This podcast from Transport Security International Magazine examines the history of aviation security and argues that it is not merely reactive to events, but rather a constantly evolving process of transformation. The author, James Marriott, who has decades of experience in aviation security, highlights several key events that have shaped the industry, including the Air India bombing in 1985, the Lockerbie bombing in 1988, and the September 11th attacks. These events have spurred significant improvements in security measures, technology, and international cooperation. Marriott argues that while hindsight may make it seem like security measures were reactive, they were in fact the result of ongoing analysis and adaptation to evolving threats. He concludes by urging professionals to be prepared for future transformative events by having proactive transformation plans in place.
