Since I am on the first day since the death of Malaysian "Boeing" Practicing version that the plane was shot down by Ukrainian Su-25, then I can not not publish a new investigation summarizing the arguments on this topic.
In the ruins of the MH17 found stem from the rocket "air-to-air" P-60M
In Holland model composed of fragments of the fallen in Donetsk "Boeing". From the photographs of debris from the crash site, you can make a rough reconstruction of the airframe. Among the photos were found at least two that refute the version of the attack aircraft of complex "Buk". One photo shows an object like a rod from the aircraft missile R-60M, and the other - a round hole in the air intake of the right engine. There are at least nine hole plating, characteristic for the action of a missile "air-to-air".
Round, square, rod - that has got to Boeing
early in the coming week, 3rd, 5th and 6th March 2015 nearly five thousands of people - relatives and friends of the victims "Boeing" in Donetsk - see collected from the wreckage of the aircraft model Boeing 777 Malaysian airlines at the airbase Gilze-Riyen in Holland. The last large fragments, a truck, are still in the Peter and Paul Fortress - Dutch journalists were able to get to them only 22 February 2015. UPD Photo airbase 03/03/15
The right side of "Boeing" The greatest attention immediately attracted the left side of the cockpit, where the plane had a large amount of damage. The biggest hole in the center of the fragment has torn edges, curved outwards, which is typical for an explosion inside or decompression due to a sharp drop in pressure. Further, in the photo, we see more than 20 large holes of round shape, samples including glazing frame and the left side of the cab . Sheathing material in this site the most dense - it is made of reinforced aluminum (according to other sources used titanium plates), laid in two layers in order to prevent damage to the car when a possible collision with a bird. According to some reports, the thickness of a single layer sheet - 1.8 mm, the other layer - 0.8 mm. We also know that most of the thickness of the skin of the fuselage "Boeing" -777 - only 2 mm (0.09 inches With increasing photos we see a lot of small otmetin- "craters" and black soot stains on the outside of the cabin and the outside edge of the curved outer skin. This indicates that the striking shell exploded in the vicinity of the aircraft skin. According to some estimates, the distance from the cockpit to epicenter of the explosion could be as low as 50 cm to 4.5 m . Then the radius of the affected area "BUK" - 17 m, the rocket explodes in front of and above the target, making the hill, and creates a large cloud of six thousand fragments ( source ). Quote from mh17webtalks : detonation products - they left countless tracks on fragments of the cockpit - lose their ability to cause mechanical damage (lose kinetic energy) at a distance from the point of undermining equal to 15 ... 20 radii checkers explosives. Accordingly, at a radius of 10 ... 15cm, it is - 1.5 ... 3.0m .... From the beginning of the explosion blast wave forward runs, followed by hot gases, and then, as more massive - fragments. But gas is rapidly inhibited, so it should be available only near the site of the explosion.If the range of undermining "BUK" does not coincide with the image, it may have the right size holes? To find the diameter of the holes in the casing of the cabin, we need to know the diameter of the cap standard aviation rivets. It is equal to 0.488 inches or 11 mm. correlating parameters, we obtain a width of 20-30 mm holes . The diameter of the circular openings in the casing at a rate of 2-3 cabins with head diameter rivets aviation. In the first photo in a few holes barely visible yellow-red region - perhaps a trace of copper shell try these holes projectile. ( With the introduction of the bullet into the target it, pushing part material obstacles and pushing forward its leaves already on the particles formed by the hole on. Poyasok wiping width of a few millimeters leaves soot particles shot rifle grease, metal particles from the trunk and the most bullets). However, fission "BUK" no copper, but it is on the equipment of aircraft guns. The tape armor-piercing and high-explosive charges in aircraft guns, missile elements of cylindrical shapeVisually here. How to shoot cannons GS-30 Apart from a few tens of round and oval holes in the front of the "Boeing" there are at least five holes that are rectangular and square shape . However, none of them fall into the casing directly from the outside, therefore their size is difficult to determine. But we are talking about the size of more than 1 cm. In describing the characteristics of the rocket P27, for example (can also be installed on the Su-25), according to the presence of a missile ready cubes on top of the rods. Former Air Force servicemen of Russia and Ukraine on their forum wrote, that R-60 is equipped with a tungsten rods besides also ready fission (a similar description of the fragmentation and rod warhead and have other sites ) (large images warhead training missile R-60 ). In addition, none of the known from photographs holes on skin of the aircraft, including the cockpit trim - not the same as the last image element. Attention is also drawn lining the side of the cockpit. Charge high-explosive fragmentation warhead can be included in a variety of surfaces, "Boeing" at different angles. Depending on this shape will change and the hole - for example round (in contact with the spherical member at a right angle) to an oblong (acute angle). Here's how it looks in contact with the metal in a simple cartridge. Perhaps this is due to the presence of holes of different sizes on one of the pieces of skin on the side of the cockpit (item 4 in the diagram on the left side of Boeing ).Comparing with heads of rivets, the size of these holes ranges from 3 cm to 10 cm in length. Angle shards can be equal to 25-30 degrees. How to Shoot "BUK" Rocket 9M38M1 used in complexes "BUK -M1", consists of a high-explosive fragmentation warhead weighing 70 kg 9N314. At its foundation included 32 kg submunitions (4500 items weighing 8 g in the form of an I-beam (average between the letters H and X) and 1500 blocks weighing 4 grams). Source The network has a photo of one of the combat units missile system. Shards-Beams - 13 mm. Diameter of less than 10 mm cubes. Source andmore If the attack on the "Boeing" used this kind of rocket "Earth-Air", the majority of shrapnel holes had to leave characteristic traces of rectangular shape (I-beams have the best performance penetrating power than cubes). One of the users "LiveJournal" conducted an experiment - that's what had to leave traces "BUK" in the skin "Boeing" if at least some fragments of 4500 flew into it at an angle close to right. A detailed description of the experiment HERE . found on the wreckage of "Boeing" in the skin of the aircraft are no similar holes with a similar size. And, as the author of the experiment, on the thin material of the fuselage debris flying at a speed of 1200 ms, should leave a clear footprint than for example in the casing of the cabin with a reinforced aluminum layer. With correction for high-explosive charge and angle defeat fragments "beech" in the skin can leave traces of diameter 18-20 mm. Read about the real dimensions left by high-explosive shells holes can be here , here and here.The two found in the cockpit square fragment exposed - one turned out to be made of ceramic, the other did not coincide in beveled edges. What is the firing aircraft from "Buka" The network has photos of the wreckage of three aircraft shot down over the last 15 years, presumably because of anti-aircraft missile systems "Buk". In all cases, the crew remained alive even some -That time after the missile strike. In all cases, the aircraft skin looks about the same - a lot of small round or cross-shaped holes. Read more here. Fragments of the AN-26 was shot down in Ukraine July 14, 2014 at an altitude of 6500 m. It is well known that the June 29, 2014 Year militia seized the military unit 1402 in Donetsk, where there was a faulty installation "BUK", however, while representatives of the DNR said that is not going to fix it. We know for example that the existing arsenal of Ukraine complexes "Wasp" is also able to achieve goals similar to AN -26 or the Su-25 at an altitude of 6000 m. The holes in the form of rods. One of the bars found in the wreckage we see at least three cutting holes: on the left wing, near the second door on the left, on the elements of the tail section (see. diagram left side "Boeing" ). For example, a hole in the skin next to the second left door has a length of about 10 cm. Left wing Gender in the booth next to the second left doornext to this hole and the "cut" along it frames find elongate member that looks like a piece of rod warhead missiles aviation "air-to-air" P-60M.

SUMMARY The Su-25M1 missile R-60M
Material rod warhead - an alloy of zirconium and molybdenum / tungsten. Battle of the relatively low power, maximum efficiency in penetrating into the structure of the aircraft target. Fuse - proximity of radio controlled fuses "Hummingbird" (developed in 1971) and contact backup. Radius of radio controlled fuses tripping - 5 m. The radius of destruction - 2.5 m. Source
Here is a description of warhead R-60M (62M product). It differs from klassiecheskih long thin arrow-shaped rods, export version is a set of "psevdosterzhney." Submunitions are made of heavier tungsten. "Gush striking elements of tungsten, twice heavier than alloy steel, cut the power and set the wing or the airframe and engines," - said in the description of the warhead R-60M. Some sources indicate the mass of the rods - 3 years Weight warhead - 3 kg. Laying rods made in the body with a triangular trim - rods, probably have a triangular cross-section: " The space between the shell and core of the GGE filled with TNT having pyramidal recess next to each housing a semi-damaging elements ... Pieces of weight 3g, accelerated to a speed of 7,5km / with. " (Source) "The rod warhead R-60M (62M) with tungsten rods, stacked perpendicular, let's not linear, and the huge delta, or diamond-shaped holes.
Exports included only the P-62, and since the 80 P-62M, 70% had both missiles fragmentation (or "psevdosterzhnevuyu") rather than a rod warhead.
Large incoming delta-torn holes we found, for example, the right side in the casing of the second cabin. One of them is visible trace of soot. Furthermore, two similar holes visible in the floor of the luggage compartment near the front of the cockpit.
Six delta and diamond-shaped holes and cutting three holes on the left wing and the lower portion of the skin adjacent to the second left door:
shaped openings coincide with lesions of combat of the P-60M installed on Su-25M1,
the missile could be induced on the motor "Boeing", but explode at 5 m from it, including near the left wing and the floor at Exit L2 - where found two typical rod holes. Ukrainian software "Arsenal" is modernizing missiles. Rockets was established almost vserakursny infrared guidance system OGS-75T "Mosquito-M". ( Increase angle to 2/4 or even 1/4 (possibility of starting in the forward hemisphere purpose bearing at a certain angle) cools the photodetector GOS. Series production was carried out NPK "Progress" (Kiev,source ). The angle of targeting - Sector 34 degrees. The rate of displacement of the maximum goal - 35 deg / s ).
It is also possible that after activation lifting charge at maximum approximation to the "Boeing" warhead opened, and the support of the P-60 hit the inside lining "Boeing" in the area near the landing gear motors .
"Fragmentation rod warhead mainly used for air-to-air missiles due to compactness. At the peak of approach to the target, the warhead is made podryv lifting charge, and a bundle of rods on almost cosmic speed rushes to the goal. In case of contact, a pin on the kinetics alone able to break the plane through almost any plane while destroying the internal structure of the aircraft, carrying pieces avionics. The kinetics of the rod is such that he can kill two, even titanium spar. In such a warhead has another advantage - the rocket does not require absolute precision - It undermines before contact with the target, and fly rods in the direction of the plane cone. Even if directly hit the target 2-3% of these rods, the plane is doomed . " Source
How to kill "Boeing" MH17
Since the late reply MH17 crew to a loss of communication with the aircraft took only seven seconds. The crew did not have time to inform dispatchers of any threatening situation (if you believe in the authenticity of the "lost" recordings from air traffic control in Dnepropetrovsk), which means that events in the cockpit developed rapidly. After PE "Boeing" has launched, he abruptly lost speed - from 900 to 400 km.h km.ch. continue with the planned height of 10 thousand. meters to a height of about 2 thousand. meters. Residents of hornbeam and Tereza heard in the sky two very loud bang. Descended below the clouds, "Boeing" began to crumble - closest to the occurrence of emergency on board in forest plantation landed a big piece of the fuselage - part of the business class cabin and the second economy class - they are found in the Peter and Paul Fortress. Near the breakaway found loose in the cockpit, and the body more than 40 people. The tail and the central part of the fuselage with the landing gear and wings flew the farthest - in the village Hrabovo.
From July 2014 to February 2015 found the majority of Boeing debris. Not enough of the right wing and the right side of the business class, as well as the nose "Boeing". Until now identified three passengers of the aircraft. All on board were 298 people.In the body of the pilot, according to the Malaysian press, found metal fragments. Overall, 25 found metal objects that caused the investigators suspicion. Most damage from fission was left cabin trim the cabin floor, numerous holes visible in the district commander of the crew seats, a few holes - in the copilot's seat. At least four holes visible in the body of the commander. All these holes round shape.
The back of the copilot's seat, you can see numerous holes in the side and back
view of the remains of soot and many small black tochek- traces the impact of the detonation products, a missile load is here - outside the cockpit at close range.
Given the height of flight - 10 thous. meters, could reach the cabin or anti-aircraft missile complex (C300, "CBO") or missile "air-to-air." And since the cockpit are no traces of the impact rod submunitions, but a lot of round holes with jagged edges - we are talking about undermining high-explosive shells. Such shells with rounded striking elements used in cannons GS-30, as well as characteristic of the missiles "ground-to-air" S-200 and S-300. As in the wreckage of "Boeing" no cruciate tracks - the predominant elements BEECH missiles, and the undermining occurred at a distance of not more than 5 m, the version of the application "beech" can be rejected. C200 complexes in Ukraine "idle" since 2001, launching missiles C300 in the area, no one recorded.
BOEING ATTACK ON THE RIGHT "in pursuit"
So there was a version of a plane or two Su-25M1 - upgraded stormtroopers were armed with Ukraine (at the time tragedy in the Ukrainian Air Force had five of these aircraft - one of six Su-25M1 Ukrainian was shot down the day before the accident, "Boeing"). In addition to the observed in the wreckage of the object, similar to a core element of the R-60M, this version supports chip found in the piece the right engine air intake "Boeing".
Chip is inverted to us "upside down" - on the left edge is visible piece of torn inner lining, and the right side - outside, with subtle logo letters RR - if a piece of flip, it will be the upper part of the air intake RIGHT ENGINE.
This is a small hole found on the right engine "Boeing" - so say the authoritative sources Wall Street Journal . Outwardly curved edge of the opening, in which case the air intake struck fragment, arriving from the tail.
There is another piece of the engine - turbine rim traces incoming holes, but to which it belongs of the engine, set on the picture is impossible. It is known that the chip was foundin the vicinity of Peter and Paul, where he lay right inlet. However, it also found the left door, located in front of the left engine. If it is really a piece of the right engine, then shots were fired from cannons rear right, and then the right side over the side and right-hand drive in the cockpit area. Most likely, the shots were fired at close range (about 500-700 m). The right side plating "Boeing" between the cab and the second right-hand door is not found (in any case, her photographs in the public domain is not). Wall Street Journal published debris bins on the right side of the business class, and at the air base of the sleeve-Riyen journalists barred approach to precisely these fragments business class by covering their squares as objects of interest to the investigation. Source Source Su-25 (Rook) . The aircraft is a two-barrel fixed gun GSH-30 left on the board in the lower forward fuselage (caliber 30 mm ammunition 250 rounds), designed primarily to attack weakly armored targets such as armored personnel carriers. Can be additionally installed to 4 guns GSH-23L with a movable barrel capable deviate down to 30 degrees (260 rounds of ammunition), as well as two missiles "air-to-air" P-60 or P-27, in some embodiments, can be installed missiles R -77. Here is the first attack of the cannons rear right "in pursuit" - bullet punched trim engine starboard business class and fly into the back of the pilot. Details dismantled this version here. For firing cannons could be used GS-30 with armor-piercing and fragmentation -fugasnymi cartridges (See above.) caliber of 30 mm or four gun GS-23 caliber cartridge 23 mm. A few holes on the detected piece of skin cockpit and backrest of the second pilot is likely to have been damaged by fragments of not more than 20-30 mm, flying by the tail. This is confirmed by several sources (link and more ). The pilots did not see the attack aircraft in front of you - fatal injuries they received from the back. After that the Su-25 attacked the front cabin when "Boeing" has launched. This is how multiple input and multiple output ports on the skin of the cockpit. The input and output openings in the cockpit backrest pilot pilot. How are included in fabric and metal holes can be compared here , and here the crew commander's body with holes in his chest CONCLUSION: According to the Malaysian Boeing has suffered a blow combined with Su-25 M1. The first firing of the Su-25M1 was based on the flight path "Boeing" in pursuit - most likely, attack is on the right side of the tail of the aircraft and the Malaysian shot, moving in the direction of the right engine - in this direction aircraft fired several shots from cannons caliber 23mm or 30mm .After the first firing pilots died in the cabin there was a massive decompression electronics out of service, the aircraft spun to the left, and "Boeing" was probably attacked again attack aircraft, now on the left side - in the cockpit area from the commander of the crew of the cannons and R-60M in the area of the left engine and the left door, in which traces of destruction stem fragments. PS The author of the picture - Dutch RTL correspondent Jeroen Akkerman, to which I asked about this fragment topic ignored. Alas, we can only judge by the photos.
