What was one of the main outcomes of the Aviation Security Improvement Act of 1990?

The Aviation Security Improvement Act of 1990 was a significant piece of legislation aimed at enhancing the safety and security of civil aviation in the United States, particularly in response to increasing concerns about terrorism. The establishment of the commission on aviation security and terrorism was one of its key outcomes, as it represented a formal acknowledgment by the government of the need to evaluate and improve security measures within the aviation sector. This commission was tasked with examining existing security practices, identifying vulnerabilities, and making recommendations to ensure safer air travel for all passengers.

The establishment of such a commission provided a structured approach to addressing emerging threats and resulted in more stringent security protocols and measures that have shaped the modern aviation security landscape. As a consequence, this act set the stage for subsequent legislation and reforms that continued to evolve aviation security practices, especially in the wake of significant incidents in the years that followed.

The other options reflect developments that are either unrelated to direct security measures or emerged later as industry innovations rather than being direct outcomes of the act itself.
