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 22 UNCLASSIFIED Results A summary of the results for the distance travelled, intrinsic speed, and relative heading with respect to wind direction are provided in Table III for the four directional cases considered. The wind direction at 3,692 m, the altitude of the UAP, was calculated by adding 10° to the direction at 7,620 m, the altitude of the F/A-18 (see Figure 10). The wind directions in the Table III are again with respect to the position of the F/A-18 at t1. Table III: UAP speed and heading with windspeed considered. Visualizations To visualize the F/A-18 flight paths shown in Figure 11 and the directions with respect to the winds at altitude, they were placed on a map. Instead of relative to the F/A-18, the wind directions will now be defined assuming the wind was blowing from 255° as reported. Figure 15 displays the four flight directions on a map with the F/A-18 placed in an arbitrary location off the east coast of Florida. While the directions and relative lengths of the paths are accurate, the exact locations and path lengths are for visualization purposes only. Figure 17: The possible directions of flight of the F/A-18 based on the assumed wind at 7,620 m from a direction of 255°. The relative lengths of the paths are representative of the distance flown. To visualize the UAP speed and heading they were also placed on the map off the coast of Florida. Figures 16-19 display the UAP position relative to the F/A-18 with two arrows: theWind Heading @ 7,620 m UAP Distance Travelled (m) Wind Speed @ 3,962 m (m/s) Wind Heading @ 3,962 m UAP Heading Heading Difference from Wind UAP Intrinsic Speed (m/s) 0° (Tailwind) 928.8 30.9 10° -2.3° -12.3° 41.25 90° (from Left) 687 30.9 100° 68.4° -31.6° 26.50 180° (Headwind) 425.7 30.9 190° 185° -5.0° 2.00 270° (from Right) 756.3 30.9 280° 289.5° +9.5° 27.70 Wind: 52 m/s (101 kts) @ 7,620 m (25,000 ft)
