I would suggest that those who may have a legitimate claim to be scholars are too committed to their treasured models that they claim proove that the towers could not have collapsed on their own. There is also the related issue that there were no measurements taken (temperature, etc.) of the kind that are needed to support their claims, as such these figures can only be estimated.
People like these give real scholars and acadmeics a bad name.[/quote]
No temperature measurements? Wait, this might be a clue - FLOWING MOLTEN STEEL

The observation of molten metal at Ground Zero was emphasized publicly by Leslie Robertson, the structural engineer responsible for the design of the World Trade Center Towers, who reported that “As of 21 days after the attack, the fires were still burning and molten steel was still running.” (Williams, 2001, p. 3; emphasis added.)
Sarah Atlas was part of New Jersey’s Task Force One Urban Search and Rescue and was one of the first on the scene at Ground Zero with her canine partner Anna. She reported in Penn Arts and Sciences, summer 2002, ‘Nobody’s going to be alive.’ Fires burned and molten steel flowed in the pile of ruins still settling beneath her feet. (Penn, 2002; emphasis added.)
Dr. Allison Geyh was one of a team of public health investigators from Johns Hopkins who visited the WTC site after 9-11. She reported in the Late Fall 2001 issue of Magazine of Johns Hopkins Public Health, “In some pockets now being uncovered they are finding molten steel.”

The government reports admit that the building fires were insufficient to melt steel beams – then where did the molten metal come from?
Metals expert Dr. Frank Gayle (working with NIST) stated:
“Your gut reaction would be the jet fuel is what made the fire so very intense, a lot of people figured that’s what melted the steel. Indeed it did not, the steel did not melt.” (Field, 2005; emphasis added.)
None of the official reports tackles this mystery. Yet this is evidently a significant clue to what caused the Towers and WTC 7 to collapse. So an analysis of the composition of the metal is required by a qualified scientific panel. This could well become an experiment crucis.
Prof. Thomas Eagar explained in 2001 that the WTC fires would NOT melt steel:
“The fire is the most misunderstood part of the WTC collapse. Even today, the media report (and many scientists believe) that the steel melted. It is argued that the jet fuel burns very hot, especially with so much fuel present. This is not true… The temperature of the fire at the WTC was not unusual, and it was most definitely not capable of melting steel.” [/i]

Ground Zero’s fires still burning
New Scientist
December 2001
Almost 12 weeks after the terrorist atrocity at New York’s World Trade Center, there is at least one fire still burning in the rubble - it is the longest-burning structural fire in history.

Trade Center Debris Pile Was a Chemical Factory, Says New Study
September 10, 2003
The new work helps explain the very fine particles and extraordinarily high concentrations found by an earlier UC Davis study, the first to identify very fine metallic aerosols in unprecedented amounts from Ground Zero.
“For each of these four classes of pollutant, we recorded the highest levels we have ever seen in over 7,000 measurements we have made of very fine air pollution throughout the world, including Kuwait [oil fires] and China,” Cahill said.

Unit Plans Closed Hearings on Collapse of the Towers
New York Times
12 November 2004
The federal agency investigating the collapse of the World Trade Center said this week that some of its deliberations would take place in secret, including discussions on possible changes to national building codes and standards.
The announcement has been sharply protested by advocates for families of the 9/11 victims, who said they were considering a lawsuit to force the agency to open the meetings to the public.
