I was watching fireworks on July 4, 2012, from about 1/2 mile away when three orange orbs appeared from within the fireworks and kept travelling in my direction and overhead. I looked at one with binoculars and could see it clearly with the setting sun in front of it and saw that it was a black sphere of consideraqble size. I would guess about 50-100 ft. wide. There was absolutely no sound as they passed overhead, no headlights, no strobe, nothing but the oraqnge glow seeming to be on the bottom of the sphere. One came out first by itself, that is the one I saw with the binoculars, they other two came out a few minutes later, travelling in the same northerly direction. The orange glow on the last two seemed to go on and off infrequently, then they dissappeared all together. They rose to a much higher altitude than the first one.
