I have read several NTSB reports where the Black box had "no data" recorded. In two cases the FDR did have information, but the CVR box was relatively undamaged, yet the tape was blank, in one case the CVR has (had) a switch that was acutally open, and had erased ALL the recordings on the tape. Is the tape checked daily, monthly during 100/300 annual MX checks? Or are there special tech's that remove and goes over the CVR/FDR to ensure functionality?. I know that they are well protected, but is there easy access to them? I would assume this would be, in some cases, the only way to see what happened to the aircraft that crashes with no last radio call, or over the ocean etc.. (I am speaking here of Commerical/Military aircraft, that by FAA regulations, require such recorders). Thanks,
