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.

Because the frame-by-frame method estimates the parameters to a better precision than just integers and more accurately assigns the time to each value, it is presumed that this method is more accurate8. Table II: Comparison of results from the two-point and Continuous Path analysis. Incorporating Prevailing Winds To this point, analysis has assumed no effect from the speed and direction of the winds aloft on the flight path of the F/A-18. The speed on the sensor display in Mach number represents the relative air speed of the aircraft and does not consider the ambient wind velocity. With a methodology in place to calculate the UAP locations, the possible effects of the winds at altitude were explored. This is done by adding the speed and direction of the wind to the speed and direction of the F/A-18 to obtain a new flight path, then determining the UAP flight path as described in the previous sections. Wind Speed and Direction No information on atmospheric conditions was provided with the UAP report or video, only a time and general location. Therefore, the historical data for wind speed, direction, and altitude were sourced from a historical database (ref 9]. The data for the appropriate date and location were found and were within 15-20 minutes of the time reported with the “Go Fast” event. The windspeed and direction are plotted in Figure 10. At 25,000 ft (7,620 m), the windspeed was approximately 101 kts (52.0 m/s) at a heading of 255°, from primarily the West-South-West and blowing toward the East-North-East. At 13,000 ft (3,692 m), the wind speed was 60 kts (30.9 m/s) at a heading of 265°, primarily from the west9. 8 All analytic results are relative to the accuracy of the F/A 18’s estimated flight path. It is not possible to state the accuracy for certain without knowing the exact path of the UAP. 9 Going forward, we will use the metric system. Values here are in kts and ft to represent the data as taken from the source.Method Starting Point Ending Point Distance Speed Continuous Path [4284, -4889, 3601] m [4500, -4953, 3592] m 226 m 17.4 m/s (38.9 mph) First / Last Frame [4251, -4890, 3591] m [4510, -4941, 3612] m 265 m 20.4 m/s (45.6 mph)
