takata, with respect to drift, and possible point of impact, and whether there was a controlled glide or not.
First image is of the search grids for June 1 as flown by the Brazilian Air Force.
Second and third images charts the recoveries of bodies and wreckage on June 6. Top image numbers the wreckage items, but gives no coordinates. Bottom image gives no item numbers, but gives coordinates. I know of only one item that has so far been described as being recovered this day from this area, and that was a seat cushion with a serial number. From an eyeball glance, I believe that if the bodies and wreckage had been where they were on June 6th, these would have been within the Brazilian Air Force search grid for June 1. (Red dots represent a body(ies).
The plot of the recoveries on June 7. The VS is marked in yellow.
June 8.
June 9. (These and all subsequent recoveries are now north of the latitude of Tasil).
The surface current between June 1 and June 6 centered on 3N and 30.5W, as prepared by the French Ministry of Defense.
The surface current between May 31 and June 4, centered on June 2
The surface current between June 5 and June 9, centered on June 7 (NOAA/NASA charts).
All the above charts and plots strongly suggest that AF 447 deviated to the west. How far west and on what heading it flew remains conjecture.
