The plane Hijacking That Changed American Aviation Forever

9/11: How Four Hijacked Flights Changed Aviation Forever On September 11, 2001, four coordinated hijackings exposed decades of assumptions built into American aviation security and triggered the most sweeping reforms in modern aviation history. This documentary follows the hijackings of American Airlines Flights 11 and 77, United Airlines Flights 175 and 93, minute by minute, before examining the investigations and security changes that reshaped air travel. We explore the "Common Strategy" that instructed flight crews to comply with hijackers, the Government Accountability Office report that warned of critical screening failures months before the attacks, the creation of the Transportation Security Administration (TSA), the introduction of reinforced cockpit doors, the expansion of the Federal Air Marshal Service, and the evolution of passenger screening programs. Built entirely from the 9/11 Commission Report, U.S. Government Accountability Office investigations, congressional records, and other official sources, this episode focuses on how aviation security changed after September 11 and the lasting impact those reforms continue to have on air travel today.
