The All-domain Anomaly Resolution Office of the U.S. Department of Defense issued this case resolution on the "Go Fast" video on February 6, 2025. It covers a January 2015 FLIR recording made by a U.S. Navy F/A-18F off Florida's eastern coast. From the public 34-second video, AARO puts the object at about 13,000 feet, moving at 5 to 92 mph relative to the wind. It attributes the apparent high speed to motion parallax and has high confidence the object showed no anomalous performance.
UNCLASSIFIED 1 UNCLASSIFIED All-domain Anomaly Resolution Office U.S. Department of Defense Case: “Go Fast” Case Resolution | February 6, 2025 Case Essentials Location: Eastern coast of Florida Date: January 2015 Object Altitude (reported): Near ocean’s surface Object Altitude (assessed): 13,000 feet Object Speed (reported): Appeared to move at high speeds Object Speed (assessed): 5 mph - 92 mph Object Shape (reported): Round Object Shape (assessed): Spherical or oblate ellipsoid Reporter: U.S. Navy Sensor: Forward Looking Infrared Reported Behavior: Moved at high speeds near the ocean’s surface Assessed Behavior: An object moving between 5 and 92 mph at approximately 13,000 feet Summary of Findings: High confidence the object did not demonstrate anomalous performance characteristics 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.
