9/11 World Trade Center Fly Ash Looks like this

September 11th Fly ash

Fly ash consists primarily of oxides SiO2, Al203 Fe2O3 CaO (Lime) MgO SO3

“The unique spherical shape and particle size distribution of fly ash make it a good mineral filler”

the WTC “fly ash” is not spherical shape so it is NOT “fly ash” to begin with, so this is an example of lying.

Lava was created on 9/11 and the only know material available was steel and concrete floors.

Underground fires burned at temperatures up to 2,000 degrees. As the huge cranes pulled steel beams from the pile, safety experts worried about the effects of the extreme heat on the crane rigging and the hazards of contact with the hot steel. OSHA

When Leslie E. Robertson was talking about " a little river of steel." was that river still a red hot and still flowing river or was it a river of steel that was frozen in time and was a flowing river of steel at one point in time?

A few months after 9/11, Mr. Robertson gave a talk at Stanford. You can see part of it in the below video at 3:57. He says “We went down to the B-1 [basement] level and one of the firefighters said ‘I think you’d be interested in this,’ and they pulled up a big block of concrete and there was like a little river of steel, flowing.”

“Flowing” sounds like red hot and melted to me.

A New York Times science writer, Dr. James Glanz claimed he saw a stalagmite of formerly-molten steel in the WTC debris pile. The article was Nov. 15, 2001 “A NATION CHALLENGED: THE SITE; Below Rubble, a Tour of a Still-Burning Hell”

He wrote:

“A three-foot stalagmite of steel, which looks for all the world like a drip candle, sits next to one of the immense steel columns that held up the north face of the tower.”
