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 Out", at 53:20 here: As recently as March, 2018, one of the key AE911Truth engineers repeated the claim as fact: Having found no rebuttal of Szamboti's premise, it seems appropriate, for the record, to submit a thread on the topic. The assertion is patently false, easily discernible by studying collapse initiation from east or west. I used a video taken from the west, on the Hudson river: It's clear the tower top section and antenna are tilting south as one unit to begin collapse. The motion indicates that the core initially served as the fulcrum for the rotating motion of the tower top, buckled, and was quickly ripped apart. A closer look shows clearly the antenna did not drop into the building: Gage and Szamboti use only a view from the north, the optics of which are illustrated here: Editorial comment: It is unfathomable that professional architect and engineer researchers would fail to study initiation of collapse from all angles. Initiation, or onset, is actually all that matters in determining why a structure collapsed. It is clear onset of the North Tower was due to failure of the south wall, not the core. The south wall gradually formed an inward sink, long before onset of collapse, seen below, and there is no sign of core failure until after the tower top started tilting south. For Gage and Szamboti to still claim the core failed first reveals utter sloppiness, or outright bias/deceit, neither worthy of the "Truth" moniker.
