According to Corsi , " A video clip widely circulated on the Internet shows a test that pulverized an F-4 fighter on impact with a hardened target , providing evidence to answer members of the 9/11 Truth movement who question why so little identifiable airplane debris remained after the hijacked American Airlines Boeing 757 hit the Pentagon . " Audio and a YouTube video were circulated , especially among those questioning the credibility of Corsi 's January 29 , 2008 interview on Alex Jones 's radio show . In the interview Corsi discussed " the findings of Steven Jones , physicist and hero of the 9/11 Truth movement who claims to have evidence that the World Trade Center towers collapsed due to explosives inside the building , not just the planes hitting them , during the attacks " . Corsi cited Jones 's findings of microscopic forensic evidence that seemingly negated the U.S. government hypothesis that the aircraft 's jet fuel-fed heat alone was sufficiently hot to collapse the steel superstructure of the buildings
