In August of 2001 Mohamed al- Qahtani would arrive in the United States, with the intention of becoming the fifth hijacker of United 93, yet only four terrorists would board the flight on September 11th, 2001.

Earlier in June, the "reluctant hijacker" Ziad Jarrah would enter the country as well, and reportedly would try to leave "the mission" at least twice. Yet he is reported to be the only possible hijacker on board with the ability to fly the plane. We dove into this and so much more in this week's episode.
