Something made me look out my window around 5:50 pm. and I looked directly at a triangle shaped object moving very slowly across the sky. it had 3 blinking pulsating red lights with a yellow light in the middle of the craft. I could see the outline of the craft even though it was dark outside. I got my camera & keys & headed to the car to follow it & take a picture but in the few seconds it took to get outside, it was gone. Shortly after that I heard the sound of jet engines , like military planes use.
