Glowing White craft with Blue light on bottom observing Fireworks.
Local municipality fireworks were going off 200 yards in front of my house. Was not interested so went outside on back porch to smoke. Looked up and spotted white oval craft with bright blue underbelly several hundred feet above me in sky. It was slowly pacing back and forth as though it was watching fireworks. Went inside to get my camera and as I held it up toward craft to take a photo the blue underbelly light turned red and then craft zoomed westward very quickly. Did not get photo, it was as if it saw me and did not want it's photo taken. Did not see craft again. Sighting lasted 3 - 4 minutes.
