Investigation of the impact damage due to high-energy objects on the wreckage of flight MH17
14|NLR-CR-2015-155-PT-12.5
2.5 Number and density of hits
The total number of hits of all types of impact damage on the initially available wreckage was counted and found to be 304. After this, additional parts of the wreckage became available. Accounting for the additional hits on these parts the total number of impacts is assessed to be more than 350.
Extrapolating the number of hits on the affected area of the fuselage and accounting for the structure that was not available gives an estimate of the total number of hits of high-energy objects of over 800.
The highest density of hits was on the middle window on the captain’s left-hand side of the cockpit (window number 2).
Figure 11: Left cockpit window 2 layer and location (Source: DSB)
The cockpit windows are made of multiple layers of glass and plastic and one of the layers of this window was recovered. See Figure 11 for this window layer and its location in the cockpit. The density in this area is calculated to be around 250 hits per square meter.
2.6 Size of penetration damage
On the piece of cockpit skin with the highest number of penetrations, the size of the holes caused by these penetrations was measured (Figure 12).
Only the damage that was assessed to be the result of single objects fully penetrating the plate was taken into account. Of each hole the dimension perpendicular to the impact direction was measured ( Figure 13).

Only this dimension gives an indication of the size of the object that caused the damage. The larger dimension, parallel to the projection of the impact direction on the plate, is the result of the speed and the angle at which the object impacts the plate. As can be seen in Figure 14, the size was found to range from 6 mm to 14 mm.
The selection of 31 holes from 350 impacts
The critique on DSB is it has been cherry picking from the data to construct the bowtie scenario from 9N314M:

The critique on DSB is it has been cherry picking from the data to construct the bowtie scenario from 9N314M:
This led to this histogram:
(..) By the way, the reason the DSB showed extreme hesitation with collecting the wreckage (only got there in November!) I explain by them realizing that the more holes they’d pick of the wreckage the harder their job of stitching a Buk bowtie warhead to the case would be. The DSB hoped that some evidence would disappear and their job would be simpler. The DSB also were not trying hard to bring other parts too, as, for example, they only brought to the hangar the “Separatist scorpion” piece only after RT issued a report on them ignoring the evidence with the bit mentioned.

To me it seems that the Il86 piece has still higher hole density than the Mh17 piece. Do you agree with me?
We know that the DSB had placed the detonation point too far away. The likely reason was to equalize the observed hole density to the hole density of a Buk warhead, if it was placed at the detonation point. But the higher observed hole density on Il86 tells us that they were not very successfully at the task, and the detonation point needs to be moved even further away to match Buk (while the stringing method and the damage cover area tell us the the detonation point needs to be moved 2-3x closer).In a nutshell, if calculations were done thoroughly and honestly, they’d show that the kill weapon warhead contained a lot fewer number of fragments than a Buk warhead. One can almost see the DSB’s hard job of balancing between various BADs to justify a Buk warhead as a kill weapon.
The albert_lex report

http://albert-lex.livejournal.com/68374.html
What you’re calling the VK report is perhaps better known as the
albert_lex report or the Albert Naryshkin report. If you check the
document properties the author is “Uzzer” and the title is Министерство
обороны Российской Федерации (Russian Ministry of Defense).
The report’s string analysis and hole analysis have already been discussed. It probably would be more widely discussed if it was available in an accurate English translation.
Even with its language limitation the report annoys Buk conspiracy trolls and forces questions to be asked such as “How could a 70 kg Buk warhead detonating 3-4 meters away produce the pattern of damage seen on the Boeing’s skin?” and “How could a Buk warhead detonating 3-4 meters away produce grazing marks that point to a detonation point about 1 meter away?”
As for the credibility of the AA test, no amount of transparency would have removed all suspicions that it was a less than honest experiment. Questions would arise if the experiment was repeated with DSB/JIT experts on hand and broadcast live by all networks. Buk conspiracy theory trolls would ask, “How do we know AA didn’t tamper with the warhead?” and demand the impossible — for AA to prove a negative.

It seems you have different quality standards for different versions.
Buk version is built only on the impression created by pictures, videos, social network messages and dilettantes’ work – very fragile things to make conclusions. No hard facts support it. It IS a “bullshit story”.
Because the undoable things (that is the damage with ballistic and math applied) are against it:
– the real point of blow is 1.6-1.8m from the cockpit;
– the hole density (the number of holes) points to a smaller (than Buk) warhead;
– some holes have the size ~30mm;
Easy to check. So i have to point you that the right approach in any investigation is to make conclusions from facts not vice versa

The albert_lex selection of 186 holes
(The albert_lex report published by a Russian journalist Albert Naryshkin)
Without the amazing research of albert_lex we had no possibilities to do scientific research on the holes in the fuselage of the MH17. For this we are grateful.
Albert_lex took a much bigger sample of 186 holes out of 350 to measure the transverse dimensions perpendicular on the direction of impact:

From this histogram we derived the following square. This fragment can impact on a target from all points of a sphere:

Yes, a cube can leave a hole that’s a bit rounded if it strikes at the right angle, as Basic D illustrated:
https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiZFGqLylNPJ3ZvpNaUjSihLuk8hORfN-aLv6Efu9aBEs0jZv_RsCyaK0Fjxp0LYkfk0GcspClGOKChZb6vO2ahGGQxJYIuYHLyD9-m3S0RNwu4NM_KczripLIG-3MKlriTw9ZhCebsM9Q/s1600/Almaz-Antey+%25282125%252C5%2529.png

And fragments that are placed beside each other in the warhead would be expected to strike the target at almost the same angle. That might explain the presence of a number of ’round’ holes close together on the 777.
It would also appear to make more sense for the missile maker to use fragments with sharp edges, which are better than spheres at puncturing an aircraft’s surface.
Still, It’s strange that there are hardly any holes with a distinct rectangular shape. There are more round or oval holes, like under the window shown here:

By rotation of width = 8 to the hypotenuse the width of a rib may become larger 9, 10 but not smaller. Only diagonals will become smaller after rotation 11, 10, 9:

Above we have rib categories 8 (64) and 6 (33). Categorie 10 (30) might be from diagonals, as all diagonals come to the right or the left of the rotated ribs.
Somehow nature arranged the angles of impact from the square into less than 15 categories. What is the mechanism? That will be explained later.
As said, Albert_lex results suggest a parallelepiped of 8x8x6 mm, which is about the content of the Russian warhead 9N318 (8x8x6.5 mm), if it has to be a BUK. Though 6.5 mm differs only slightly from 6 mm, it is structural. Which means most transverse measures must be wider than 6 mm, for a rib cannot be smaller than its width. That's why the Russian warhead 9N318 (8x8x6.5 mm) is questionable. I think 9N318 is falsified by this histogram.

To proceed with the sample of DSB, their histogram has been recoded into the format of the albert_lex histogram:
Old Ukrainian warhead 9N314
Proceeding with the albert_lex research.
Following the histogram of albert_lex we can forget about the old BUK-warhead 9N314 because category 6 (33) is missing:

Suppose it was an A2A missile, what type? What type has the characteristics which can make the damage as we see on MH17?
I have not found any weapon capable. What do we know of fragments shapes and sizes of A2A weapens? Not a lot.
There is a lot of circumstantial evidence which shows a BUK is not likely. But this is not common knowledge and in the public debate it has no status. It is also too complicated. Therefore, it is important to reformulate all arguments in a simple way so that people will understand. Most importantly, we must make a statement just at this moment of the MH17 investigation. It must be before JIT comes in summer with all kinds of allegations concerning the use of BUK. If we succeed to relativize or even refute the role of BUK then whistle blowers likely will give us the right types of SAM or A2A sooner or later. That is not our task, not at this moment of time.
