Here is my guess why it is "unusual":
- BEA receive CVR 0945 day after accident
- BEA Press Conference ~1630 same day by which time they are just realising what seem to have happened. Director keeps very guarded.
- BEA listen to CVR, under standard conditions a few more times, and cannot alter likely conclusion
- BEA, iaw ICAO (? French Law?) realise this is likely to be a "criminal act" and are forced to consult, even hand over to Police / prosecuters.
- This is where it goes "wrong". The Police/prosecution chain is not as practiced or secure, and by that evening, it has leaked to the US News Chaneels which we all wake to next morning
- 2 plane loads of relatives arrive in MRS, Prosecuter has to brief them on findings.
- Prosecuter holds news conference ~1000 to confirm earlier News Reports
We have heard, I believe,
nothing from the BEA since that first Press Conference? So I suspect the whole thing is partially (or wholly?) out of their hands for now?
Anybody who knows more about police / air accident investigation protocols please chip in. 9/11 similar where FBI did most, NTSB pretty quiet.
