This is a case resolution report from the U.S. Department of Defense's All-domain Anomaly Resolution Office (AARO), dated February 6, 2025. It covers the January 2015 "Go Fast" infrared video that a Navy F/A-18F recorded off Florida. AARO worked only from the public video and found the object was at about 13,000 feet, not near the ocean surface, and moved at roughly 5 to 92 mph. The report attributes the apparent high speed to motion parallax and states with high confidence that the object showed no anomalous performance.

near the end. The bends at the end of both curves may indicate a slight change of direction but is
more likely due to residual error in the estimation of the F/A-18 flight path.
Figure 10: The position of the UAP in the x-y plane is shown over the time considered. The direction of flight is
from the upper left to the lower right.
Figure 11: The altitude of the UAP as a function of time indicates a slow rise over most of the
path with a slight descent in the last few seconds.
The beginning and end points of the path defined by Figures 8 and 9 were compared to the
results from the end-point analysis in the previous section to verify the path calculations are
consistent and that the methodology was correctly applied. The results are provided in Table II
