This podcast from an excerpt from Transport Security International Magazine reflects on the 20th anniversary of the 9/11 terrorist attacks and their lasting impact on the aviation industry. The piece examines the significant security measures implemented following the attacks, as well as the economic devastation they caused. The author, Willie Walsh, director general of the International Air Transportation Association (IATA), argues that the industry has learned valuable lessons from these crises, particularly the need for more nuanced and risk-based security measures, and draws parallels to the current challenges posed by the COVID-19 pandemic.
