The truth remains very clear to the FDNY, as my links to their many eyewitness statements clearly indicate.  The truth also hasn't eluded the Local 40 & 361 Iron Workers who erected all 3 collapsed WTC hi-rises and spent nearly 8 months removing all of their debris steel after the al Qaeda suicide attacks of 9/11/2001, nor do the ~40,000 other cleanup personnel who cleared debris from the WTC site at one time or another during that time period have any problem with it.
 I've posted no "responses in an attempt to cloud the truth," and have actually done quite the opposite. If secret explosive (or incendiary) demolitions of occupied and secured Lower Manhattan office hi-rises are possible, let's see real evidence of it, not some guy dropping empty cardboard boxes and lying about collapse times.
Talk's cheap. No need to breach security, rip out column enclosures and SFRM; just get a ~4' length of W14 X 730 and go for it -- on video, with audio.
