Aug. 15 2014Spokane, WA 99208Friends, Wife, and I were just finishing up a BBQ around 7:45 PM Pacific Time. I Had noticed a green flash go across the horizon and disappear behind some trees, I asked if anyone else had seen it and they replied no. About 15 minutes went by and my wife asked "is that what you saw?" I looked over towards the North where i had seen the flash, and the same object was there, but this time it was hovering in one place. I told everyone to look for a camera or pull out a cell phone. My wife grabbed her phone and started filming. At first we thought it was a drone toy, however this appeared to be at the smallest 10 feet wide, then we thought helicopter until the light started moving unlike any man made craft we had ever seen, moving vertical, horizontal, and making 180 break neck turns and then descending towards the ground. It was a glowing green orb like craft with reddish orange pulsating light. All of us were stumped about the situation. Drone? I have never seen one this large and move so precise that was under control by humans. we lost sight as it descended behind a tree line.
