Kevin Barrett believes the U.S government might have destroyed the World 
Trade Center. Steven Jones is researching what he calls evidence that the twin 
towers were brought down by explosives detonated inside them, not by hijacked 
airliners. 
These men aren't uneducated junk scientists: Barrett will teach a class on 
Islam at the University of Wisconsin this fall, over the protests of more than 
60 state legislators. Jones is a tenured physicist at Brigham Young University 
whose mainstream academic job has made him a hero to conspiracy theorists. 
Five years after the terrorist attacks, a community that believes widely 
discredited ideas about what happened on Sept. 11, 2001, persists and even 
thrives. Members trade their ideas on the Internet and in self-published papers 
and in books. About 500 of them attended a recent conference in Chicago. 
The movement claims to be drawing fresh energy and credibility from a 
recently formed group called Scholars for 9/11 Truth. 
The organization says publicity over Barrett's case has helped boost 
membership to about 75 academics. They are a tiny minority of the 1 million 
part- and full-time faculty nationwide, and some have no university affiliation. 
Most aren't experts in relevant fields. But some are well educated, with degrees 
from elite universities such as Princeton and Stanford and jobs at schools 
including Rice, Indiana and the University of Texas. 
"Things are happening," said co-founder James Fetzer, a retired philosophy 
professor at the University of Minnesota Duluth, who maintains, among other 
claims, that some of the hijackers are still alive. "We're going to continue to 
do this. Our role is to establish what really happened on 9/11." 
What really happened, the national Sept. 11 Commission concluded after 1,200 
interviews, was that hijackers crashed planes into the twin towers. The National 
Institute of Standards and Technology, a government agency, filed 10,000 pages 
of reports that found fires caused by the crashing planes were more than 
sufficient to collapse the buildings. 
The scholars' group rejects those conclusions. Their Web site contends the 
government has been dishonest. It adds: the "World Trade Center was almost 
certainly brought down by controlled demolitions" and "the government not only 
permitted 9/11 to occur but may even have orchestrated these events to 
facilitate its political agenda." 
The standards and technology institute, and many mainstream scientists, won't 
debate conspiracy theorists, saying they don't want to lend them unwarranted 
credibility. 
But some worry the academic background of the group could do that anyway. 
Members of the conspiracy community "practically worship the ground (Jones) 
walks on because he's seen as a scientist who is preaching to their side," said 
FR Greening, a Canadian chemist who has written several papers rebutting the 
science used by Sept. 11 conspiracy theorists. "It's science, but it's 
politically motivated. It's science with an ax to grind, and therefore it's not 
really science." 
Faculty can express any opinion outside the classroom, said Roger Bowen, 
general secretary of the American Association of University Professors. However, 
"with academic freedom comes academic responsibility. And that requires them to 
teach the truth of their discipline, and the truth does not include conspiracy 
theories, or flat Earth theories, or Holocaust denial theories." 
Members of the group don't consider themselves extremists. They simply 
believe the government's investigation was inadequate, and maintain that 
questioning widely held assumptions has been part of the job of scholars for 
centuries. 
"Tenure gives you a secure position where you can engage in controversial 
issues," Fetzer said. "That's what you should be doing." 
But when asked what did happen in 2001, members often step outside the 
rigorous, data-based culture of the academy and defer to their own instincts. 
Daniel Orr, a Princeton Ph.D. and widely published retired economics chair at 
the University of Illinois, said he knew instantly from watching the towers fall 
that they had been blown apart by explosives. He was reminded of watching an old 
housing project being destroyed in St. Louis. 
David Gabbard, an East Carolina education professor, acknowledges this isn't 
his field, but says "I'm smart enough to know ... that fire from airplanes can't 
melt steel." 
When they do cite evidence, critics such as Greening contend it's junk 
science from fellow conspiracy theorists, dressed up in the language and format 
of real research to give it a sense of credibility. 
Jones focuses on the relatively narrow question of whether molten metal 
present at the World Trade Center site after the attacks is evidence that a 
high-temperature incendiary called thermite, which can be used to weld or cut 
metal, was involved in the towers' destruction. He concludes thermite was 
present, throwing the government's entire explanation into question and 
suggesting someone might have used explosives to bring down the towers. 
"I have not run into many who have read my paper and said it's just all 
hogwash," Jones said. 
Judy Wood, until recently an assistant professor of mechanical engineering at 
Clemson University, has been cited by conspiracy theorists for her arguments the 
buildings could not have collapsed as quickly as they did unless explosives were 
used. 
"If the U.S. government is lying about how the buildings came down, anything 
else they say cannot be believed," she said. "So why would they want to tell us 
an incorrect story if they weren't part of it?" 
In fact, say Greening and other experts, the molten metal Jones cites was 
most likely aluminum from the planes, and any number of explanations are more 
likely than thermite. 
And the National Institute of Standards and Technology's report describes how 
the buildings collapsed from the inside in a chain reaction once the floors 
began falling. 
"We respect the opinions of others, but we just didn't see any evidence of 
what people are claiming," institute spokesman Michael Newman said. 
Wisconsin officials say they do not endorse the views of Barrett, an adjunct, 
but after investigating concluded he would handle the material responsibly in 
the classroom. 
That didn't mollify many state legislators. 
"The general public from Maine to Oregon knows why the trade towers went 
down," said state Rep. Stephen Nass, a Republican. "It's not a matter of 
unpopular ideas; it's a matter of quality education and giving students their 
money's worth in the classroom." 
In a July 20 letter obtained by The Associated Press in an open records 
request, Wisconsin Provost Patrick Farrell warned Barrett to tone down his 
publicity seeking, and said he would reconsider allowing Barrett to teach if he 
continued to identify himself with the university in his political messages. 
BYU's physics department and engineering school have issued statements 
distancing themselves from Jones' work, but he says they have not interfered. 
At Clemson, Wood did not receive tenure last year, but her former department 
chair, Imtiaz ul Haque, denies her accusation that it was at least partly 
because of her Sept. 11 views. 
"Are you blackballed for delving into this topic? Oh yes," Wood said. "And 
that is why there are so few who do. Most contracts have something to do with 
some government research lab. So what would that do to you? The consequences are 
too great for a career. But I made the choice that truth was more important." 
"If we're in higher education to be trying to encourage critical thinking," 
Wood says, "why would we say 'believe this because everybody else does?'"
