Terral Lee Croft
General Contractor / Demolition Supervisor
Bio: General Contractor Experience, 30 years' experiencePersonal 9/11 Statement:
"My father and his father were General Contractors proficient in demolition and new construction and I am the product of their combined experience. I designed and built my first commercial building at the tender age of twenty-two years old.
WTC-7 was built using Compartmentalization of all supporting columns, beams and girders using solid concrete slabs (horizontal) and curtain walls (vertical), which disqualifies 'fire' from being the cause of this collapse. The columns were encased in gypsum wallboard and/or coated with 3-hour 'spray on' protective insulation. Typical building fires burn at around 800 degrees, but the red iron in WTC-7 requires 2800 degrees to begin melting. There is no way 'all' of the steel supports were severed by any fire in just a few hours, unless controlled demolition was carefully planned and executed by demolition specialists. Building fires typically burn in one area for about 20 minutes, before the fuel is extinguished, which is why no steel-framed skyscraper has ever burned down before or after 9/11."

Bio: Licensed A & P mechanic. U.S. Army Reserve, Combat Engineer, Specialized in Demolitions, Honorable Discharge.
Personal 9/11 Statement:
"In the Army Reserves I was trained in demolitions so I know what it takes to bring down a building in a controlled symmetrical fashion and what it looks like when it happens. As an aircraft mechanic, my knowledge of the properties of fuels, specifically Jet fuel (or highly refined kerosene), brings the conclusion that fires couldn't be hot enough to cause symmetrical structural collapse. Based on what I know, looking at it from various disciplines, it's obvious that all three WTC buildings collapsed due to pre-planned, well placed, precisely timed controlled demolitions."

John Suffoletta
Journeymen Operating Engineer
Bio: demolition of steel and concrete buildings, also some wood structures
Personal 9/11 Statement:
I believe I have the experience to know the difference between an implosion or a building consumed by fire to the point of collapse. I actually run the equipment that rips and tears these buildings down, and I know what it takes! A building consumed with fire would droop , contort and lean to the weakest point before falling! It would not fall straight to the ground in nice net truck length pieces, with the concrete almost completely pulverized.
