One might even think, that with the previous accusations of "tampering" (both Habsheim and St.-Odile, for a start), the authorities want to make darn sure, that there is an unbroken "trail of evidence" showing that the recorders that will in the end get to Honeywell are the same recorders, with the same contents, that came out of the Mediteranean originally.....
Unfortunately, a "judicial enquiry" is not done with the same urgency as a "crash investigation".
Some things never change...
