I was sent an article showing a pic tweeted by Scott Kelly recently and in it the article says "some UFO bloggers" see what appears to be a cigar shaped UFO. If you look closely though there's something hidden a bit in the darkness. Of course I had to explore it uh, reminds me a bit of a Klingon Bird-Of-Prey (raise shields!). Looked through more of Scott's pics and you can definitely see some image/glare artifact funkiness in some of them so maybe this giant thing is nothing more than that. One commenter believes it's just a reflection of ISS itself. If so that probably answers the cigar shaped UFO question also.
