ST. PETERSBURG, Russia (AP) — Mystery and confusion surrounded the final moments of a Russian jetliner that plummeted suddenly from high altitude to the Egyptian desert, killing all 224 people aboard. The airline Monday ruled out pilot error or a technical fault, but Russian aviation officials dismissed those comments as premature.
Some aviation experts raised the possibility that a bomb on board the Metrojet Airbus A321-200 brought it down, while others cited an incident in 2001 when the aircraft grazed the runway with its tail while landing.
James Clapper, the U.S. director of national intelligence, said that while there is no direct evidence of any terrorist involvement yet, it couldn't be excluded that the plane was brought down by Islamic State extremists in the Sinai Peninsula.
"It's unlikely, but I wouldn't rule it out," he told reporters in Washington.
Asked if a terrorist attack could be ruled out, President Vladimir Putin's spokesman, Dmitry Peskov, said: "No versions could be excluded."
The Metrojet was flying at 31,000 feet over the Sinai when it crashed Saturday only 23 minutes after taking off from the Egyptian Red Sea resort of Sharm el-Sheikh for St. Petersburg with mostly Russian passengers.
Metrojet firmly denied that the crash could have been caused by either equipment failure or crew error.
"The only possible explanation could be an external impact on the airplane," Metrojet's deputy director Alexander Smirnov told a news conference in Moscow. When pressed for more details, Smirnov said he was not at liberty to discuss them because the investigation was ongoing.
Asked if the plane could have been brought down by a terrorist attack, he said only that "anything was possible."
But Russia's top aviation official, Alexander Neradko, dismissed the company's statement as premature and unfounded.
In televised comments from Egypt, Neradko said it would be possible to draw conclusions about the crash only after experts examined the plane's flight data and cockpit voice recorders and studied the wreckage.
He said the large area where debris were scattered indicated the jet had broken up at high altitude, but he refrained from citing a reason for the crash pending the investigation.
Viktor Yung, another deputy director general of Metrojet, said the crew did not send a distress call and did not contact traffic controllers before the crash.
Egyptian officials have offered conflicting accounts on whether or not the plane issued any distress calls.
Experts say planes break up in flight usually due to one of three factors: a catastrophic weather event, a midair collision or an external threat, such as a bomb or a missile.
A local affiliate of the extremist Islamic State group has claimed it brought down the aircraft, which crashed in the northern Sinai where the Egyptian military and security forces have battled militants for years. Both Egyptian and Russian officials have dismissed that claim as not credible.
Still, the U.S., Germany and Britain all had overflight warnings in place for the Sinai. They advised airlines to avoid flying over the peninsula below 26,000 feet and to avoid the Sharm el-Sheik airport due to extremist violence and, notably, the use of anti-aircraft weapons.
British military analyst Paul Beaver said he thought the crash was most likely caused by a bomb on board, because the IS hasn't been known to possess surface-to-air missile systems capable of striking passenger planes at cruising altitude.
"That's a very serious piece of equipment, and I don't think they have that sophistication," Beaver said, adding that the Sinai desert is well-scrutinized by intelligence agencies, so a missile system would have been seen.
Robert Galan, a French aviation expert, said Metrojet's claim of an "external impact" pointed to two possibilities: a bomb or sabotage.
"Either a bomb was placed during the stopover and programmed to explode after takeoff, or a mechanic sabotaged the plane," he said. "These are the two most probable hypotheses."
Sabotage would require familiarity with the electrical or fuel systems of the A321-200, but hiding a bomb would need less knowledge, he added.
Galan said an analysis of the plane's data and voice recorders — the "black boxes" — will not confirm either a bomb or sabotage, as it records only the pilots' communications and technical readings. But he said investigators could know within 48 hours whether a bomb downed the jet because the debris would show traces of explosives.
The plane's operator has a spotty safety record and was rebranded recently in the wake of another deadly accident. The airline, registered as Kogalymavia, changed its trade name to Metrojet after one of its Tu-154 jetliners caught fire in 2011 while taxiing before takeoff, killing three people and injuring more than 40 others.
The Airbus A321-200 that crashed Saturday was built more than 18 years ago and changed several operators before entering Metrojet's fleet in 2012.
One area investigators will look at closely is whether the tail separated from the rest of the plane in-flight as the result of damage caused by a previous incident in which the tail struck the runway during a landing, said aviation safety consultant John Cox. Such "tail strikes" can cause extensive damage to the aircraft's skin in the region located by behind the rear laboratories and galley.
The incident occurred in Cairo in 2001. Metrojet said the jet underwent factory repairs and was safe to fly.
Cox said such monthly maintenance checks typically can't spot a return of damage from a tail strike because the cracks are inside the plane in an area that's not normally accessible during visual inspections.
Instead, tail strike repairs are examined during heavy maintenance checks that typically take about every four to five years, he said. Parts of the plane are disassembled so that inspectors can see inside. The plane's skin is checked for cracks using a device that employs low voltage electricity or special dye.
"That's a very complex repair and it requires very special expertise," said Cox, a former airline pilot and accident investigator. Investigators will "look not only at whether the repair done properly, but were the inspections of the repair done on a regular basis during the normal heavy maintenance checks."
If damage from a tail strike returned, it would be in form of small cracks that grow larger with the normal stresses of repeated pressurization and depressurization.
In 2002, China Airlines Flight 611 disintegrated in midair while flying from Taiwan to Hong Kong, killing all 225 people aboard. Accident investigators cited metal fatigue caused by inadequate maintenance after an earlier tail strike as the probable cause of the accident.
The Irish Aviation Authority said the Metrojet plane was registered in Ireland and regulators there found its safety documentation in order earlier this year.
At the crash site in the Sinai, emergency workers and aviation experts from Russia and Egypt searched the barren terrain for more bodies and examined the debris.
Teams finished combing a 20-square kilometer (7.7-square mile) area for bodies by afternoon and expanded the search to a 30-square kilometer (11.6 square mile) area. Russian Emergency Situations Minister Vladimir Puchkov promised they will not rest until all victims' remains are found.
Investigators from France and Germany, representing Airbus, and from Ireland, where the plane was registered, were to join investigators in Egypt.
White House press secretary Josh Earnest said the U.S. offered support for the investigation, but he added that he's not aware of any resources that have been dedicated to it so far.
"Rather than speculating on what may have led to this terribly tragic incident, we're going to allow the investigation to move forward to try to get the bottom of what happened," he said.
A Russian government plane brought 130 bodies and partial remains to St. Petersburg. The city is holding three days of mourning through Tuesday.
In his first public appearance since the crash, Putin described it as an "enormous tragedy" and said his thoughts are with the families of the victims.
Mourners have been coming to St. Petersburg's airport since Saturday with flowers, pictures of the victims, stuffed animals and paper planes. Others went to churches and lit candles in memory of the dead.
Sunday was a national day of mourning, and flags flew at half-staff across Russia.

ReplyDeleteI think that the crash of the Mertojet has no real significance to any political or extremest party. I think there is a simple explanation, and Josh Earnest feels the same way by saying,"Rather than speculating on what may have led to this terribly tragic incident, we're going to allow the investigation to move forward to try to get the bottom of what happened"(Josh Earnest,Associated Press). He doesn't want to hear all the theories of terrorist attacks, and wants to find exactly what happened for the plane crash. Not every plane crash has to have a terrorist explanation.
Paragraph 11 states, "large area where debris were scattered indicated the jet had broken up at high altitude". Before any concludings are made they need to make sure they are spot on, on with what happend so there are no future conflicts. They need to stop though with all of the terrorist attack ideas because that is just going to create fear and anger in the people which will lead to conflicts.

I do agree with the possibility of the tail coming off the plane. It seems it would be too obvious for a mechanic to hijack the plane. He would get caught. I am also leaning towards the bomb possibility. It seems easier to get onto a plane, and follow through with. Although, I still strongly agree with the possible factor of the tail coming off. There was a failed flight (611), a Chinese airline, going from Taiwan to Hong Kong. The tail had come off the plane resulting in the deaths of everyone, all 225 people. Hearing this makes me believe that it really was the tail.
ReplyDeleteI think that the claims of ISIS doing this act is probably the best explanation for the plane going down. Since Russia is currently fighting ISIS, it would make since that the attack brought down a Russian jet, especially over a country where ISIS is present. In paragraph 12 it states,"Viktor Yung, another deputy director general of Metrojet, said the crew did not send a distress call and did not contact traffic controllers before the crash." This shows how if a bomb went off, their would be no time to send a distress call.
ReplyDeleteAlthough it's tragic, I always find it interesting when a plane goes down without an explanation. I think it is most likely due to an act of terrorism. It's probably ISIS, because the two countries have been going to war and they are rival countries..
DeleteI think after reading this article that the airplane was bombed on purpose since they have been having wars between both countries. "The airline Monday ruled out pilot error or a technical fault, but Russian aviation officials dismissed those comments as premature." This is explaining that the pilot sent out a signal what was happening and the Russians just ignored the signal.
ReplyDeleteAfter reading through the article titled "Mystery, confusion surround Russian plane crash in Egypt," I have come to a conclusion about the Russian aircraft crash. I believe that the Metrojet was bombed or hit by some other sot of violent missile. The associated press states, "They advised airlines to avoid flying over the peninsula below 26,000 feet and to avoid the Sharm el-Sheik airport due to extremist violence and, notably, the use of anti-aircraft weapons" (Associated Press pg. 17). Since signs of violence were were warned by U.S, Germany, and Britain, it makes perfect sense that the jet was bombed or hit by a violent weapon. Also, there pilots of the jets did not set out a danger warning which they would have if the plane was having problems. Obviously, the jet had to have been assaulted.

I agree with Smirnov when he says that "any thing is possible". The area in which the plane was flying was warned to have violence in the area. It wouldn't be out of the question to assume that the plane was hit and taken down by a weapon. "Rather than speculating on what may have led to this terribly tragic incident, we're going to allow the investigation to move forward to try to get the bottom of what happened"(Josh Earnest,Associated Press). I think we are getting distracted by all of the possibilities of what may have happened, than by the actual facts that will be found throughout the investigation.

I believe that the the plane did not go down because of a bombing or of terrorist action. I say this because in this article it states "Galan said an analysis of the plane's data and voice recorders — the "black boxes" — will not confirm either a bomb or sabotage, as it records only the pilots' communications and technical readings. But he said investigators could know within 48 hours whether a bomb downed the jet because the debris would show traces of explosives.". Meaning that a bomb would not likely be possible because there would at least be some trail showing that the tail damage might be the cause of this event.

This certainly interesting. As stated, "Experts say planes break up in flight usually due to one of three factors: a catastrophic weather event, a midair collision or an external threat, such as a bomb or a missile." there is evidence and theories supporting each one of these options.I personally do not know much about planes, so i can not deny the possibility of reemerging damage from the past tail strike, but i am personally leaning towards a bomb or missile being the true cause of the crash. It is horrible that things like this happen, I can not imagine the pain the families of the victims must be going through. I hope that if this was a terrorist attack, that justice will be served for those the world lost that day.

Although it's tragic, I always find it interesting when a plane goes down without an explanation. I think it is most likely due to an act of terrorism. It's probably ISIS, because the two countries have been going to war and they are rival countries. Terrorism would be my best guess for the plane going down. Planes are usually on autopilot and they have many ways to make the plane safe, so the fact that it dropped out of the sky without the ability to land is suspicious.

ReplyDeleteI have a huge fear of planes but I think the past few years, more planes are going missing. In the article Smirnov said, "Anything could have happened"(Associated Press). What they are telling us, is that they do not know what the cause was for the plane. We are talking about people here, family, friends, children, love ones, and the people in charge have no idea what made the plane go down? They need to start doing their job right.
ReplyDeleteI believe that the airliner was taken down by an outside force. A plane at cruising altitude would not just go down out of nowhere, things like that just don't happen in this day and age, but flying over space like that can be dangerous, and it was probably shot down. I know we can all agree this was an "Enormous tragedy" (Associated Press)
