画像 昼前、ラジオをかけていたら「クアラルンプール発北京行きのマレーシア航空機が行方不明」のニュース。CNNで詳しい情報を確認すると、行方不明機はMH370便のボーイング777-200であることがわかる。離陸した飛行機が「消息不明」となるということは、墜落した可能性が極めて高い。しかも巡航中、人の目の触れにくい山中や海上に墜落。最悪の事態が頭に浮かぶ。B777の全損事故は過去に2度あるが、いずれも着陸直前で乗客乗員の多くは生還した。巡航中の墜落全損となれば初のケースで、世界中が衝撃を受けることになるだろうな、と思った。

 行方不明となっているMH370便は、クアラルンプール発を8日午前0時35分に出発し、同6時30分に北京に到着するスケジュールだった。飛行距離は約3700km。午前2時40分にマレーシアのスバン管制センター(Subang Air Traffic)と交信を断ち、その後捜索中とのこと。搭載燃料は7.5時間分というから、マレーシア時間午前8時(日本時間午前9時)までに不時着などが確認されなければ、墜落が確定ということになる。

 墜落が、連絡を絶った午前2時40分付近だとすれば、離陸から約2時間後。地図から見るに、ベトナムの山中か海上を飛行していたはずで、捜索は難航するだろうな、と思った。

画像 MH370はどこへ行った? Flightrader24のPLAYBACK機能で、クアラルンプール空港出発からの航跡を再現してみる。時刻を7日の1640UTC(現地時刻 8日0時40分)にセットすると、1分ほどでMH370を示す機体マーク(MAS370と表示される)が現れた。機体番号9MMRO。北西方向に離陸した後すぐに右旋回し、ほぼ北に進路をとりつつマレー半島を横断し、約25分で洋上へ。南シナ海を北北東へ進んでベトナム最南端のカマウ岬を目指すが、タイランド湾を3分の1ほど進んだところで、突然航跡が消えてしまった。時刻は1716UTCを少し過ぎたところ。1716は現地時刻 1時16分。消息を絶ったとされる2時40分よりも1時間24分も前だ。どういうこと?

 ふと思ってロイターの記事を見ると「1721GMTの定時位置通報が行われなかった」ということが、ベトナム民間航空局発の情報として出ている。GMTとUTCはイコール(厳密には100年で十数秒の誤差があるらしいが)。つまり、1716すぎにFlightrader24の画面から航跡が消えた事実と、ぴったり符合する。1716時点の位置は北緯6.3度東経103度、飛行方位25度(北北東)。高度35,000ft(約10500m)、対気速度472ノット(約870km)、垂直速度0ft(水平飛行中)。一切の異常が数値からは見られない。ここから5分以内に墜落とは、いったい何があったのだろう? 機体異常やハイジャックなどの連絡が一切なかった(伝えられていない)ところを見ると、爆弾や圧力隔壁の損傷などによる一瞬の空中分解か? 考えられる可能性はいくつかあるが、現時点ではなんとも言えまい。

 墜落地点は、マレーシアのコタバルとベトナムのカマウ岬を結ぶ線の中間付近の海上の可能性が高い。高度1万メートルから真っ逆さまに落ちたとなれば、機体はバラバラになって水没。捜索や遺体の収容、原因究明のためのブラックボックス回収は難航することになるだろう。


Search intensifies for Malaysian airliner and 239 people, rescue ships head to sea
By Tom Watkins and Chelsea J. Carter, CNN
March 8, 2014 -- Updated 0519 GMT (1319 HKT)
(CNN) -- (CNN) -- Malaysia Airlines flight carrying 239 people from Kuala Lumpur to Beijing disappeared Saturday after air traffic controllers lost contact with the plane, the airline said.
"At the moment we have no idea where this aircraft is right now," Malaysia Airlines Vice President of Operations Control Fuad Sharuji said on CNN's "AC360."
Subang Air Traffic Control lost contact with Flight MH370 at about 2:40 a.m. local time (1:40 p.m. ET Friday), Sharuji said.

Quest: Odd to lose contact while cruising Plane loses contact with airline
"We tried to call this aircraft through various means," he said. The airline checked reports that the jet had landed in several places, but determined that none of the reports was true, he said.
The Boeing 777-200 departed Kuala Lumpur International Airport at 12:41 a.m. and was expected to land in Beijing at 6:30 a.m., a 2,300-mile (3,700 kilometer) trip. It was carrying 227 passengers, two of them infants, and 12 crew members, the airline said.
At the time of its disappearance, the plane was carrying about 7.5 hours of fuel, Sharuji said.
The passengers are of 13 nationalities, the airline said. They were from China and Taiwan (154), Malaysia (38), Indonesia (12), Australia (7), France (3), United States (4), New Zealand (2), Ukraine (2), Canada (2), Russia (1), Italy (1), Netherlands (1), Austria (1).
One infant from the United States and another from China were included in the tally.
By CNN's math, that adds up to 228 passengers, one more than the total cited by the airline. There was no immediate explanation offered.
"Malaysia Airlines is currently working with the authorities who have activated their Search and Rescue team to locate the aircraft," the statement said. The public can call +603 7884 1234 for further information.
"We deeply regret that we have lost all contacts" with the jet, said CEO Ahmad Juahari Yahya in a statement.
Efforts to contact the plane in the hours after it disappeared were fruitless. China deployed two rescue ships in the South China Sea to begin a search, state-run broadcaster CCTV said.
Family and friends of those missing on the flight gathered at a hotel complex in the Lido district of Beijing. People were being led in through a throng of reporters, with those friends and relatives saying nothing to the media.
One woman had her hand to her face. As the door opened, a man inside looked anxious as he talked on a cell phone.
The airline's website said the flight was piloted by Cap. Zaharie Ahmad Shah, 53, a Malaysian. He has 18,365 total flying hours and joined Malaysia Airlines in 1981, the website said. The first officer is Fariq Ab.Hamid, 27, a Malaysian with a total of 2,763 flying hours. He joined Malaysia Airlines in 2007.
The airline said in a statement that its representatives were contacting the relatives of those aboard. "Focus of the airline is to work with the emergency responders and authorities and mobilize its full support," it said.
China's state-run Xinhua News Agency said the flight lost contact and its radar signal as it was flying over the Ho Chi Minh air traffic control area in Vietnam.
China's embassy in Malaysia formed an emergency team headed by the Chinese ambassador to deal with the incident, it said.
"We're closely monitoring reports on Malaysia flight MH370," Boeing said in a tweet. "Our thoughts are with everyone on board."
"It doesn't sound very good," retired American Airlines Capt. Jim Tilmon told CNN's "AC360." He noted that the route is mostly overland, which means that there would be plenty of antennae, radar and radios to contact the plane.
"I've been trying to come up with every scenario that I could just to explain this away, but I haven't been very successful."
He said the plane is "about as sophisticated as any commercial airplane could possibly be," with an excellent safety record.
"The lack of communications suggests to me that something most unfortunate has happened," said Mary Schiavo, former inspector general of the U.S. Department of Transportation, in an interview with CNN International. "But that, of course, does not mean that there are not many persons that need to be rescued and secured. There's still a very urgent need to find that plane and to render aid."
There is one recent blemish for the Boeing jet: An Asiana Airlines Boeing 777 carrying 291 passengers struck a seawall at San Francisco International Airport in July 2013, killing three people and wounding dozens more.
Malaysia Airlines operates in Southeast Asia, East Asia, South Asia, the Middle East and on the route between Europe and Australasia.
It has 15 of the Boeing 777-200 planes in its fleet, CNN's Richard Quest reported.
Part of the company is in the private sector, but the government owns most of it.
Malayan Airways Limited began flying in 1937 as an air service between Penang and Singapore. A decade later, it began flying commercially as the national airline.
In 1963, when Malaysia was formed, the airline was renamed Malaysian Airlines Limited.
Within 20 years, it had grown from a single aircraft operator into a company with 2,400 employees and a fleet operator.

Malaysia Airlines loses contact with plane carrying 239 people
(Reuters) - A Malaysia Airlines flight carrying 227 passengers and 12 crew from Kuala Lumpur to Beijing lost contact with air traffic controllers early on Saturday, the airline said in a statement, the plane likely missing in Vietnamese airspace.
Flight MH370, operating a Boeing B777-200 aircraft left Kuala Lumpur at 12.21 a.m. (11.21 a.m. ET Friday) and had been expected to land in the Chinese capital at 6.30 a.m. (5.30 p.m. ET) the same day.
"We deeply regret that we have lost all contacts with flight MH370," Malaysia Airlines Chief Executive Ahmad Jauhari Yahya said in a statement.
"Malaysia Airlines is currently working with the authorities who have activated their search-and-rescue teams to locate the aircraft," it said.
An official at the Civil Aviation Authority of Vietnam (CAAV) said the plane had failed to check in as scheduled at 1721 GMT (12.21 p.m. ET) while it was flying over the sea between Malaysia and Ho Chi Minh city.
"Its code didn't appear in our system," Bui Van Vo, the CAAV's flight control department manager, told Reuters by telephone.
China's official Xinhua news agency also quoted the Civil Aviation Administration of China (CAAC) as saying the flight lost contact while flying through Vietnamese airspace.
The CAAC said 158 Chinese nationals were on board the plane. China's aviation regulators said they had not received any signals from the plane and that there had been no reports of any aircraft crashing in Chinese waters.
"We are extremely worried," Chinese Foreign Minister Wang Yi told reporters in Beijing. "We are doing all we can to get details. The news is very disturbing. We hope everyone on the plane is safe."
Chinese state TV also said there had not been any immediate reports of a plane crashing in Chinese waters.
If the plane is found to have crashed, the loss would mark the second fatal accident involving a Boeing 777 in less than a year, after an unblemished safety record since the jet entered service in 1995.
Last summer, an Asiana Airlines Boeing 777 crash-landed in San Francisco, killing three passengers.
Boeing said it was aware of reports that the Malaysia Airlines plane was missing and was monitoring the situation but had no further comment.
Malaysia Airlines said it was contacting the families of those on board flight MH370 and had set up support facilities for those affected.
"Focus of the airline is to work with the emergency responders and authorities and mobilize its full support," the airline statement said.
"Our thoughts and prayers are with all affected passengers and crew and their family members."
Distressed family members of those on board had also begun gathering at Beijing airport on Saturday.
Chang Ken Fei, a Malaysian waiting at Beijing airport for friends to arrive, said: "I got here at seven (a.m.). At first I thought the plane was just delayed as normal, so I came a bit later, I've just been waiting and waiting.
"I asked them what was going on but they just tell us 'we don't know'."
