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.
Downing Street officials are working with the relatives of the MH17 victims to protect them from possible financial or identity fraud.
A No.10 spokeswoman said: "The Foreign Commonwealth Office (FCO) continue to provide consular support to the families of the victims and are working with families to provide flights, accommodation and translation assistance to those wishing to travel to Kiev or Amsterdam.
"We are also working with family members to protect victims from the possibility of financial and identify fraud."
They added two UK police experts are now in Kiev meeting with Ukrainian authorities and stand ready to move on to the crash site.
Thousands of online users have taken to social media to call for the victims of the Malaysian airliner crash to be returned to loved ones.
United States intelligence officials admitted that they do not know who fired the surface-to-air missile that downed flight MH17.
