Fifth 9/11 Plane Investigated as Terrorist Target: ‘Suspicious and Alarming Activities’

A United Airlines flight crew is coming forward with what they say could’ve been a close call on 9/11.

Members of the flight’s crew said their Boeing 767 aircraft could’ve been the target of an attempted, fifth hijacking attempt.

Flight 23, slated to fly from John F. Kennedy Airport in New York to Los Angeles International Airport, averted takeoff when an air traffic controller learned of the attack on the World Trade Center.

Members of the flight’s crew recounted bizarre interactions with passengers on board the ultimately grounded flight before takeoff, speaking in a new TMZ documentary “TMZ Investigates: 9/11: The Fifth Plane.” The full documentary will be released on Monday.

TMZ said it investigated the “suspicious” activities that took place before the flight’s takeoff for six months.

The flight crew recounted passengers behaving bizarrely in the first class segment of the plane before takeoff — including one person wearing an Islamic hijab, whom crew members believed was impersonating a woman, according to the New York Post.

The suspicious passengers urged crew to take off, instigating an argument with their impatience.

The crew members said another passenger in business class was sweating profusely, according to the Post.
