So they have recovered all the bodies from a mile down but still haven’t decoded the flight recorders? I almost believe that, not. Covering up the flight recorder data only leads to one conclusion.
They have not recovered all the bodies.
In-flight recorder data analysis takes time, lots of it. It is not like a tape-recorder and you hit play-back.
Raw instrumentation and engine data and (if lucky) some cockpit recordings, they all need to be extracted and assembled and analyzed. . .and that takes time to get a picture of what happened, in what sequence, what failed or didn’t, and what flight control inputs were done and if pilot initiated. . .all hard to piece together.
There is not a single place where the data is “played-back.” Need the OEM experts, from airframe to engines to the various instrumentation companies, they all have their areas of expertise and they are the ones that review their portion of the data. Huge effort.
Again, this is not a tape-recorder and all you do is hit “play-back” and the entire flight is re-created.
