The water is reportedly only about 100 feet / 30 metres deep.
The currents are reportedly only up to about 6 knots.
If one assumed that the aircraft pancaked, or even broke up attempting to ditch, you would expect that the remainder of the aircraft, particularly all the concentrated mass components, ie, the dense and heavy bits, like engines, apu, mlgs, nlg, and if they separated from their mounting trays, the cvr, fdr etc, and the other larger major components like ths, outboard wing panels, and centre section, would be, indeed must be, immediately proximate, regardless of currents.
So far, that does not seem to be the case.
There is no evidence, at this stage, of any other major component wreckage, anywhere, let alone anywhere near the location of the tail.
It has been reported that a suspected pinger is over a mile away.
The reported condition of the recovered bodys (at this stage less than one third) suggests relatively low "g" conditions.
The leaked mode "s" data showed high rod at much below cruise level.
Taken together therefore, these observations suggest strongly to me, the high probability of an in flight breakup, not a whole aircraft experiencing surface induced structural disruption.
My viewing of the recovered upper empenage and fin, and lower rudder, suggests to me, that the ths, and it's mounting structure (including apu mounting structure and apu) most likely separated from the upper empenage by downward bending with pitch down torsion.
If that is the case, it would have taken tremendous downward ths loading of the support structure to do that, which suggests to me, probable breakup during pull-up, attempting recovery from a significantly pitch down attitude, at high speed (high dynamic pressure), probably at a relatively low altitude, ie, between FL200 - FL100.
Under such conditions, if the ths separated first, with the aircraft otherwise still "whole at that instant", the remainder of the aircraft would immediately, and violently, "tumble in the pitch down direction", with high angular velocity. The weakened empenage would "immediately" tear off, and the remaining fuselage aft of the wing, and the fuselage forward of the wing, would then both rapidly separate from the wingbox, probably before the pitch axis had even passed through the vertical. In the same timeframe, the pylons would fail, the engines would separate, and the outboard wing sections would fail in downward bending and torsion overload, and separate, probably at or just outboard of the pylons.
The schredded wreckage would then descend.
If that be the case, the greater the altitude of the breakup, the greater the dimensions of the resulting debris field.
The foreward section of the fuselage, and the remaing aft section of the fuselage, may have remained relatively intact, and may still contain most of the occupants.
