“On August 4, 2001, Mohamed al Kahtani was denied U.S. entry at Orlando International Airport. On September 11, 2001, while three planes carried five hijackers, United Flight 93 carried only four. These four were overpowered by passengers, sparing a potential target in Washington. Federal investigators believe that al Kahtani was meant to be Flight 93’s fifth hijacker.Why did Immigration and Naturalization Service inspector Jose Melendez-Perez turn away al Kahtani on August 4?
