Mysterious Drone Swarms Over U.S. Military Bases Remain Unsolved

For 17 days last December, unidentified drones breached restricted airspace over Air Force Base, perplexing officials who are unable to determine their origin.

The drones, some up to 20 feet long, flew at altitudes between 3,000 and 4,000 feet at speeds of 100 mph, appearing each night shortly after sunset.
Despite suspicions of foreign involvement from countries like China or Russia, the drones' origin remains unknown, and hobbyists have been ruled out due to the complexity of the operations.
Federal laws prevent the military from shooting down drones unless they pose an imminent threat, and jamming their signals was deemed too risky due to potential civilian disruptions.
The incidents led to high-level meetings involving the Pentagon, FBI, and White House, but no effective countermeasures have been implemented.
A separate incident involved a Chinese student who pleaded guilty to espionage after using a drone to photograph classified naval installations, highlighting ongoing concerns about foreign surveillance.
