Below an interesting UFO sighting recorded from the ISS live feed on September 12, 2015
Streetcap1 has recorded the movement of the UFO.
Who knows what these are? I am always reluctant to call them alien as they could be part of a secret space project or tests in the upper atmosphere.
About the first UFO who emerges above the clouds, it's hard to tell if that was one segmented object or two; there seemed to be some separation between the two. Whatever it was, it seemed to dissipate as it gained altitude, unlike a solid object or objects.
