Unlike the AF crash i suspect this airbus hit the sea with some forward speed, cartwheeled and came apart.
I further suspect that this was a weather induced loss of control and at some stage an attempt at recovery was made, but the vertical rate of descent and space between cloud base and hard deck was insufficient
I very much doubt the weather was directly responsible the break up, but if they ended up in a viscous updraft and pitched down and cut the thrust it would be very easy to loose it and recovery in cloud with no visual reference, much turbulence and all manner of warnings going off......there but for the grace of god
