Dutch censor MH17 black box, page-17

when you view the footage of the crashed flight MH17,
in the smoke you see long strips of chaff drifting down...
i thought was is that???....looks like anti missile defensive chaff ...

hence i believe the pilots were alerted to/of the approaching missile
and activated the only defensive system they had. the chaff..
unfortuneatly it was a proximity detonating missile

so i believe there could be recorded dialogue on the black boxes
pertinent to the last moments...
they knew a missile was approaching, but could not have known who from...
since it had no insignia ,wore a mask,and had no identifying numberplate,
they may well indeed thought it was ukrainian...
but it was putins rocket...havent more than 10 ukrainian planes/helicopters been shot down,
how many have ukraine shot down???zero???
