What was the main focus of the Aviation Security Improvement Act of 1990?

The Aviation Security Improvement Act of 1990 primarily aimed to enhance overall security measures within the aviation industry. The focus on stricter regulations surrounding aviation personnel identification systems addressed the need for ensuring that individuals working within airports and airlines have undergone thorough background checks and are adequately vetted to maintain safety and security. By implementing more rigorous identification systems, the act sought to mitigate potential insider threats and strengthen the layers of security that guard against unlawful entry to sensitive areas within airports and aircraft.

While other options touch on important aspects of aviation security, they do not encapsulate the central intent of the act as effectively as the emphasis on personnel identification. For example, while airline ticketing and audits play significant roles in security, the immediate need identified in the 1990 act was more about identifying and verifying the individuals who have access to the operational environment of aviation. Additionally, the development of international aviation agreements, while crucial in context, was not the primary focus of this particular legislative measure.
