[Baron von Kriterium]

A leak (UKR) from the Ukrainian side of the investigation gives some hints on how the plane came down (machine translation):

"We took up the restoration of fragments of the aircraft. It was necessary to determine how these pieces of metal dumped into a huge pile should be interconnected.

The intrigue remained until late. The fact is that there were no damages on most parts of the aircraft. There was no explosion and no fire in the engines or on the wings. It is possible that the plane could fall almost intact. Unlike the remains of the Boeing MN-17, there were no immediately visible signs of defeat by combat elements on the fuselage and wings. A lot of damage to the case is the result of a fall. But after laying out all the fragments of the aircraft, it became obvious that the bottom of the cockpit was missing.

Among the wreckage, fragments of the upper part of the cabin were identified. And then the find finally took place - at about 22 hours. On a fragment of the cockpit, we found holes in the damaging elements of the warhead of the rocket, which pierced the skin. We found! For the first time, direct evidence appeared in this case, which made it possible to prove what caused the death of the aircraft. For us it was a turning point.

So what we now understand:

Russian anti-aircraft missile "Tor" hit the liner in the lower part of the front of the fuselage, directly under the cockpit.

A direct hit and the cabin flared up inside. Instantly turned off the transponder of the aircraft, which gives signals about the flight. Instantly lost contact.

While there is no data, one or two missiles have caused such damage. It is possible that the second missile also hit the fuselage from below close to the first. But all this remains to be clarified.

We continue to lay out fragments of the aircraft until the complete collection of all surviving parts.

We expect that today we will gain access to all objective control data.

In cooperation with Iranian colleagues, we get the impression that those who contact us sincerely want to help themselves and figure it out, in general, there are no problems. Let's hope that such a mood and working contacts remain with us now."
