This podcast from Transport Security International Magazine examines aviation security in the twenty years since the 9/11 attacks. It focuses on how, Philip Baum, explores various security threats to aviation, ranging from traditional terrorism and hijacking to insider threats, airport attacks, and mental health issues. It examines the effectiveness of post-9/11 security measures and argues for a more holistic approach that considers the broader context of global conflicts, societal pressures, and evolving terrorist tactics. Also, highlights the need to remain vigilant in the face of ever-evolving security challenges, especially as the aviation industry recovers from the COVID-19 pandemic.
