Nothing to do with Indonesia - it is the lackadaisical aviation industry way of dealing with disasters. There is no technical reason why CVR and for that matter DFDR data cannot be streamed into remote storage, the communication bandwidths available now are sufficient. Instead the aviation industry prefer to use barely 'survivable' recorders with cheap short range pingers with cheap short life batteries. Like the ELBs that never seem to work these recorders are antediluvian and need to be replaced. Just think if both DFDR and CVR recording had been retrievable from an online escrow system a lot of the current speculation would not have happened. And, either the 737 Max would be grounded or MCAS could have been completely exonerated within hours of the crash. MH370 would not be a mystery and AF447 would also have been properly investigated within a day or so rather than years. Billions of dollars could have been saved.
