"The security and economic prosperity of the United States depend significantly upon the secure operation of its aviation system and use of the world's airspace by the Nation, its international partners, and legitimate commercial interests. Terrorists, criminals, and hostile nation-states have long viewed aviation as a target for attack and exploitation. The tragic events of September 11, 2001 and the Heathrow plot of August 2006 are telling reminders of the threats facing aviation and the intent and capabilities of adversaries that mean to do harm to the United States and its people. In June 2006, building upon the Administration's successful efforts since 9/11, the President directed the development of a comprehensive National Strategy for Aviation Security (hereafter referred to as 'the Strategy') to protect the Nation and its interests from threats in the Air Domain. The Secretary of Homeland Security, in accordance with National Security Presidential Directive 47/Homeland Security Presidential Directive 16 (NSPD-47/HSPD-16), will coordinate the operational implementation of the Strategy, including the integration and synchronization of related Federal programs and initiatives. […] Through a collaborative interagency effort and with input from aviation stakeholders, seven supporting plans will be developed to address the specific threats and challenges identified in NSPD-47/HSPD-16. Although the plans will address different aspects of aviation security, they will be mutually linked and reinforce each other. The supporting plans are: Aviation Transportation System Security Plan, Aviation Operational Threat Response Plan, Aviation Transportation System Recovery Plan, Air Domain Surveillance and Intelligence Integration Plan, International Aviation Threat Reduction Plan, Domestic Outreach Plan, and International Outreach Plan."
