I was walking towards my house it was towards the end of dusk when i noticed an bright white light moving across the sky at a high altitude, heading northeast climbing from about 60° climbing towards 70°. i thought it was the internatinal space station until the lights went from pulsating to blinking as it broke from the path before a brief absence before the object flickered coming back into view briefly down 55° heading southeast as it appeared to rapidly accelerate out of sight. the overall appearance of the light appeared almost as if emitted from the objects drive and the various phases appeared to correlate with the change of speed and direction. i live beneath the flight path of mountain home airforce base and have seen every sort of aircraft they fly including project aurora and this wasn't like anything i've seen.
