Still missing - update 10
Freezing the start-thread gave me time to catch up on videos and photos. From what i have found till now, major sections still missing (on photos in the public domain):
A. Vertical tail box structure,
B. Rudder,
C. Most of the Aft cargo hold/cabin ... Which includes doors, hatches, floorgrid, panels ... So about 10-15 meters.
Non-technical official and press reports can be quite inaccurate. If i therefore take the word "tail" in its widest possible meaning... And take only the most probable options for a bomb location ... I get 5 different locations/spaces. Some of these have upto 5-6 possible points. For a total of at least 15 probable points. With two unexpected ones.
In a number of these points you could roughly match what you see with a relatively small explosion, but in these instances it is then quite difficult to match it with the other 'evidence' like CVR remarks, AP1 still ON, and aft cabin fire respectively.
