What (how) and the Why´s
At this time i guess they yet known what (how)* occurred during the more important last 40+ minutes of recorded data. They had time to hear CVR and see the FDR most important parameters to correlate (timing) to the Audio and "construct a global picture". And yet started the "why´s" study.
Now the many players are about to enter the "organizational turbulent climate" where huge interests are present.
With big clusters of CB´s in their path to the new, summer interim report.
In the meantime we hope to be able to observe some "wave shocks" from the accident.
I hope we could see Recommendations, etc. before summer.
* From 01:35:43 to end of recording estimated for sure after last ACARS msgs and before the next, scheduled and never received.
