Considered the definitive handbook on the terrorist threat to commercial airline and airport security, Colonel Kathleen Sweet's seminal resource is now updated to include an analysis of modern day risks, as well an examination of the plethora of changes made to air security policies, practices, and regulations since 9/11. She covers the history of aviation security and compares current in-flight security practices with those of other countries. In addition to cargo and passenger security, the text looks at airport and aviation business practices and how security considerations are factored into business processes. New regulations for the Transportation Security Administration are also detailed.
