Wooo! Horror! I like it! And now I'm thinking about it...
Ok, so I'm on the fence here if I should interpret this as the old school Twilight Zone 'Nightmare at 20,000 Feet' face in the window as a ghost or creepy alien...or...is it the physical disembodied head of a victim from the crash, just kind of laying there?
Well, horror is in the eyes of the beholder, as they say. Okay, maybe they don’t actually say that, but the point is you get to decide. I was a conduit for the words that joined the image here in this post, and lay no claim to their interpretation. (But for the record, a theory combining several ideas you’ve put forth — crash, victim, ghost — seems most plausible to me.)
