this picture of the early entry phase into a (fatal) spin for example. In the following second the aircraft will be in an almost vertical dive still acellerating the rotational speed before entering a stable spin after somr 5-10 seconds. If you run out of altitude at that moment, the result looks like in
this picture. Which matches the Junkers wreakage quite well.
The video of the seaplane crash into the Swan River last year is worth looking at if not seen before........
