Which two organizations are responsible for the physical search of the contiguous U.S. and maritime region?

The Coast Guard and Air Force are responsible for the physical search of the contiguous U.S. and the maritime region due to their specific missions and capabilities. The Coast Guard has a primary role in maritime safety, security, and environmental protection, making it crucial for operations conducted in coastal areas and marine environments. Their responsibilities include search and rescue missions as well as monitoring for illegal activities at sea.

The Air Force supports these efforts through its capabilities in aerial reconnaissance and support during search and rescue operations. Their ability to cover vast areas quickly with aircraft complements the Coast Guard's maritime operations, allowing for efficient searches and responses in both land and sea contexts.

Other organizations mentioned, such as the FBI, primarily focus on law enforcement and criminal investigations and are not typically involved in search operations at a physical level. The FAA's role is centered on aviation safety and air traffic control rather than physical search and rescue operations within the national security framework.
