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.

compared to the results with no wind at all (left).
Summary
Although a complete set of data to fully solve for the location, speed, and heading of the “Go
Fast” UAP was not available at the time of this writing, AARO has high confidence that the
UAP did not exhibit anomalous or even exceptional behavior. This conclusion is based on the
results of our analysis of the range of possible scenarios. AARO notes that there is a range of
winds where the object is moving generally at windspeed and in the direction of the wind.
These foundational GEOINT techniques can be applied to a range of UAP case studies and will
be incorporated into AARO tradecraft. AARO did analyze the short section of the video from
approximately 4233 to approximately 4236 seconds where the target was acquired and the F/
A-18 flying mostly level. Results were similar to those presented here and do not change the
assessment, though the shorter section of video may result in higher uncertainty.
