Why Did the 9/11 Hijackers Favor Cross-Country Flights?

" "

The September 11, 2001 (9/11) attacks were meticulously planned to maximize the havoc and psychological impact on the United States. One of the strategic choices made by the hijackers was to select cross-country flights over shorter ones. This decision was not random, but rather based on several considerations related to flight duration, passenger capacity, fuel load, target selection, and security protocols. In this article, we delve into the rationale behind these choices and explore why cross-country flights played a crucial role in the successful execution of the 9/11 attacks.

Longer Flight Duration

" "

The hijackers chose cross-country flights because of their longer duration, which provided them with more time in the air to implement their plans. This extended period was critical for overruling the aircraft and conducting the subsequent attacks. The longer flight times allowed the terrorists to maintain control of the planes and ensure that they reached their intended targets without interruption. Additionally, the extended duration gave them ample time to prepare their attacks and to coordinate with each other as the flights progressed.

Passenger Capacity

" "

Cross-country flights often have higher passenger capacities compared to shorter flights. This meant that the hijackers could affect a larger number of people, thereby maximizing the psychological and media impact of the attacks. By choosing flights with more passengers, the hijackers were able to ensure that the attacks would have a wider reach and greater impact on the public consciousness. Furthermore, a higher number of passengers would complicate evacuation efforts and amplify the panic and chaos on the ground.

Fuel Load

" "

The hijackers needed to transport a significant amount of fuel to guarantee that their planes would have enough power to reach their targets and cause maximum damage upon impact. Many of the flights selected for the attacks were 757s and 767s, which carried substantial fuel loads. Full fuel tanks were essential because the planes had to cover long distances and endure the flight’s duration without refueling. The choice of these aircraft, particularly their larger fuel capacities, was a critical factor in the success of the hijackers' plans.

Target Selection

" "

The hijackers carefully selected cross-country flights that would reach high-profile targets such as the World Trade Center and the Pentagon. These iconic buildings were symbolic of American economic and military power, making their destruction highly significant. The specific flights chosen included American Airlines Flight 11, United Airlines Flight 175, American Airlines Flight 77, and United Airlines Flight 93. Each of these flights offered pathways to these critical targets, ensuring that the hijackers could carry out their attacks and achieve their objectives.

" "

Security Considerations

" "

The hijackers likely believed that longer flights would have fewer security checks and less stringent protocols. These flights typically had more time for passengers to board, which made it easier for the hijackers to blend in with the crowd and conduct their operations undetected. The extended duration of the flights gave them an advantage in terms of time, allowing them to carry out their preparations and execute the attacks with minimal interference.

" "

Logistical and Operational Factors

" "

Cross-country flights typically depart early in the morning and have fewer passengers than normal flights. This timing and the reduced passenger count played perfectly into the hijackers' schedule and plan. For example, only one of the planes, American Airlines Flight 11 bound for the North Tower, was more than half full. A smaller number of passengers made it easier to subdue them and control the situation on the aircraft. Additionally, the longer flights required more fuel, which resulted in more extensive fires and fatalities upon impact with the targets.

" "

At the time of the attacks, longer flights were often dominated by larger wide-body aircraft like the 757 and 767, whereas short flights used smaller narrow-body planes like the 737 and MD-80. The choice of wide-body aircraft was strategic, as these planes were heavier and could cause more damage upon impact. The 767, with its twin aisles, made it easier for the hijackers to breach the cockpit and gain control of the plane.

" "

Today, the landscape of commercial aviation has changed, with larger 737 variants and A321s replacing the older models. However, the aircraft used in the 9/11 attacks were among the heaviest, with empty weights comparable to fully-laden MD-80s and 737s. The weight of these aircraft contributed to the severity of the impacts and the subsequent fire damage. The hijackers’ choice of these heavier aircraft was a calculated decision that maximized the destructive potential of their attacks.

Conclusion

" "

The hijackers' selection of cross-country flights was a carefully considered strategy that played a significant role in the success of the 9/11 attacks. Their choice of flights with longer durations, higher passenger capacities, appropriate fuel loads, ideal target selection, and strategic timing and planning were all critical factors. By understanding these aspects, we can gain a deeper insight into the tactical decisions made by the hijackers and the broader context of the attacks.
