A quarter-century has passed since the September 11, 2001 terrorist attacks, in which al-Qaeda operatives hijacked four commercial aircraft that crashed into the World Trade Center towers and the Pentagon. But a new investigation by TMZ raises a lingering question from that morning: was there a fifth flight targeted for hijacking that only by chance failed to take off?
The investigation focuses on United Airlines Flight 23, scheduled to depart New York's JFK Airport for Los Angeles around 9:00 a.m. that morning. The aircraft had already begun taxiing toward the runway when it encountered delays due to congestion. During the wait, the hijacked planes struck the Twin Towers, prompting authorities to close American airspace and order Flight 23 back to the gate.
The pilot and three flight attendants interviewed for the investigation described several passengers who raised their suspicions even before departure. One appeared unusually nervous and was sweating profusely, while a group of four passengers in first class repeatedly insisted the plane take off immediately. According to crew testimony, one of them even requested access to the cockpit, claiming a child in their party wanted to see it.
Suspicions intensified after the aircraft was evacuated. Ground crew reported seeing people in uniforms inside the plane, even though it was supposed to be empty and locked. Investigators later discovered that a floor hatch leading to the area beneath the passenger cabin had been left open. Crew members said the FBI questioned them the very next day, and flight attendants participated in a lineup attempting to identify the suspicious passengers.
Box cutters, similar to those used by the 9/11 hijackers, were reportedly found hidden in first-class seat pockets on another aircraft parked nearby, which had a tail number similar to Flight 23. The pilot raised the possibility that the weapons were actually intended for his plane but were planted on the wrong aircraft by mistake. "I now believe it's more likely than not that we were the fifth plane," said Captain Tom Mannello.
Despite the testimony and investigation, there remains no official confirmation that Flight 23 was part of the September 11 plot. The official 9/11 Commission did not determine that a fifth plane was involved, and the claim regarding this flight remains a theory.
But for the crew members who were aboard that morning, the seemingly routine delay on the runway continues to raise a question twenty-five years later: did it prevent another disaster?
