Chilean Navy pilots and radar operators reported tracking multiple unidentified aerial phenomena exhibiting synchronized movement, abrupt acceleration, and no detectable infrared signature during a coastal patrol mission.
On November 16, 2007, Chilean Navy personnel conducting routine coastal operations off Antofagasta reported detecting multiple unidentified objects both visually and via radar. The objects reportedly moved in coordinated formations and demonstrated flight characteristics inconsistent with known aircraft. Infrared sensors failed to detect expected heat signatures, and no conventional propulsion systems were observed. The incident was later analyzed by Chilean military authorities and remains one of South America's most well-documented UAP cases.
