Low flying, noisy low pitch type sound, large rectangular blue light with two red same-sized lights right behind.Cloudy and overcast night, thing flew below clouds, large rectangular blue lights very intense and large, and then two red lights set side by side right behind the blue light, blue light blinking, was in front, travelling south by southeast towards mountains. Could not get a sense of the size. Very loud and weird noise, repetitive drumming-type sound, sounded like the large balloon tires on the lime spreaders. Low pitch drumming type sound, could be heard inside the house.
