The aviation industry is averse to change. Most planes are still being updated with floppy disk.

But I agree. High end commercial solid storage, such Optane, would likely exceeds the requirements needed by the aviation industry.

I understand the aversion to change (no change = wings stay on, change = wings come off?), but I feel adding an additional CVR storage should be low risk - not even necessarily the official armored/blackbox CVR, but say on the quick access recorder - on the basis that the black box CVR is likely more likely required in an instance where the aircraft did end up in a position where the CVR does represent the end of recording.

The existence of extended CVR length would also make the access to poppable breakers for the CVR less important and less error prone.
