The response of the U.S. federal government to the events of September 11, 2001 has reflected the challenge of striking a balance between implementing security measures to deter terrorist attacks while at the same time limiting disruption to air commerce. Airport and Aviation Security: U.S. Policy and Strategy in the Age of Global Terrorism is a comprehensive reference that examines the persistent threats to aviation security that led up to the terrorist attacks of September 11th, describes subsequent terror plots against aviation assets, and explores U.S. efforts to counter and mitigate these threats.
