Comparing the photo of the fin/rudder and the video taken in the rear door area suggests that at least 2 large sections have been found. Concerning the video, it does rather look as if part of the lower shell may be missing in the area under the main cabin, although the diver could be standing on it, the cabin floor being absent. Interesting to note that the overhead bins stop just ahead of a large hole in the skin, which appears not to be the door. Isn't that where a lavatory would normally be?
