First flew SW to near Cataline Mtns.

Unknown flew SE with bright, white flashing light on top & flashing red light on bottom, to near Catalina Mtn, stopped, moved longitudinally back & forth a short distance, then flew north along western edge of Catalina Mtns, stopped no red flashing light but a bright flashing white light, then continued northward along edge of mtns. No green light, only white & also red flashing lights. Then flew NW and joined by a second unknown with bright flashing light on top and a flashing red light on bottom. Second unknown flew toward Catalina Mtns. First unknown started flying south toward Tangerine Road. No sound, no green light, when moving horizontally it appeared to be on a rail, i.e., no vertical change in elevation except when it appeared to drop toward the ground. Speed varied, at times very fast, at other times slowed to a stop and immediately traveled backward a short distance. Longer flights appeared to be approximately 1800 mph +/- based off time lapse and approx distances. Very smooth flight, again, appeared to be on a rail with no vertical deviation except when it dropped deliberately in elevation. Took video. Nearby houses at times blocked view of unknown. It was dark, however, when it traversed westward north of us, body of the unknown was slightly visible. From the side it appeared to be cylinder or oval shaped. At beginning 1925 hours the unknown appeared to be wrapped within a translucent sphere around it. It appeared to not have this later. Not sure if there was actually a translucent wrap or it was a reflection but it was definitely all around it. At the beginning there was an apparent commercial aircraft flying westward at a much higher elevation.
I have had a somewhat similar experience in the military at VAFB at an icbm silo. I wish to not be published on this please.
