And we cannot forget the "nitpicking" about 'into its footprint.' That nit is a very important part to the claim... or the "near freefall speed." If we nail truthers for it, we have to nail fellow debunkers for it.
The discussion about 'into its footprint' did little other than point out that although on the face of it the term is precise, it is however a subjective term in usage. Sure the 'footprint' of a structure is defined by the area of its base and that is the common usage when speaking about intact structures for discussions about the impact of said structure in the urban envoroment. However when one starts using this term when describing a structure that has collapsed by any means at all, whether it be one that succumbed to fire or one that was deliberatly brought down with explosives, its usage ALWAYS becomes subjective. There is no destruction of any building, anywhere(at least I defy anyone to find one) in which the debris is totally confined to the original footprint of the structure.
(long winded but bear with me)
"near free fall speed" is obviously a subjective term and techically incorrect. Free fall in a gravity well is acelleration not speed and the word "near" is a subjective term.
In both cases the 911 conspiracist (or anyone else using these terms) should be taken to task to use correct terminology and to remove as much subjectivity as possible. Unfortunately many 911 conspiracists use highly subjective reasoning. If someone is taken to task about a certain aspect that was described in subjective terms it allows them to simply change what they meant by it.
For eg. the above 'footprint" issue. Demolitions experts will say that they want a building to collapse into its footprint sometimes. They do not expect every stone and mote of dust to do so. Its an exaggeration brought on by the fact that being highly specific about where all the dust and debris will end up is both not possible and even if it were it would take up pages of text to describe ("the 27th brick from the northwest corner of the 3rd floor, 12th layer from floor level will end up 3.7 meters NNE from its original position").
The conspiracist sees that the debris from the WTC towers ended up as far as 500 feet horizontally from its original position and other than dust all of the debris was within this distance from the towers and compares that with what demolitions experts say and concludes that the building technically(because they hear the term used by a technician) fell in its own footprint, and therefore it was a demolition.
The subjective useage of the term allowed for this.
femr2 is quite the opposite though. He delves into deep minutia, did the NW corner move
x cms or
x + 0.1x cms? My beef with this is not that femr is at least being technical, he is, but that he does not bother too much with determining whether or not such minutia is significant. I have also taken issue with some of his methods and descriptions of technical aspects. However there is no need to delve into discussion of them again here.
Fact is that hyperbole, subjective wording, incorrect terminology, and incorrect usage of techical terms should always be pointed out when the debate is to be technical, no matter who does it or whether or not you feel a kinship with that person's viewpoints.
