The apparent extreme speed in the 2015 'Go Fast' video was largely a parallax illusion caused by the observing aircraft's own rapid motion (about 430 mph), not by the tracked object's actual speed.
some or most of the motion that we observe, the apparent motion of the object, is in fact due to the rapid motion of the sensing platform, which is about 430 miles per hour in this case
Our check Confirmed closely: physicist Josh Semeter (Boston University, Director for Space Physics) presented a trigonometric/telemetry reconstruction of the Go Fast video at a NASA UAP panel, placing the object at about 13,000 feet altitude and roughly 390 meters of travel over 22 seconds (~40 mph), noting this matches typical wind speed at that altitude and that apparent extreme speed was largely a parallax effect from the aircraft's own ~435 mph groundspeed. This independently corroborates AARO's own 2023 case-resolution finding of non-anomalous speed (roughly 5-92 mph depending on assumptions).

A quantitative reconstruction of the 2015 'Go Fast' Navy video, using onscreen elevation, azimuth, range, altitude and airspeed telemetry, placed the object at roughly 13,000 feet altitude, moving about 390 meters in 22 seconds (roughly 40 mph), consistent with wind speed at that altitude - not the extreme speed suggested by the video's nickname.
this object moved about 390 meters in 22 seconds, and that corresponds to a velocity of just 40 miles per hour, and so that's a velocity is consistent with wind speeds at 13,000 feet
