Debris field

Illustrated in BBC-article. (Tail section is apparently among debris which broke up first, according to media reports; not clearly shown on maps so far).


  • The burnt wing is upside down. (May be from 2014 in Algeria?)
  • The nose section is intact. Cockpit roof is crushed, cockpit came down upside down.
  • The tail section came down intact in upright position.
  • Flight data (above) suggests that pilot struggled to ascend (not clear exactly why), but the plane stalled and went down into a spin. That could eventually rip off the tail section. But an explosion on board is not excluded as well. So far, some contradictory and confusing information. An investigation will be conducted, and Airbus representatives went to the scene. Wreckage and black boxes are recovered. So we will know, in the end.
  • An investigation area is currently 16 square kilometers, suggesting that the plane broke up before hitting the ground.

Past tail strike

This official incident description is said to involve the same plane. Indeed, past registration record confirms that this is the same plane.

Hole in Tail Section?

Lifenews, 9.11.2015

Employees of the investigative bodies and special services, conducting an investigation into the causes of the crash Airbus 321 on the Sinai Peninsula, found in the wreckage of one of the tail section of the liner a strange ragged hole. According to preliminary data, it is from this point, located directly under the keel (part of the tail ), could begin the destruction of the whole body of the plane.

(Quick in-field tests did not show a common explosive residue in that area...)

Scratched or Cracked Rudder

Scratched or Cracked Rudder Photographed 6 months prior to the crash

(Rudder failures resulted in some crashes (2001) and some survivals (2005). If rudder fully turns in error, it will give a yaw and roll, which may send a plane into a dive. In 2005, pilot was able to correct this by other controls).

Black boxes

It is said ( quoting its 'close to investigation sources') that data recorder did not provide clues. It was in the tail. Showed normal work; than all data stopped, apparently because the tail separated.

Voice recorder was damaged and was not read yet.

There is one other recording device, for daily updates on system and crew performance; it was in the cabin and not protected or fireproofed; apparently destroyed in the crash.

Different version of data recorder information appeared earlier, quoting Egyptian sources-engine explosion was blamed.

Heat flash

Sbirs and DSP satellite capabilities

"Satellite detected heat flash at time Russian jetliner went down", CBS, 2.11.2015.

CBS News' national security correspondent David Martin reports a U.S. infrared satellite detected a heat flash over the Sinai at the time the Russian plane went down. The data is still being analyzed in an effort to determine what caused the flash. One possibility is a bomb, but an explosion in a fuel tank or engine as the result of a mechanical failure is also possible.


It is said that injuries of passengers in front and back are different, blunt trauma, broken bones and blood loss in front; explosion-type injuries and severe burns towards the tail, according to lifenews. Reliability of this report is unknown, no official release so far.

Elements not related to aircraft structure

  • TASS, 3.11.2015

    Experts have found in the area of disaster elements not related to the aircraft structure," - a spokesman said. "They were sent for examination," - said one of the sources. Official confirmation of this information is not available to TASS.


TASS quoting Reuters, al Masri al Yaum, Egiptian investigators: powerful explosion (caused by bomb or fuel explosion) in an engine, simultaneous failure of both engines, fire in parts of the body, disintegration of the plane in the air and quick fall.

During preliminary search, explosive traces were not found. Sand is searched to determine whether it was a bomb, according to Reuters.

CNN: "U.S. intelligence: Bomb likely brought down plane"

    British and U.S. officials said Wednesday they have information suggesting the Russian jetliner that crashed in the Egyptian desert may have been brought down by a bomb. Intercepted communications played a role in the tentative conclusion that the Islamic State group's Sinai affiliate planted an explosive device on the plane, said a U.S. official briefed on the matter. The official added that intelligence analysts don't believe the operation was ordered by Islamic State leaders in Raqqa, Syria. Rather, they believe that if it was a bomb, it was planned and executed by the Islamic State's affiliate in the Sinai, which operates autonomously.
    Two U.S. officials told the AP on Tuesday that U.S. satellite imagery detected heat around the jet just before it went down. The infrared activity could mean many things, including a bomb blast or an engine on the plane exploding due to a malfunction. One of the officials who spoke condition of anonymity because they weren't authorized to discuss the information publicly said a missile striking the jetliner was ruled out, because neither a missile launch nor an engine burn had been detected.

The black boxes made it possible to clearly hear the sound of an explosion during the flight...explosion was not secondary to engine failure

Russia says it does not have a confirmation of an explosion, says what it has is presence of undetermined sounds picked up by voice recorder. It is too early to say what is the nature of that sound, even less so to claim that it has to do with an explosion. Russia requests evidence from Egyptian and French investigators TASS


F.B.I. to Help Russia Investigate Plane Crash in Egypt, NY Times, 7.11.2015

While it is possible that Russia needs the F.B.I.’s experience to help solve the mystery of the crash, the Kremlin may have seen the cooperation as another opportunity to be engaged as a partner.

Looks like they can use some help as it seems they are not finding definite forensic clues one way or another fairly quickly; this may speed up investigation. Not seen so far in Russian press, it is Egyptian investigation welcoming help rather.

    A grainy mobile phone video circulated online purports to shows the moment the airliner exploded before hurtling down to earth, but its origins are unclear and it could not be verified as authentic. However, it appeared to chime with accounts from eyewitnesses who said the plane fell flaming from the sky.
    Yves Trotignon, a former French intelligence agent, noted that ISIS's claim of responsibility was vague in detail. "The statement does not say they shot it down, but that they destroyed it," he told Le Parisien. "You could imagine explosives on board, or sabotage."

    US officials have told NBC News that the Pentagon intercepted "detailed chatter" shortly after the crash of the Metrojet A321. That communications was allegedly sent between IS affiliates in Sinai and the group's self-proclaimed capital in Raqqa. According to unnamed officials, the communications allegedly included boasts of taking down the airliner.
    "They were clearly celebrating," the officials told NBC. The officials say that additional communications intercepted before the crash warned of "something big in the area."

Islamist chatter

  • British extremists linked to jet bomb: London & Birmingham voices heard cheering disaster - JAMES MURRAY, The Express, Nov 8, 2015
    GCHQ, the Government’s secret listening centre, picked up “chatter” from extremist groups in Egypt immediately after the Russian plane came down. The regional accents suggest “a definite and strong link” between British extremists and the attack, according to intelligence sources. “Jihadis in the Sinai area of Egypt could be heard celebrating,” one source said yesterday. “A closer analysis of that material has identified London and Birmingham accents among those numerous voices.
    “There has also been some internet traffic suggesting that there was British involvement in the attack. This was a very sophisticated, carefully planned operation involving many moving parts. “We know there are British jihadis in Egypt fighting with members of Islamic State. They were trained in Syria and are now hardened terrorists. Some of the Britons have an electronics background and have been developing some very sophisticated bombs.

The lady doth protest too much, methinks.
Some unknowns here, wild vertical moves on flightradar --but said to be steady autopilot climb on data recorder. Chemistry issues: in-field equipment tests for known, common residues. Apart from common explosives, the author lists nitrates (oxidizer), peroxyde (oxidizer), chlorine, bromine (oxidizers) . Those are not even all common oxidizers, and does not tell about uncommon.
