Looked like a bright twinkling star. Eraditic and abrupt change in speed with sharp right angle turns like the letter ‘L’.

Sometimes it would just stay put. High altitude. 3 times I saw it accelerate forward very fast, abrubtly stop, the fast again. I held my thumb out at full arms length and I would say that these short little streaks occurred within the same width of my thumb in related distance. From my vantage point, it appeared to be directly above a military site known as the Yakima Training Center. A witness friend who lives in Naches went out to watch it. That is about 18 miles NW of Yakima. He said another one was directly SSE over Yakima, probably over (Hanford Nuclear Reservation). My son was watching that one while I was watching the other one, NNE of my point. Mounted video camera with telephoto lens on tripod to stabalize clear video! Centered on screen. Camera didn’t move but clearly the UFO did.
