It would be great help to investigation if they reveal where the BUK launcher with the removed identification number & missing missile is.
The greates help to the investigation would be if someone came, loaded the wreckage on trucks, and transported it to some hangar to conduct a proper investigation.
A chemical analysis could provide evidence of explosives or the abrasion of projectiles.
A blast pattern could be established.
The breakup could be put into context with the timeline.
According to one of the videos, the military of Donetsk's Peoples Republic would grant free access.
But noone is interested. No dutch team, no americans, no EU.
On what are the investigators working now if they are some 3000km away from the wreck?
On the other 777 they are spending millions and millions to find at least a little piece, but on this one they try to write a report without research.
Looks like all "proof" will be supplied by "government sources"...
Whatever the outcome of this investigation will be must be doubted.
PS: Just imagine what it must feel like for the locals to have all this bent metal on their fields, and to have to look at it every day.
