Investigators probing the flight MH17 disaster are to examine a second black box.
An international team working in Hampshire conducted an analysis of the cockpit voice recorder from the downed aircraft on Wednesday.
The Dutch Safety Board (DSB) said: "This will show whether this recorder also contains relevant information, in which case the data from both recorders will be combined."
It is possible that the information handed over to the Dutch could give an indication of whether the pilots were aware of a missile coming towards the plane.
It may also determine if what happened in the last few seconds of the flight could be disclosed in any words the pilots were able to speak.
The mother of the three Australian children killed on flight MH17 told a memorial service her "arms would always be reaching for them."
A woman has apparently posted pictures of herself on social media with mascara looted from the Malaysian Airlines flight MH17 crash site.
A large section of plane wreckage and everyday carry-on items like chocolates remain scattered among the wild flowers at the crash site.
