WTC7 was an 81 vertically columned 47 storied steel framed high rise that dropped into its own footprint in 6.5seconds+or-, 2.25seconds of that in total gravitational freefall. Forensic study found temperatures up to 4,735F[Molybdenum spherules-USGS].FEMA reported Steel vaporized and evaporated with holes in it 'like Swiss cheese'.RJ.LEE found spherical metallic particles 150xnormal building dust,Spheres produced by Molten droplets being violently introduced into air. Independent analysis of DUST found Active Thermitic Material [Harrit/Jones:Bentham] High grade energetics IN the dust.Molten steel was seen in the piles 'running down the channel rails 'like in a foundry'.Eyewitness testimony of explosive events before during and after aircraft strike were established 118 times in audio transcripts.[Barry Jennings.FDNY transcripts]NIST report is a 'probable THEORY',based on computer modeling un-tested by peers or x-examination paradigms not for public disclosure.
