Aerial espionage refers to the use of aircraft, drones, or satellites to gather intelligence from above. This method allows for the observation of military activities, infrastructure, and other sensitive locations without direct contact. It is often employed by governments and intelligence agencies to monitor potential threats and assess enemy capabilities. The technology used in aerial espionage includes high-resolution cameras, radar systems, and electronic surveillance equipment. Notable examples include the use of UAVs (unmanned aerial vehicles) and reconnaissance satellites to collect data. This practice plays a crucial role in modern military strategy and national security efforts.
