Fox News claims that up to 12 other Middle Eastern men dressed in pilot uniforms were on other flights scheduled to take off on the morning of 9/11. Hijackings on all these flights were foiled when an unexpected ban on new flights prevented them from taking off. An FBI source says they had been invited into the cockpits under the impression that they were guest pilots from other airlines. It is standard practice to give guest pilots the spare seat in the cockpit known as the jump seat. [Fox News, 9/24/2001] Flight 93’s cockpit voice recording has apparently shown that “one of the four hijackers had been invited into the cockpit area before the flight took off.” Many pilot uniforms had gone missing prior to 9/11. It is claimed that Mohamed Atta was given a guided tour of Boston’s Logan Airport the week before 9/11 when he turned up in a pilot uniform saying he was with Saudi Airlines.
