The object moves from the top right to the lower left of the screen. There's no plume of exhaust, no wings, no propellers. Just a speedy little egg out for a jaunt above the ocean. At the time, no one in DoD or the IC could explain it. After several years of analysis, however, later researchers would claim that the object was going much slower than previously thought. This effect is called a parallax. I still don't agree with this assessment, since the pilots who witnessed the object flying marveled at its speed.
