There is more than one incident. In one incident (2004 Nimitz FLIR1, west coast), the object is static and then initiates non-newtonian acceleration. In the next (GIMBAL, undated, east coast), the same behavior of static hovering with non-newtonian motion. In another, your example (2015 GOFAST, west coast) a slightly different elongated object is cruising at Mach 0.5 at low altitude, close to the water.
