I would love to hear that one of you guys won this prize. From Reuters:

NEW YORK (Reuters) – Jimmy Walter has spent more than $3 million promoting a conspiracy theory the Sept. 11, 2001, attacks on the United States were “an inside job” and he is offering more cash to anyone who proves him wrong.
The millionaire activist is so convinced of a government cover-up he is offering a $100,000 reward to any engineering student who can prove the World Trade Center buildings crashed the way the government says.
“Of course, we expect no winners,” Walter, 57, heir to an $11 million fortune from his father’s home-building business, said in a telephone interview from California on Wednesday. He accuses figures in government, the military and business of involvement in the Sept. 11 attacks.
Walter said a panel of expert engineers would judge submissions from the students.
Next month, he also launches a nationwide contest seeking alternative theories from college and high school students about why New York’s World Trade Center collapsed. The contest offers $10,000 to the best alternative theory, with 100 runner-up awards of $1,000. Winners will be chosen next June.
The World Trade Center’s twin towers were destroyed after hijackers from Osama bin Laden (news – web sites)’s al Qaeda militant group slammed two commercial airliners into them. The attack in New York killed 2,749 people.
Various official investigations give no credence to Walter’s theory. A Sept. 11 commission spokesman said its policy was not to comment on criticism of the report.
Walter insists there had to be explosives planted in the twin towers to cause them to fall as they did, and also rejects the official explanation for the damage done at the Pentagon (news – web sites).
“We have all the proof,” said Walter, citing videotapes and testimony from witnesses.
“It wasn’t 19 screw-ups from Saudi Arabia who couldn’t pass flight school who defeated the United States with a set of box cutters,” he said. He dismissed the official Sept. 11 commission report, saying, “I don’t trust any of these ‘facts.”’
