For the U-turn hypothesis and the infered crash area, is it possible that an airliner (at the assumed flight point, airspeed and altitude) bank with such a short radius curve ? (as plotted on the map)
Just remembering the order for the recovery of the debris and bodies: the first piece collected (on june 6) was the crew rest cabin remain (where is the mobile crew rest deck in the A330 ?), less than 2 days later, the vertical stabilizer was found, and latter other groups of bodies/debris (the whole with a large dispersion)
Doesn't it suggest that these people and pieces were first lost in flight after the last ACARS, that the VS was lost and the rear part of the A330 fuselage may have been severely damaged in mid air ? (In this case, the airplane didn't try to make a U-turn but simply tried to control its attitude and its altitude)
Apart from a stall, how can an airliner break up in mid-air in cunjunction with all the reported avionics faults ? (a cumulonimbus breaking a plane does not need the ACARS faults: would-it explain them ? whereas the stall possibility can stem from these).
Why isn't it interesting to consider the early leakage from the LAV L54 (which had already problems on the 10th of May) toward the rear of the plane: isn't the BEA right when it suggests that combined to the very low temperatures encountered may have frozen a part of the composite structures, weakening them, making them more prone to a structural failure under heavy stress ? What is the volume of the fluids that may have leaked ? (<100 l, 500 l ?), from which part of the wasted fluids circuit, and in which areas would it flow in more than 3 hours ?
Can't we assume that the A330 tail and other control surfaces were under heavy constraints (no longuer protected by the normal law) while trying to recover from assumed situation of emergency ? (possibly creating a huge torgue of the rear part of the fuselage)
Is an airliner without its VS still in control in a turbulent atmosphere ? would it be in ideal flight conditions ?
To conclude, can't there be a large initial dispersion that was increased by the several days drift ? The A330 airspeed gradually decreasing between 02:10 and 02:14, then a final trajectory initiated by a stall with a right bank, loss of VS/rear part of the fuselage, gradually loosing passengers and pieces, ending 10-20 NM south east of TASIL. Then a few days NW drift of this initial distribution)

PS) my apologies if these questions were already answered.
