The Air Force recently initiated a program to create an integrated air defense system throughout Latin America, similar to the program started in Eastern Europe after the Cold War. The goals are to modernize airspace management and improve safety through a continuous air picture, updated with real-time flight track and flight plan data using civil and military resources, and to increase regional cooperation and interoperability. If given a higher priority and dedicated resources, this timely initiative could make a significant contribution to the creation of the Mexico-Caribbean Basin Surveillance System.
