I think the intermediate report reduced that to two (or 3 if you count the inital 180).
Quite different from the initial "zig zag to avoid radar" information...
Has it ever been known for a T7 to lose wing parts like a flaperon?
When they chop them up by excavators on so called third world "recycling" companies, such items come off. As the composite can not be recycled, they get piled up on some dump. Add a typhoon or a hurricane to that scenario, and one may be floating around.
Probably not very likely, but more likely than being hijacked by alliens...
And that item looks neither like chopped off, nor like intentionally removed.
More analysis will tell, at least we have
something now to do real technical work.
