My wife and myself were heading to Monterey Park after our work in Century City via route 10, to 60 to 5 freeways. Traffic was very heavy. Upon transitioning to the 5 freeway heading south I saw four bright white lights, hoovering over towards the east approximately two to three miles away. I told my wife to look at them because they were very similar to the two bright white lights I saw the previous weekend at about ten PM in the evening over the mountains on the 5 freeway just before Pyramid Lake on the opposite side of the lake, on our way back to LA from Frazier Park.After we got off the 5 freeway at Slauson, we headed east two miles past the 605 freeway and arrived at our destination. I looked up at the objects and they started to move west. The first object was moving about the speed of a helicopter however it was not a Helicopter. There was no rotor blade and no rotor sound. It passed over us, but not directly over us. It was a few degrees north. My wife heard no sound but I heard a kind of low hum wind sound, that's the best way to describe it. It was low enough and light enough outside to see it's shape vaguely, which was sort of trapazoid with lights around it. The three remaining bright white light objects started moving westward also but did not pass us because we were in route to return to West LA. We reached the 5 freeway which was like a parking lot. I saw one of the objects fly over the freeway. The bright light came from the east and passed over the freeway. I told my wife to look. As it passed over the freeway the one bright white light spread out into three bright white lights in a straight line.I witnessed one light apparently splitting into three horizontal lights. As we reached the 60 freeway transition we saw the other lights further away in the sky moving sometimes separately and sometimes lining up in the sky. As we approached Downtown I suggested we go to Little Tokyo for dinner as my wife was hungry. We got off the freeway at Alameda. Two of the objects had moved into view. One of the objects light went out and the other object moved off. I did not have my video camera with me. At first I thought the objects may be part of the police or a military exercise of some kind. If they were military aircraft they were unlike any I am familar with. I was most impressed by their ability to move slowly and aparently stop in air and their lack of noise/sound.
