Saw Triangle shaped UFO craft with some kind of cloaking Eugene Oregon 9/25/16

I am a veteran of the military and an amateur astronomer so I am pretty good at aircraft identifications and where lights should be in the sky. Last night, 09/25/2016, at approximately 20:15 I saw what looked to be a triangle shaped UFO craft over the city of Eugene, Oregon.

I had just stepped out on my balcony for a smoke and sat down in my chair facing East overlooking most of NE Eugene and N Springfield. Looking in the sky above and well beyond the neighbor's house at the sight line of the power lines I saw 3 orange lights equidistant apart and in a triangle. It occurred to me that there shouldn't be bright stars in the sky in that area that time of night and time of year so I looked closer.

As I looked closer at the UFO, I saw the bottom most of the lights moving and then I thought to myself: that makes sense it is commercial aviation. So I looked back at the other 2 lights and saw they were moving together too and that it was one triangle shaped craft rotating on its center axis. All the while I noticed the bright orange lights were shining through what looked like heat shimmer coming off the desert floor.

Very much like a scene from the movie, "Predator," the "cloaking" around it wavered for just a brief second and when it did I saw a large triangle shaped craft with smooth sides and a smooth metallic bottom with a smaller circular abutment in the center with a light bluish glow. The UFO stopped rotating and it looked like a harrier jet pulling up its nose on a vertical takeoff and then it disappeared. It did leave but as it was leaving the "cloaking" kicked back in and it disappeared from sight.

Like something out of the X files 2 helicopters showed up within 30 seconds of the UFO disappearing. Eugene is a small city and helicopters are fairly rare here with just a couple of overflights a day but these stayed on station for the better part of an hour circling over the Eugene/Springfield area. nuforc UFO Sightings report
