Recorder recovery efforts?
In the meantime . . . any news on efforts to recover the FDR and CVR?
How deep is the wreckage site?
I presume the first step would be try to triangulate the beeps with surface craft and/or remote vehicles until the batteries fade, and if that fails, to do a sonar sweep followed by underwater video survey on identified site(s).
Would NTSB bring in the Navy or private contractors to use the relevant technologies?
