This is the first picture I can see something without a good measure of wishful thinking / imagination - mind you, I'm not saying the things are not what we think they might be, I'm just not sure we're looking at shadows...
I'm just wondering about the enhancement - was that done using some objective rules, or by hand with the specific intent of highliting the wheel?
Anyway, what would be interesting right now is to have a composite made of the video, showing the entire area covered by the ROV, indicating what parts might have been identified and their exact location, to see if there is some sort of logical arrangement to them. Surely if there are wingsections and control surfaces visible, then it is not unreasonable to have the other various bits and pieces still in a configuration that corresponds to the shape of the Electra...
