OK then why isn’t part of the door visible & sticking out of the water; the lower edge of the door should be up above the roof line, as seen in the puentes vid ..

You need to see an eye doctor. Seriously.

Check again. The door is up and above the roof line. See the shadow on the fuselage? It’s from the door in the up position. The photo was taken edge-on to the door so only a line is visible. But the shadow confirms it.

Perspective and camera angle, also, the plane is sinking Look again, it’s quite clear..

The door is open on the second photo, you can see the shadow of the door on the roof of the plane.

(sorry for the size of this pic)

The dark streak being pointed at by the arrow is the bottom edge of the open door.

The shadow says the upper part of the door is there.

Maybe it was open and then closed?
Simple answers sometimes are right. Waves, someone crawled over it. etc...?

The door is visible. You are just not recognizing it as the door. You are looking at the supposedly missing aft window and mistaking it for the passenger door. The passenger door has an upper and a lower part. The lower part is dropped don to provide a passenger stairway. This lower door part is submerged in the seawater in the Lang photograph. The upper part of the door is raised in the Lang photograph. Because the angle of view in the Lang photograph is edge on to this door, many people are mistaking the door as a dark shadow. In actual fact, that dark shadow is the door seen along its edge. If you look carefully, you can see this upraised door is casting a shadow along the top of the aircraft. In the center of that shadow is a rectangle or parallelogram of light which resulted from the light passing through the window in that upraised door.

What some people are mistaking as the upper door in a nearly closed position is actually the aft window they mistakenly claim is missing.
