The heat at Ground Zero was not only extreme, it was also persistent, as proven not only by witness statements and a photograph by LiRo Group/Engineering of orange-red glowing steel as late äs October 21, but also by thermal images taken by NASA and EarthData satellites. The EarthData thermal images also show that the "hot spots" remained at the same locations.

The extremely high temperatures contradict the official story.

High Temperatures, Persistent Heat & 'Molten Steel' at WTC Site Challenge Official Story
By Richard Gage, AIA & Andrea Dreger & Gregg Roberts
from 911 Investigator 1.1
An excavating machine lifts debris dripping with molten metal

Extremely high temperatures were evident before and during the destruction of the World Trade Center Twin Towers and at Ground Zero. Seven minutes before the destruction of the South Tower, a flow of molten metal appeared, accompanied by several smaller flows, as documented by the National Institute of Standards and Technology (NIST). The material's glowing color showed that its temperature was close to "white hot" at the very beginning of the flow and "yellow-orange" further down. Iron-rich spheres in the WTC dust are additional proof of temperatures above the melting point of iron. Pyroclastic-like, rapidly expanding dust clouds after the destruction of the Towers can also be explained only by the expansion of hot gases.

The high-temperature phenomena at Ground Zero are documented by various sources:

Bechtel engineers, responsible for safety at Ground Zero, wrote in the Journal of the American Society of Safety Engineers. "The debris pile at Ground Zero was always tremendously hot. Thermal measurements taken by helicopter each day showed Underground temperatures ranging from 400°F to more than 2,800°F."

The fact that high-temperature phenomena were an important issue at Ground Zero is underscored by the large number of thermal images acquired: images by SPOT, MTI, AVIRIS/NASA, "Twin Otter"/U.S. Army, and at least 25 images by EarthData, taken between Sept. 16 and Oct. 25. In addition, temperature measurements by helicopter were taken each day, and the firefighters used onsite sensors too.

Many witnesses, including rescue personnel and firefighters working on the piles, described the phenomenon of "molten steel". Terms used in witness Statements are, for example, "molten steel," beams "dripping from molten steel," "molten steel ... like you're in a foundry. Like lava, from a volcano." A photograph taken on September 27 by a Ground Zero worker shows an excavating machine lifting debris from the WTC wreckage dripping yellow/orange molten metal.

Sept 16, 2001 thermal images reveal 1,400°F temperatures at the surface of the WTC 1, 2 & 7 debris piles — yet there were no fires at the surface after the collapses. These surface temperatures indicate much higher temperatures below the surface

WTC clean-up workers and 9/11 artifacts architect Bart Voorsanger, in the PBS video "Relics from the Rubble," described what must have been several tons of "fused element(s) of steel ... molten steel and concrete and all of these things ... all fused by the heat," weighing several tons each. These foreign objects came to be known as "meteorites."

The heat at Ground Zero was not only extreme, it was also persistent, as proven not only by witness statements and a photograph by LiRo Group/Engineering of orange-red glowing steel as late äs October 21, but also by thermal images taken by NASA and EarthData satellites.
