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 8: The sensor elevation “change frame” data points are plotted vs frame time. The dotted line was fit to the
points to estimate the elevation for all frames in the time interval.
Figure 9: The range to target “change frame” data points are plotted vs frame time. The dotted line was fit to the
points to estimate the range for all frames in the time interval.
With values estimated for all frames and times, the vector rotation and point translation
methodology described in the previous section were applied to find the UAP’s three-dimensional
flight path. The resulting path through the x-y plane is plotted in Figure 8. The UAP’s direction
of travel is a relatively straight path from the top left to the bottom right. The altitude profile is
provided in Figure 9 and shows the UAP rising about 10 m (30 ft) with a slow, curving descent08Page determined to be Unclassified
