EXIF times of photos of MH17 crash site
Pavel Aleynikov made the two famous photos of a white smoke trail what could have been caused by the BUK missile which shot down MH17.
He made the two photos from the balcony of his apartment. Then he went to the roof and made photos of the MH17 crashsite.
Unfortunately the RAW format photos are not made available by Pavel to the public.
However, the exact times of the photos of the crashsite were made public. I requested Bellingcat to contact Pavel to request the times. Pavel did hand over the exact times to Bellingcat.
Using the times, the windspeed can be estimated.

The light grey plume is very typical BUK launch plume.
I have found several similar.
(BUT it is almost miracle if plume is visible minutes after launch)
The only/main difference is the direction.
Normally, in training, BUK is never launched to / over photoghraphers, for safety reasons.
