The All-domain Anomaly Resolution Office of the U.S. Department of Defense issued this case resolution on February 6, 2025, with a technical appendix, on the "Go Fast" video recorded by a U.S. Navy F/A-18F FLIR sensor off Florida in January 2015. Working from the public 34-second video, AARO puts the object at about 13,000 feet, moving roughly 5 to 92 mph once wind is accounted for. It concludes with high confidence that the object showed no anomalous performance and that its apparent speed came from motion parallax.
UNCLASSIFIED 24 UNCLASSIFIED Figure 20: The direction of flight and speed of the UAP in the case of the F/A-18 flying with a tailwind. The UAP is going over twice as fast as the wind in somewhat the same direction. Figure 21: The direction of flight and speed of the UAP in the case of a crosswind from the right of the F/A-18. The UAP is going much faster than the wind but in nearly the same direction. Conclusions The methodology used to analyze the “Go Fast” event was derived from standard FMV analysis and successfully applied to data manually extracted from a publicly available .wmv video of the FLIR sensor display of an F/A-18. Accuracy of the results were limited by the precision and accuracy of the data and assumptions made regarding the flight parameters of the F/A-18 (e.g., the curved flight path). Calculations of the UAP’s exact position and heading were not possible given that the true track data in latitude and longitude of the F/A-18 were not provided nor were the atmospheric conditions. Thus, the estimations of the speed and relative direction of travel are used to bound results under a range of conditions to constrain the possible characteristics and performance of the UAP.
