Debunked: MH17 Air to air missile Assumption ? [Unrelated 35° angle]

Can you expand upon your hypothesis slightly?

The damage indicates an 'attack' from 35deg off the nose, and the radar suggests there was a contact on this bearing?

Yes, the damage indicate an angle 'attack' from 35 deg with respect to the axis of the MH17.
And 13 sec before the MH17 diseappires from the radar the 'supposed fither' (CNA351 on the screen) has an 'angle attack' of 35 deg with respect to the MH 17 axis.

CNA351 is not a fighter:
"CNA351" is Cyrillic for SIA - Singapore Airlines flight 351 - a B777-200 (b772) at 35,000 ft (350)
This thread, the source of the above quote, goes into more detail:

Besides, to calculate the angle from radar you need to measure it between where the "fighter" was when it launched the missile and where MH17 was when the missile struck, not their contemporaneous positions.

Are you thinking the damage was caused by a machine gun?

Absolutely no. Perhaps by shrapnel(s) from groud-air missile or when the wing comes to the ground.
But the wing is slightly "cut" with two parralel lines.
Have you an opinion on this damage ?

First of all they aren't parallel lines if you look at it closely. If a proximity warhead detonated in the front of the plane, as theorized, one would expect this type of damage. If we look at the photos of the cockpit skin below the pilot window we can see how close together the shrapnel puncture holes are, here;

Then as we make our way back from the cockpit one would expect the puncture holes to space out more as the blast radiates the shrapnel outward.



Even this picture you can see minimal puncture holes from the shrapnel right below the flag

It's probably debris that was shed immediately after the aircraft was hit. The direction a missile was fired from cannot be gleaned from the direction the warhead fragments traveled.

Tanks for your answers.

Absolutely no, but can the two "parallel" slightly cuts come from the "wings" or "fins" of a supposed rocket coming from behind the MH17 and gliding along the top of the wing ?

I do think that much of this speculation RE: missile vectors and damage assessments is a bit premature...until the full accident investigation (such as can be determined) is concluded. Experts will weigh-in to add to the final reports.

I agree WW, but using some intelligent deduction I think it's safe to "assume" that there should be more "shrapnel" puncture holes and closer together, the closer it was to the missile's detonation. As the fragments radiate out from the detonation the fragments will continue to "fan" out and be more spread out from one another. So one would think the closer you are to the blast the closer the puncture holes should be together and the further away from the blast the more spread out the puncture holes should be

The shrapnel would have two perpendicular velocity components, the speed and direction of the missile (depends on the type, for a BUK it's about 850 m/s http://en.uos.ua/produktsiya/tehnika-pvo/75-zenitniy-raketniy-kompleks-buk ), and the velocity from the explosion (initial fragment velocity is typically 1800 to 2100 m/s http://fas.org/man/dod-101/navy/docs/fun/part13.htm ), so that would give an angle of about 60° to 70° in respect to the missile direction. Then there's the speed of the aircraft which is constant while the shrapnel slows down rapidly due to drag, making the resulting impact angle also a function of the size of the shrapnel and the distance the shrapnel traveled before it hit the plane...

Again, these sorts of "assumptions" do not take into account relative motions of the missile, the "target" (MH17 in this case) the approach angle OF the missile, etc, etc. It is a VERY complex set of circumstances that (alas) likely will never be fully explained/properly documented because the airliner debris field was not "secure".

The speed of the missile would cause the fragments to expand in an elongated spherical shape instead of a pure spherical shape if the warhead wasn't moving. Regardless of the missile's motion, the closer an object is to the detonating warhead the more hits per square meter it would receive. It's the basic inverse square law.

Rods would do that on a wing. To me it seems this missile was not a regular sa 11. It had those diamond shaped shrapnel and also Rods on its war head.. plus a second stage of explossives from that missile inside the cabin would also explain why the complete head secction was pulled off.

I do not know if a pechora can do something like this or a sa 17 ,but there is certainly more to explain.

The story about an air-to-air missile is looking harder and harder to explain ,because normally su 25s have heat seeking missiles and they would have searched for the turbines.. not the planes main body even less its nose. Also that angle described in the flight path departing from a supposed su 25 (a point shown in the Russian Radar presentation that doesnt travel sideways but up and down) ,how can a heat seeking missile go foward and then return 180 degrees to explode on the nose of the plane?

And the story about armor piercing or cannons/machine gun from the su 25 its very very difficult to believe ,since the holes and very small. I think only piercing ammo 5.56 could do holes like the ones found on the mh 17 but then its impossible to understand why some of those bullets did not go thru the complete aluminum windows frames that are made rather of a very soft material.

That wing scrape has to be from debris.

a)the chance of a rod or a whole missile just skimming a wing exactly in the same plane is very close to zero

b) any missile that manages to do that would MISS THE COCKPIT.... the tip of the wing is level with the windshield, so anything skimming the wing can't hit way below the windshield

c) heat damage and other directional damage indicates the missile detonation was lower (about level with the engine) and to the front.

That section is from the starboard side. It was in the first image of the crash widely posted, taken from the left side with 2 men standing on the door (near the back, in this view). The dark spots appear to be dirt or debris dents,rather than through holes.

I'd dispute the point about the elevation of the detonation based on the following picture that shows a detail of the cockpit floor (Port side) showing what I believe to be shrapnel puncture marks from *above* the level of the floor.mh17 cockpit floor.JPG

Yeap ,and those holes somehow also show the direction they came from ,i dont see holes made with pieces of ,metal flying sideways but straight down.

On the other hand.. where did all the other pieces of that cockpit go? Is the rest of the cockpit the part they sliced with diesel chainsaws?

Most of the threads discussing the shrapnel damage are locked. Recent update from BellingCat.

Another shrapnel story is currently doing the rounds. Documents claimed to have been hacked from the Ukrainian Defence Ministry and apparently show recovered Buk M1 warhead fragments.

http://cyber-berkut.net/traitors/0025.php

The spin on the story is that Russia doesn't operate the older M1 versions and therefore the Buk must have been fired by Ukrainian forces. This doesn't stand up as Russia still operates the older M1 missiles and in particular fires the missiles during exercises and tests. (See PPRuNe link in post)

One also wonders what he differences between the warheads might be - it is certainly possible that later missiles have a completely different warhead, or that incremental improvements are recognizable from fragments.
