Littering and____

5 other people and myself saw this near Battleground, WA on Sunday August 2nd at about 2145. It was travelling west to east. People were trying like mad to get their phones out to record it but it was way too fast and probably too dim. I track the ISS and satellites as does everyone in our group. We were all, for lack of a better expression, blown away by what we witnessed. My sat app showed nothing. I was able to look through my binoculars at it but all I could see was a yellow dot. I watched it as it fell over the horizon. We kept our eyes in the sky for the next couple of hours but did not see it again. It was really moving. Straight and fast. It was really cool to see it. It seemed like less than 2 minutes from horizon to horizon. My only other thought was it was a weather balloon riding the jet stream. But i don't think they could travel that fast. All the nay sayers can believe and say what they want. I am here to tell you this was no ordinary satellite. New spy tech?
