A spy plane is an aircraft designed for reconnaissance and intelligence-gathering missions. These planes are equipped with advanced cameras, sensors, and radar systems to collect information about enemy activities, terrain, and other strategic targets. They can operate at high altitudes, making them difficult to detect and allowing them to cover large areas. Spy planes are often used by military forces and intelligence agencies, such as the United States Air Force and the CIA. Notable examples include the U-2 and Global Hawk, which have played significant roles in various conflicts and surveillance operations throughout history.
