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.

UNCLASSIFIED 8 UNCLASSIFIED Figure 4: The three axes defined relative to an air platform in FMV analysis. Longitudinal is the +x, Transverse is the +y, and Vertical is the +z (pointing down). This coordinate system was applied to the F/A-18 as depicted in Figure 3. Because the aircraft altitude was constant over the duration of flight, its path is level and confined to the x-y plane (z = 0). Figure 5: The top-down view coordinate system defined with the position of the F/A-18 at the origin with coordinates [0,0,0]. The aircraft is moving in the +x direction. With the position of the F/A-18 defined at t1, the location of the UAP relative to this position was calculated. This calculation was done by defining a line-of-sight (LOS) or “pointing” vector and then rotating this vector around the axes by the sensor azimuth and elevation angles given in Table I in order to point to the location of the UAP. The angle of rotation about the x-axis is the aircraft roll and is denoted by α; the angle of rotation about the y-axis is the “up and down” motion due to the aircraft pitch or sensor pointing08Page determined to be Unclassified Reviewed by Chief of Staff, AARO IAW FY24 NDAA, Section 1841(a)(1)(C) Date: 2/14/2025
