So far I have not accurate information about the horizontal velocity of the AF447 on impact .. do you have one ?
Sorry, nothing I can easily pass on. Only a somewhat calibrated eyeball.
What I see in the AF447 wreckage that has been pictured is a strong vertical component of damage, a weaker horizontal component of damage, and a relatively short/low energy (less than 160 Knot total velocity) churn time (but my eye has been calibrated by just a few accidents involving smaller aircraft).
