I’m not saying it actually is one, just that the shape, trajectory and suggestions of aerodynamics make it look rather so. There’s even what looks like a shockwave ahead of the object evident in the edge of the cloudbank.
Not sure what you’re using as reference for scale, either. It could be anything from the size of a VW Beetle on up to Space Shuttle in size, perhaps even larger than that.
I’m using the general appearance of the clouds for scale, along with an assumption of their height, so just a cloud-watcher’s feeling.
The “contrails” are very “lazy” and appear to be trailing an object going 10’s of mile per hour. An Apollo capsule on reentry would have traversed this scene in a few seconds ... at 100,000 feet! At the apparent altitude of this shape, or object, it would have its chutes open. I would have to guess that this is a purely meteorological phenomenon. Some kind of vortex at altitude? Who knows!
