AARO GoFast Case Resolution and Methodology

All-domain Anomaly Resolution Office · 2025-02-06 · 26 pages · text from the file's own layer

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.

Figure 13: The path of the F/A-18 with no wind considered is in black. The other lines show the flight paths with a
head, tail, and two cross winds applied.
Estimated Flight Path of the UAP
With the flight path of the F/A-18 for the four wind conditions calculated, the resulting paths of
the UAP were found using the same method as in the case without wind. The four resulting
paths are plotted in Figure 12. Note than in each case, the UAP is headed in the same general
direction as the wind at the altitude of the F/A -18 (7,620 m), which is comparable to the wind
direction at the altitude of the UAP (a 10° difference as shown in Figure 10).
