The interesting thing about this video is that an airplane flies through the triangle formation which allows you to see how large each light is at the three points in the triangle. This rules out the most common suspect, "Chinese Lanterns".
A triangle formation of bright white steady lights appear in the skies over Oakland, the objects appear to be in direct path of on comming passenger jet which surely the pilots would have witnessed them and maybe reported them. This footage is interesting and worth a watch. It happen over on7th street at the? port of oakland.
