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.

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.08Page determined to be Unclassified
