One comment, one note, two images.
I assume the turbulence penetration speed for an A-330 is not mach 0.82.
I re-found the lat & long for the VS recovery point on June 7 (unofficial source): 3.41N, 30.42W. The first body(ies) recovered were June 6 at 3.34'05"N 30.27'18"W. There is a progressive northward recovery of bodies and wreckage over time, although recoveries in the latter days of the search are significantly more north and west of Tasil. (I assume the searching vessels were on courses from south to north as they recovered. If they had been on a north to south course, they would have intercepted the drifting wreckage sooner.)
This is the French bathymetric profile. No coordinates are given, but if the grid is the same as the chart prepared for the bottom sediment, it is roughly centered on 3.0N and from 30.0 to 30.65W
Unfortunately, the western sectors of the search area are the more mountainous and rugged, and likely to impede locating and/or retrieving the FDR and CDR.
