UFO Sighting in Santa Fe Springs, California on November 8th 2015 – 7+ cluster of white light/reflective objects moving very quickly, many made quick banks, up/down

1150am on 11/08/2015. Perfectly clear and sunny day in all directions. I saw a cluster of 7+ white/reflective obects heading from South to North. The objects were twinkling somewhat, some blinking. At first I thought it was debris caught high up in a air current. However, the objects were displaying up/down, angular/banking movents. Their moments were independent from one another. I then thought they were seagulls. By this time, I became very curious, and walked further out my back yard, to watch them straight on as they moved away from. I focused on a few and saw that they were making steep banks from left to right, and some were just punching straight ahead moving up/down, but always as a group. It was then I realized that they were not seagulls, because they moved to fast overhead, and the banks they were making moved to quickly across the sky to be birds. I used telephone wires as a reference point, so I was able to observe their movements very well. Most of them simply disappeared as they headed north. If they were regular objects I would have been able to watch them longer, and get smaller and smaller as they headed north. The last one I saw, before it disappeared, I framed up with a telephone pole and a wire, as an axis reference. It moved up and down, while moving away, casting a reflective/white light pulsation. It then simply disappeared. All the objects disappeared, rather than moving ahead with their the average speed I witnessed. These objects were crafts. Not one doubt in my mind. As a personal side note, I am educated (law school) and a professional. I rate my eyesight and observational skills as excellent. I am always observing my surroundings and can easily discern/identify/deduce what I observe. Thank you for your time. --Adam Segovia
