U.F.O. skeptics and experts in optics have long said many of the videos and sightings by naval aviators represent optical illusions that have made ordinary objects — weather balloons, commercial drones — appear to move faster than possible.
Military officials have largely come to the same conclusion.
Besides the images of the green triangles, the other recordings released by the Pentagon have not been categorized as surveillance incidents, at least so far. But Pentagon officials do not believe that any of them represent aliens, either.
One of the videos, referred to as GoFast, appears to show an object moving at immense speed. But an analysis by the military says that is an illusion created by the angle of observation against water. According to Pentagon calculations, the object is moving only about 30 miles per hour.
Another video, known as Gimbal, shows an object that appears to be turning or spinning. Military officials now believe that is the optics of the classified image sensor, designed to help target weapons, make the object appear like it is moving in a strange way.
Military analysts remain puzzled by the third video, known as Flir1. The object captured in the 2004 video appears to hover over the water, jump erratically, then peel away. Military officials say that event is more difficult to explain, but officials who have studied it are convinced it is not a piece of alien technology.
So it seems like the upcoming report, or at least the discussions with officials, largely confirm what we have been saying here for a few years.
