Apparently, we're not the only ones trying to figure out if its the FDR or CVR - just heard on Radio NZ that "the authorities now say they are not sure if its the the CVR or FDR"
On another note, I was surprised to see the FRD/CVR being handled by Chief of the National SAR Agency. I thought these things needed to sit in water (if recovered from undersea) and be carefully delivered to experts who painstakingly ensure a careful process is followed, not being waved around and brandished with bare hands in the dry in a manner that could see it in any way compromised/dropped/shaken etc. Just classic grandstanding or am I missing something?
