Many eyewitness stated they saw one or more Ukraine SU-25 aircraft flying over the area where MH17 crashed. An overview of eyewitness in this post.
Dutch Safety Board stated they did not interview any eyewitness despite the recommendation of ICAO Annex 13to do so. There are no primary radar recordings available. Ukraine military radar was switched off at July 17 as no flights planned. Civil primary radar was having maintenance at July 17.
While DSB concluded MH17 cannot have been shot down by a military aircraft, it seems SU25’s played a role in the disaster.
The Dutch government stated in December 2015 it will not send a letter of complaint to United Nations and ICAO about the missing radar recordings.
Only one photo is available which could show an aircraft flying over the area where MH17 just crashed. The photo was obtained by Max van der Werff from a source close to the photographer. The photo is discussed at Max website.
Mind the time shown in the photo is likely to be incorrect.
I invite anyone to determine if the photo is fake or not.
This photo shows a zoom in. It is very hard to even spot an object, let alone to determine if a plane can be seen.
Mind Ukraine Airforce has a couple of SU-25s flying in a lightgrey camouflage.
