Oh, c'mon everyone! Pull your heads out of the sand!
It's an alien invasion scout ship. It's probably sending mind control rays at this very moment to convince you that this post is pure nonsense! And, the weaker minded ones will succumb to its insidious mind control attacks!

SOMETHING is going on. What? Who knows. There's always some way to explain away anything that doesn't fit into the mainstream narrative, and that will always trump any kind of questioning or inquisitiveness, because only "conspiracy theorists" ever question anything, and as we "know", all conspiracies are false.
In the meantime, it sure would be interesting to know what that thing is. It's not like there are a lot of possibilities when you get up to those kinds of altitudes.
As for NASA releasing the picture, I kind of wonder there... Why would you need to "declassify" a photo from orbit? Is truth something that requires sanitation?
