Two stationery craft

We noticed two lights in the western sky from Brandon, so these may have been over the northern part of Sioux Falls. The two lights appeared to be coming from the bottom of two craft that looked to the naked eye like they were boomerang shaped, but zooming in on the camera image, the shapes appear to be more like crosses - very thick (height-wise) crosses that would be several times taller than one would expect a plane to be. We checked back on them several times over the course of about half an hour and they were not moving. I stepped outside to see if I could hear rotors, but could not. The last time we checked on them, they appeared further away, but were in the same position in the sky and relative to each other.
