mm43 and swordfish41,
Is there a possibility that Turbine D is right, and that it is the tail section (by which I think he is referring to the aft fuselage)?
Would the debris field alignment (approximately 070/250) necessarily be roughly indicative of the heading at sea-level impact, despite currents on the way down? If the curved piece in the north-east was the aft fuselage, would that suggest the Hdg 250 rather than the 070?
swordfish41,
Do you think the engines may be present in this pictured debris field? Could the laterally-lying pieces extending northwards include a wing box?
