A diamond-shaped-looking craft with fast, flashing red lights on the bottom

It was a high-flying craft that moved in (I think) a straight line from the west horizon to the east horizon, heading toward Salt Lake City. There were non-flashing red lights on the rear of the craft and on the left and right sides of the craft. The bottom of the craft had at least four, red, flashing lights that strobed seemingly randomly and very fast. They might have been flashing in a circular sequence. The craft moved much faster than a commercial plane and there was no sound that I could hear. I was laying down next to a river, however. It was too high to really discern its shape--I could see no fuselage or wings. Due to the placement of the lights, the craft looked diamond-shaped. There was a left-right, front-back symmetry in the placement of the red lights. We were close, of course, to Dugway Proving Grounds.
