Weird UFO flying against the wind over Westminster

On May 10, 2018, a witness observed a strange object moving south to north against the wind over Westminster, Colorado.

Witness statement:

I observed what I can best describe as a diamond shaped black object that for visual reference looked like a inflated black trash bag. The object appear to be approximately 2000 feet above the ground maybe less. The object was traveling from the south to the north against the wind pattern. I observe the object through a pair of binoculars and took video with an iPhone through the binoculars. The object was traveling south to north over Standley lake and continuing on a pattern that would take it over Rocky Mountain metropolitan airport. The object appeared to have a silver object hanging below the main body. The object was black in color but had a shiny surface. The duration of watching this subject was approximately 15 minutes. I estimate the size of the object to be approximately that of a single engine Cessna aircraft may be larger. There was zero noise and again it floated in a generally stable south to north direction and the best I could tell did not change in altitude or course.

I do have video and screen capture pictures that show relatively good detail of the object. The video is shaky because I was taking it through a pair of binoculars using an iPhone. I did call the FAA tower at Rocky Mount Metropolitan Airport and reported the siding by leaving a message.
