@sk999 ... On recovery...
Egyptian authorities stated that the vessel John Lethbridge is making a map of the different subsea area's. A map or maps that can be used for the recovery later. If they decide on doing that later.
Decision on if, and what, and how, will be recovered will probably have to wait for the first analysis of the recorders. And be supported by the photo mosaic and various maps.
Gear and data processing capabilities on board of that ship, including 3D sonar imaging, can easily cover the depths of around 3,000m. This based on the published specs of DOS.
