Debris removal specialist: Richard riggs saw melted beams, molten steel

If anyone thinks that there could be pools of molten steel or beams 'dripping' then they seriously underestimate what it takes to melt steel and keep it in a molten state.

They should take a trip to a local foundry ands see what i takes to melt just few pounds of iron. Better yet go to a steel mill and see what is needed to just heat steel beams up to a point where they can be rolled into shape.

Indeed it does. However, that does not rule out the possibility of unignited thermite igniting later in the pile. In fact once steel is molten, by whatever means, if it was insulated correctly it could stay molten.



They were iron spheres. Denying them won't make them go away. The RJ Lee report documented them, not just Steven Jones.

The thermite poster boy Niels Harrit admits it would take tons of conventional explosives alongside the tons of thermite,so how was all that planted in WTC1,2 and possibly 7?
Thermite is reportedly difficult to ignite ,what do you think could have ignited it "later" that faled to ignite it orignally?

The amount of energy it would take to keep steel "molten" for weeks, I mean, can they be serious?

Part of the difficulty in talking with truthers is their insistence on taking words literally and/or making up new definitions. If someone said they saw splatters of melted metal (as in previously liquid but now cooled and solid) weeks after 9/11 - why would anyone be surprised?? Aluminum and other metals melt and solidify again all the time in house or electrical fires.

In truther speak, splatters of previously melted metal becomes "huge pools of red hot molten steel weeks later." :boggled:

It would indicate temperatures higher than office content fires which would provide some corroboration to thermite theories. For the thermite theory to be true you would expect molten steel or iron. How do you explain the Iron spheres in the dust?

There is no temperature limit for "office content fires". Most combustible materials consist, in some form, of carbon and hydrogen. The temperature they can provide depends on the supply of oxygen and the loss of heat.

In an open air fire, where heat removal and fresh air are both provided by convection, you can make reasonable estimates of what temperature levels to expect, but in more closed systems, like inside buildings and inside wreckage heaps, all bets are essentially off.

Also, given the right conditions, a number of metals can burn (that is essentially what happens in thermite, btw), and they will generally burn at very high temperatures.

However, to sum up, it is quite possible that conditions to melt steel could have existed, both in the burning buildings, and in the wreckage heaps after the collapses. Especially the latter.

It is also important to note that the presence of molten steel in any substantial amount is not well supported. The expert witness cited seems to provide mostly second-hand testimony, and there are no documented reports of it.

But the truthers showed us a photo of glowing red material being pulled from the wreckage, they're so smart they can tell exactly what is in from a picture! :rolleyes:
 
Ahh, thank you (I assume, of course, that the quote is complete and bona fide):

RJ lee report:

“Various metals (most notably iron and lead) were melted during the WTC Event,
producing spherical metallic particles. Exposure of phases to high heat results in the formation
of spherical particles due to surface tension…”
“In addition to the vesicular carbon components, the high heat exposure of the WTC
Dust has also created other morphologically specific varieties of particulate matter including
spherical metallic, vesicular siliceous and spherical fly ash components. These types of particles
are classic examples of high temperature or combustion by-products and are generally absent in typical office dust…”
“Particles of materials that had been modified by exposure to high temperature, such
as spherical particles of iron and silicates, are common in WTC Dust because of the fire that
accompanied the WTC Event, but are not common in “normal” interior office dust…”
The presence of lead oxide on the surface of mineral wool
indicates the existence of extremely high temperatures during the collapse which caused metallic
lead to volatilize, oxidize, and finally condense on the surface of the mineral wool [1].

My highlight.

It says normal interior office dust. Repeat interior office dust.

Not "dust from office fires". Probably because there is a limited database on what is in dust from office fires. After all, why would one normally analyse that?

Whereas the content of normal office dust has been comprehensively explored, for health and safety reasons.

And, of course, the text has a sensible bid on how the metal deposits were formed: All those building parts snapping and crumbling probably made quite some fireworks, had it been visible through the dust, and in daylight.

Actually a Debris Removal Expert is a type of construction contractor. They are actually quite skilled at what they do. You see there are often these horrible situations with collapsed structures where trying to clear the site is going to be very dangerous. You have multiple walls leaning on each other and other such things. The debris removal crews will come in and formulate plans to build temporary supports, erect scaffolding and build access ramps to bring in heavy equipment. They often have to come up with very complicated support rigging to keep things stable while they are disassembled into pieces small enough to be trucked offsite.

It's a very dangerous job that takes a lot of skill and experience.

I'm not sure that allows them the ability to differentiate different molten metals though.
