Many reports of this type of  UFO Craft were widely reported during the 1980's especially in and around the Hudson Valley of New York State.

The return of this type of UFO was reported on Oct. 25, 2020 report reads as follows. Vehicle was traveling west at maybe a thousand feet. It was boomerang shaped with a dark black surface.

UFO Sighting had white lights evenly spaced along the outer edge of the vehicle. It was not shaped like a wing. It did not look aerodynamic like a wing. the shape was the same thickness all the way around the vehicle. It was moving quickly but not supersonic. All the lights were white in color and were spaced at exact intervals along outside edge. I could not make out any features on the black surface. It was very low in altitude and made absolutely no noise at all.
