This All-domain Anomaly Resolution Office (AARO) case resolution from the U.S. Department of Defense is dated February 2025. It covers the "Go Fast" FLIR video, which a U.S. Navy F/A-18F recorded off Florida in January 2015. AARO found the object was at about 13,000 feet and moving between 5 and 92 mph once wind is accounted for. It assesses with high confidence that the object showed no anomalous performance and attributes the apparent high speed to motion parallax. A technical appendix explains the calculations.
UNCLASSIFIED UNCLASSIFIED All-domain Anomaly Resolution Office U.S. Department of Defense Case: “Go Fast” Case Resolution | February 6, 2025 Case Overview In January 2015, a U.S. Navy F/A-18F pilot recorded an object using a Forward Looking Infrared (FLIR) sensor about 13,000 feet above the Atlantic Ocean off the coast of Florida. The video appeared to show the object moving at high speed. AARO cannot definitively identify the object, but it displayed no anomalous performance characteristics. The Department of Defense officially released the “Go Fast” video in 2020. It is available for public viewing at the Navy’s FOIA Reading Room. Key Findings AARO assesses with high confidence that the object did not move at anomalous speeds. AARO's analysis showed: • The object’s altitude was approximately 13,000 feet. • The object’s speed ranged from about 32 m/s (72 mph) to 72 m/s (161 mph) depending on its heading relative to the wind. Compensating for the wind’s contribution to the object’s speed, its approximate speed range is 2 m/s (5 mph) to 41.3 m/s (92 mph). • The object’s heading deviated as much as 32° from wind direction, though most simulations conducted during AARO’s analysis showed significantly less difference. The object did not move against the wind in any simulation.
