Air investigators are to examine a second black box which was recovered from flight MH17 today.
The data could reveal if the pilots were aware of a missile coming towards the plane and what happened in the last few seconds of the flight if they were able to speak.
Tributes have been paid to former RAF search and rescue co-ordinator Stephen Anderson, the ninth British victim to die on flight MH17.
Mr Anderson's employer Maersk Drilling said: "It's with great sadness that we received confirmation from Stephen Anderson's family that he was on the passenger list and is presumed dead.
"Our thoughts go out to his family and we will make every effort possible to support and assist family and colleagues."
Scot Mr Anderson, 44, spent 23 years with the RAF, including running the search and rescue team at Lossiemouth in Scotland, before moving to Penang in Malaysia four years ago with his wife Joanna, 37. The couple have a daughter.
