The Effects of September 11, 2001 Attacks in Aviation: A Study on Human Performance and Behavior in Post 9/11 Era.

This thesis explores the profound impact of the September 11, 2001 terrorist attacks on human performance and behaviour within the aviation industry. The research investigates the multifaceted changes in security protocols, operational procedures, and psychological dynamics that have reshaped the aviation landscape in the post-9/11 era. By employing a mixed-methods approach, combining quantitative data analysis and qualitative interviews with industry professionals, the study examines how heightened security measures and the persistent threat of terrorism have influenced the cognitive and emotional states of aviation personnel, including pilots, cabin crew, and ground staff. The findings reveal significant shifts in stress levels, decision-making processes, and overall job performance, highlighting the need for ongoing support and training to mitigate adverse effects. Additionally, the thesis assesses passenger behaviour and perceptions of safety, evaluating how these factors contribute to the broader security environment. This comprehensive analysis aims to provide valuable insights for policymakers, aviation authorities, and airlines to enhance both security and human performance in an increasingly complex and high-stakes environment.
