The last of the 20 9/11 hijackers arrives in the US: Saudi Mohammed al-Kahtani. He landed in Orlando, but immigration officials refused to let him pass because he had a one-way ticket, didn’t speak English, and couldn’t explain what he was doing in the United States. He wasn’t replaced by Al Qaeda, and Flight 93, the one that crashed in Pennsylvania, had only four attackers, not five like the other three hijacked flights.
