What measures were taken to enhance security in international airports during the period of 1980-1990?

During the period of 1980-1990, many international airports significantly increased their security measures in response to various incidents, including high-profile hijackings and terrorist attacks. The choice of heavy guarding by tactical police wearing body armor reflects a proactive approach to enhancing safety and security within airport environments.

By employing highly visible, heavily armed tactical police, airports aimed to both deter potential threats and ensure a rapid response capability in the event of an incident. This level of security is indicative of the emerging understanding of threats that airports faced during this period, highlighting a shift toward a more militarized and robust security posture. The presence of tactical units not only served to protect passengers and airport staff but also to reassure the traveling public about their safety.

The other options are less aligned with the significant security enhancements observed during this time. For instance, unarmed security staff monitoring only would not provide the necessary deterrence or response capability required for the threats experienced in that decade. Similarly, reducing surveillance technology would be counterproductive, as advanced monitoring systems became essential for early threat detection. Limiting access to authorized personnel was implemented, but it was part of a broader strategy that included visible and armed law enforcement, underscoring the need for an integrated security approach.
