Claim: Jim Hoffman's "9/11 progressive collapse challenge" can't be met
Many years ago, Jim Hoffman issued a "progressive collapse challenge" on his 9-11 Research website (see quote below). "If [the WTC's] mode of structural failure is so likely to happen," he asked, "why is it so difficult to reproduce?" At the time, his target was "pancake collapse", not the ROOSD... -
False Narrative: "North Tower Antenna Dropped Before Roof Line"
Richard Gage's AE911Truth organization asserts the North Tower antenna dropped straight down into the building at the beginning of collapse, and claims that is evidence the core columns had to be cut with cutter charges. The claim is made in the video, "9/11 Explosive Evidence - Experts Speak... -
Debunked: "The North Face of Building 7 Was Pulled Inward"
INTRODUCTION [Arthur Scheuerman in his book "Fire in the Skyscraper" postulated] the mysterious "kink" in the north face of Building 7 was the result of collapsing core columns pulling the north face inward: http://www.crono911.net/docs/ScheuermanWTC7a.pdf Most researchers seem to concur, at... -
Debunked: The WTC 9/11 Angle Cut Column. [Not Thermite, Cut Later]
This image is famous in 9/11 conspiracy culture: The column in the center of the photo (by Sam Hollenshead) has been cut at an angle, presumably during the cleanup process. Yet Architects and Engineers for 9/11 Truth (AE911) still insist it was cut before the building fell, and looks nothing... -
Huntley Hotel Fire in Santa Monica vs. WTC2 "Molten Metal"
A minor fire, quite small, but interesting from the perspective of 9/11 in that it was high-rise building that was dripping orange embers. Source: https://twitter.com/gclaude746/status/939705800951336960 The 9/11 comparison is with the claim that there was "molten metal" falling from a... -
Explained: "Smoke Trails" On 9/11 World Trade Center Falling Debris [Dust/Powder]
When the World Trade Center towers collapsed they produced many tons of dust, powder, and granular material. This was from two main sources: drywall and concrete. After the initial collapse the bottom half of the core of the building was still standing. It was covered in tons of this material... -
WTC Towers Core Columns - What Held Them Together? Welds.
The core columns of the world trade center were incredibly strong box columns with inches thick walls. But most of their strength was just for support. They were not designed to be resist much lateral forces. It seems they largely came apart where they were joined at the ends. But what actually... -

Kinematic production of molten steel and its cooling rate
Hi everyone, As we all know jet fuel can't melt steel beams. Of course melting steel beams is unnecessary to explain the collapse of WTC 1 or 2. But then truthers will point to the various witness statements talking of "molten steel" or "molten metal" in the WTC basements. This topic has...
