The HD video of the wreckage on TIGHAR's youtube channel has some pretty interesting shapes/contours when viewed at 1080p.
Perhaps better seen as a movie than a single screen capture, in order to understand the shape and geometry of a so-called "object."
I won't suggest what a particular object is, but the shapes are rather interesting to note when following it in the video.
(These images are bit big, and objects appear very distinct from its surroundings, at least on a photo editing monitor)

A careful look
could make one think there is some sort of text there on black object behind "plant," when watching the video(?). Note the cable to its right. (
