would have been in the 100s of toms.
8) Explosives need to be drilled into concrete columns. That takes big tools, time and leaves lots of evidence before the event.
So what did the firefighters hear? All the following are reasonable and logical possibilities (and we've already eliminated explosives and thermite doesn't explode):
1) The sound of the floor pins shearing.
2) The sound of a floor falling onto the floor below it
3) The wave energy of the collapse occurring on upper floors (traveling through the building structure more rapidly than through air) into the lobby and becoming sound energy
4) The sound of aerosol cans (paint, hairspray, keyboard cleaner, CO2 containers for fire suppression) exploding (ever throw one in a fire?)
5) The sound of UPS batteries exploding. I'll bet there were 1000s of big batteries throughout the buildings
6) The sound of structural falling or releasing tension energy. Not talking building structure, could be a office staircase falling once it's supports burned through.
Have you ever been to a building fire? The noise is immense and you can hear constant loud bangs going on. Those firefighters were under allot of stress and must have been scared as hell, do they really know what they heard?
