Temperatures at Ground Zero were 600 to 1,500 °F for 6 months after 9/11. Ed Ward has pointed out this most likely due to retained heat from an underground nuclear explosion rather than a fission process advocated by the Anonymous Physicist. The MASSIVE explosion heard 17 seconds before the North Tower came down is a good candidate for the explosion that caused the elevated ground temperatures:
As an example of retained heat from a nuclear explosion, Ed references The Project GNOME detonation on December 10, 1961 near Carlsbad, New Mexico:
Measurements of an earlier underground detonation had indicated that roughly 1/3 of the energy was deposited in the melted rock at temperatures above 2,000 degrees Fahrenheit. This information encouraged hopes that a nuclear detonation in a dry medium might cause heat to be stored long enough to permit efficient recovery. GNOME was developed with the idea that a nuclear detonation in a salt deposit would create a large volume of hot melted salt from which heat might be extracted. The possibilities to be investigated for the production of power were the tapping of the steam created by detonation itself and the generation of high-density, high-pressure steam by the circulation of some heat-absorbing fluid, like water, over the heated salt. This generated steam would be used to drive a steam or hot gas turbine coupled with an electric generator.
When workers reentered that cavity on May 17, 1962, they found temperatures around 140 degrees Fahrenheit but only small amounts of residual radiation. The earlier intense radiation had colored the salt of the cavity wall various shades of blue, green, and violet.
Project GNOME was part of Operation Plowshare. Plowshare was an attempt to use nuclear explosions for peaceful purposes like excavating ditches and canals and mining. Concerns such as blighted land, relocated communities, tritium-contaminated water, radioactivity, and fallout from debris being hurled high into the atmosphere created public opposition to the program and it was terminated in 1977 after $770 million had been spent.
The YouTube video below has a lot of useful information for 9/11 researchers. One minute into the video you see a nuclear explosion.
You can see similar shaped comet trails of dust at the WTC. Chunks of earth turn to dust before landing which is also observed at the WTC as chunks of steel disintegrate before hitting the ground. Judy Wood calls this “dustification” caused by some unknown DEW weapon but here we see the same phenomenon in an early 1960s nuke bomb test.
Pyroclastic cauliflower shaped dust clouds also appear in the video and those type of dust clouds are also observed at the WTC:
Also observed in the video are rows of underground nukes being detonated sequentially. At the WTC they were detonated sequentially from the tops of the buildings to the bottom to simulate a free fall collapse. I heard from a lot of people that was impossible in 2001 yet here in the video we’re seeing it in the early 1960s.
The Plowshare video was produced by the US Atomic Energy Commission. Per Wikipedia: “The AEC was furthermore in charge of developing the United States’ nuclear arsenal, taking over these responsibilities from the wartime Manhattan Project. Over the course of its first decade, the AEC oversaw the operation of Los Alamos Scientific Laboratory, devoted primarily to weapons development, and, in 1952, the establishment of a second weapons laboratory in California (the Lawrence Livermore National Laboratory). It also implemented the “crash” program to develop the hydrogen bomb.”
When looking at who had the technology to pull off the WTC demolitions names to keep in mind include Lawrence Livermore National Laboratory, Los Alamos, Sandia and Oak Ridge – the nuke labs. A lot of the same names you see in the Plowshare video should be familiar to serious 9/11 researchers.
