Drove up to Publix on Atlanta Highway in Montgomery, AL to see 5 yellow lights in a disc pattern moving across the sky just behind the store to the Northwest. It was making a wide circle over the residential area behind the store, before the lights faded and a new red blinking light appeared, just like a helicopter or commercial airplane. The light flew away and then returned, appearing to become larger as the 5 lights slowly came on again. When the yellow lights came on it was clear that this thing was very large, probably the size of a large commercial airliner. It did this a few more times before turning on its blinking red light and moving away to the west. Unlike any helicopter I've ever seen or heard of, though its movements and blinking red lights were just like a helicopters.
