Domino-shaped UFO appears over San Diego, California

On December 16, 2014, a brother and his sister were in San Diego, California. Man decided to take some photos of the landscape. He noticed, on images, a mysterious and incredible domino-shaped UFO!

Witness statement:

I was in San Pedro California with my sister, as I was taking pictures of the beautiful view I had I noticed something was off in the sky. So I proceeded to take more pictures and I realized there was a domino effect of light in the sky. At first I thought maybe something was reflecting off the floor but there couldn't have been because beneath the object was the ocean. When i kept looking at the object it started moving NW within a matter of seconds it literally disappeared into the clouds. I was more excited and amazed more than anything because I have never seen anything like it before. The object just disappeared into the clouds.
