Around 6:00 in the evening on 9/11 ABC's Lynn Sherr gave a rundown of the airplanes and number of passengers. Somehow, she knew that the hijackers were not included in the passenger lists or statistics she was given.

"Total number of passengers and crew, two hundred and sixty-six people, not (of course) counting the hijackers"

How does she know that the hijackers are not included in the 266?

Maybe someone can tactfully ask her.
