Lying in hammock at 6:25pm. Strange looking objet flying from southwest to southeast in bright sunshine. Many jets fly over my house from the east & the west on the way to Sea-Tac. I immediately knew this was not plane. It was a gold triangle with a black horizontal trailing edge. It was hollow in the center & had 6 pointy shafts on the leading edge. This thing flew upright in a straight sideways line then everything few seconds it would spin. It was brilliant gold color. The only other colors was the black horizontal trailing edge. The craft had detailed shape. I was able to watch with binoculars for 15 seconds until I lost it behind the trees. I was in awe. This was my first sighting, & it was mind blowing. It was a beautiful object.
