Aviation expert Paul Beaver: "One of the concerns of the investigators is that they won't get everything they should have had"
Wreckage
from the site where Malaysia Airlines flight MH17 crashed has left
rebel-held eastern Ukraine heading to the government-run city of
Kharkiv.
The pieces are being transported by train, overseen by Dutch experts. The debris and unidentified human remains will be taken to the Netherlands for examination.
MH17 was shot down in July, killing all 298 people on board - mostly Dutch nationals. Russia-backed rebels have been blamed, though they deny it.
The exact cause of the crash in eastern Ukraine has not been established.
Lack of security at the crash site, near the village of Grabove, led to weeks of delays, but a deal made with local militias eventually allowed the removal work to begin.
Parts of the plane were found 8km (5 miles) from the main debris site
Nine of the victims are still unaccounted for.
New amateur footage purports to show the immediate aftermath of the MH17 crash
Ukraine and Western countries have accused pro-Russian rebels of shooting the plane down with a Russian-made missile, an accusation which Russia denies.
The Dutch government has taken the lead in the investigation.
Access to the crash site has been limited by the ongoing conflict in Ukraine
Investigators plan to reconstruct part of the aircraft
The disaster came just months after another Malaysia Airlines plane, MH370, vanished en route from Kuala Lumpur to Beijing.
