WTC7 mechanism: NIST fire vs Hulsey not-fire
2008-11-20 · NIST NCSTAR 1A
WTC 7 collapsed from fire-induced buckling of Column 79 after debris from WTC 1 started fires.
EVD-1062020-03-01 · Hulsey et al., UAF
Fire did not cause the observed collapse; near-simultaneous column failure is required.
EVD-123Direct engineering contradiction. Funding of Hulsey by AE911Truth is a quality factor, not a reason to hide the paper.

Pentagon: AA77 vs no-Boeing
2004-07-22 · Commission / NTSB / ASCE
AA77, a Boeing 757, struck the Pentagon at 09:37:46 along an NTSB path with ASCE-mapped interior damage.
EVD-1162009-01-01 · CIT and related
Selected witnesses and façade photographs mean a 757 did not hit the building.
EVD-148Quality-weighted, A currently dominates. B stays because the user instruction is not to hide labelled claims.

Bayoumi's intelligence role: Commission 2004 vs FBI 2017
2004-07-22 · 9/11 Commission Report, Ch. 7
No credible evidence Bayoumi knowingly aided extremists; unlikely clandestine candidate.
EVD-0052017-06-14 · FBI report 14 June 2017 (EO 14040)
Allegations of Bayoumi's Saudi intelligence involvement were not confirmed at Commission time; the 2017 information confirms them. He was a paid GIP cooptee.
EVD-010Hard contradiction on intelligence-officer status. Does not automatically resolve plot knowledge.

WTC 7 Stage 1: NIST gradual vs Chandler instantaneous whole-roofline free fall
2008-11-20 · NIST NCSTAR 1A / FAQ
NIST Stage 1: acceleration less than g as buckling progressed, measured at one north-face centre point, then Stage 2 free fall.
EVD-1072023-06-01 · Journal of 9/11 Studies, June 2023
Chandler/Walter/Szamboti 2023: most of the north and west rooflines stayed still ~1.4 s, then the entire measurable roofline entered free fall together within ~0.2 s — a transition they say NIST's Stage 1 hides.
EVD-208Same building, same free-fall stage, different description of the onset and of how much of the roofline moved. Measurement dispute, then interpretation.

NORAD first story vs NORAD tapes

Early NORAD public and May 2003 testimony described a more capable, earlier-notified defence.
EVD-1042006-08-01 · Vanity Fair tapes / Farmer
NEADS tapes and Commission counsel show a phantom AA11, late notice, and that some accounts were not true.

WTC dust chips: thermite vs primer paint
2009-04-03 · Harrit et al. 2009
Red/gray chips are unreacted thermitic material; DSC exotherms ~430°C; iron-rich spheres after ignition.
EVD-1212019-11-20 · NIST FAQ / paint-chemistry critics
Chips are consistent with primer paint / known coatings; NIST found no corroborating thermite evidence.

CIT and related no-Boeing claims: a 757 did not hit the Pentagon.

Wyndham 2011 and Legge & Stutt 2011, in the Journal of 9/11 Studies, support a large-plane / official AA77 path.

EVD-0152012-09-11 · Toronto Report ch.5
Fenton/Scott: a small Alec Station group withheld the information intentionally, and after summer 2001 the purpose was to allow the attacks.

Silverstein 'pull it': demolition vs firefighter withdrawal
2002-09-10 · PBS America Rebuilds
He said pull it and they made that decision to pull and watched the building collapse — demolition slang.
EVD-1242005-01-01 · Silverstein Properties clarification
Pull meant withdraw firefighters; the collapse was not an ordered demolition.
EVD-125Authentic utterance; competing lexicons. Do not treat either reading as a confession or a nothing.

WTC7 free fall: NIST consistency vs demolition signature

A 2.25-second free-fall stage is consistent with NIST's exterior-column buckling model.
EVD-1072008-11-20 · AE911Truth / independent physics arguments
Free fall through a steel high-rise indicates simultaneous support removal, i.e. explosives.
