On Saturday, September 24th, at about 7:30 pm, while sitting in our back yard in Lacey, WA, my wife and I saw something very strange in the sky. We normally see quite a bit of air craft from J.B.L.M. But what we saw yesterday was definitely unusual.Flying at what seemed to be about the same altitude as a military helicopter might fly, we saw a craft that had 2 rows of parallel lights. Each row had perhaps 4 or 5 lights. The top row was at first a bright pink. Then changed to turquoise, then red. The bottom row remained white. The brightness and size of the lights were all we saw. There was no body of a vehicle visible.Though the lights were a bit odd, the speed of the vehicle and it's ability to change or reverse directions without slowing down, and it's silence were truly unusual.Sitting in our back yard facing west, the object flew at about a 45% angle from the horizon, flying north to south, back and forth, turning sharp angles and reversing directions without slowing down.This took place just south of the Thompson Place/Tanglewilde area of Lacey WA. After flying north to south, back and forth for about 4 minutes + or – it disappeared behind the treeline to the north and was gone.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
