It is interesting that the DFDR and CVR are reported as "damaged". Well they would be - it crashed - but to what extent are they damaged? The initial reports of the impact site stated wreckage spread over a wide area. This is normally indicative of a shallow(ish) impact angle as opposed to "spearing in" i.e. very steep impact angle.
By inference, the "damage" to the recorders should be less severe with the former scenario and in any case they are designed to withstand huge impacts. With this being a fairly young Bus they would also be the solid state variety so data recovery should be relatively straight forward compared to tape or wire.
If it subsequently turns out that the data was "not recoverable" then there will ineviatabley be accusations of a cover up.
I'm an experienced Bus pilot and I have to say I'm mystified by this accident.
