A Line Is Drawn. Part Four. From a documentary about the NATO Air Defence Ground Environment system (NADGE)

The transcript describes NATO's air defense system, which uses radars and computers to detect and respond to potential threats. Allied aircraft from 11 NATO nations tested the system, which involves detecting unknown aircraft, verifying their identity, and intercepting them if necessary. The system can also coordinate missile and fighter responses in the event of an attack. Training exercises demonstrate collaboration among NATO countries, with real-time examples of interception and identification procedures.
