This image was put in connection with the film of the -92 spotting.
What it is is hard to tell. What is sure is that it's not a bird, bat, gigant bat / flying fox.
The type of trees are the same in the film as in this image. I think they closely linked in time and place.
I don't know if it's a still from a film or a photo, I'm quite sure it's a frame from a film.
