Malaysia Airlines jet mystery: 'plane door' not recovered

A Vietnamese official says searchers on ships worked throughout the night but could not find a rectangle object spotted Sunday afternoon that was thought to be one of the doors of a missing Boeing 777.

Doan Huu Gia, the chief of search and rescue coordination centre, said Monday that six planes and seven ships from Vietnam were searching for the object but nothing had been found.

Malaysia Airlines Flight MH370 went missing early Saturday morning on a flight from Kuala Lumpur to Beijing with 239 people on board.

The plane lost contact with ground controllers somewhere between Malaysia and Vietnam, and searchers in a low-flying plane spotted an object that appeared to be one of the plane's doors, the state-run Thanh Nien newspaper said.

Troubling questions still remain about how two passengers managed to board the ill-fated aircraft using stolen passports.

Authorities were checking on the identities of the two passengers who boarded the plane with the stolen documents. On Saturday, the foreign ministries in Italy and Austria said the names of two citizens listed on the flight's manifest matched the names on two passports reported stolen in Thailand.

"I can confirm that we have the visuals of these two people on CCTV," Malaysian Transport Minister Hishammuddin Hussein said at a news conference late Sunday, adding that the footage was being examined. "We have intelligence agencies, both local and international, on board."

Stolen passports

Interpol confirmed it knew about the stolen passports but said no authorities checked its vast databases on stolen documents before the Boeing jetliner departed Saturday from Kuala Lumpur en route to Beijing with 239 people on board.

Warning "only a handful of countries" routinely make such checks, Interpol secretary general Ronald Noble chided authorities for "waiting for a tragedy to put prudent security measures in place at borders and boarding gates."

The thefts of the two passports — one belonging to Austrian Christian Kozel and the other to Luigi Maraldi of Italy — were entered into Interpol's database after they were stolen in Thailand in 2012 and last year, the police body said. But no authorities in Malaysia or elsewhere checked the passports against the database of 40 million stolen or lost travel documents before the Malaysian Airlines plane took off.

In a forceful statement, the Interpol chief, who has called passport fraud one of the world's greatest threats, said he hoped "that governments and airlines worldwide will learn from the tragedy."

"Now, we have a real case where the world is speculating whether the stolen passport holders were terrorists," Noble said. "Interpol is asking why only a handful of countries worldwide are taking care to make sure that persons possessing stolen passports are not boarding international flights."

A telephone operator on a China-based KLM hotline confirmed Sunday that passengers named Maraldi and Kozel had been booked on one-way tickets on the same KLM flight, flying from Beijing to Amsterdam on Saturday. Maraldi was to fly on to Copenhagen, Denmark, and Kozel to Frankfurt, Germany.

She said the pair booked the tickets through China Southern Airlines, but she had no information on where they bought them.

Visa bypass

As holders of EU passports with onward flights to Europe, the passengers would not have needed visas for China.

Interpol said it and national investigators were working to determine the true identities of those who used the stolen passports to board the Malaysia Airlines flight. White House Deputy National Security Adviser Tony Blinken said the U.S. was looking into the stolen passports, but that investigators had reached no conclusions.

The missing jetliner apparently fell from the sky at cruising altitude in fine weather, and the pilots were either unable or had no time to send a distress signal — unusual circumstances under which a modern jetliner operated by a professional airline would crash.

Gordon Dupont, a former accident investigator for the Transportation Safety Board of Canada, said it is unlikely the slicks were connected to the plane's disappearance.

"When an aircraft that size hits the water, there is going to be all kinds of stuff floating in the water," he told CBC News.

"Unless they find some debris, I would not think it's from the aircraft. And I'm not sure why it would be two separate large slicks. It would normally be one slick."

In addition to the plane's sudden disappearance, which experts said was consistent with a possible onboard explosion, the stolen passports strengthened concerns about terrorism as a possible cause. Al-Qaeda militants have used similar tactics to try to disguise their identities.

Still, other possible causes included a catastrophic failure of the plane's engines, extreme turbulence, or pilot error or even suicide. Establishing what happened with any certainty will need data from flight recorders and a detailed examination of any debris, something that will take months if not years.

Malaysia's air force chief, Rodzali Daud, said radar indicated that before it disappeared, the plane may have turned back, but there were no further details on which direction it went or how far it veered off course.

"We are trying to make sense of this," Daud said at a news conference. "The military radar indicated that the aircraft may have made a turn back, and in some parts this was corroborated by civilian radar."

Malaysia Airlines Chief Executive Ahmad Jauhari Yahya said pilots are supposed to inform the airline and traffic control authorities if the plane does a U-turn. "From what we have, there was no such distress signal or distress call per se, so we are equally puzzled," he said.

A total of 34 aircraft and 40 ships from Vietnam, Malaysia, Thailand, Australia, Singapore, Indonesia, China and the United States were deployed to the area where ground controllers lost contact with the plane, the maritime border between Malaysia and Vietnam.

Families prepare for the worst

Of the 227 passengers and 12 crew members on board, two-thirds were Chinese, while the rest were from elsewhere in Asia, Europe and North America, including three Americans.

Two Canadians were named in the flight manifest, released by the airline Saturday. They have been identified as Muktesh Mukherjee, 42, and, Xiaomo Bai, 37. The married couple had been on vacation in Vietnam. The airline told CBC News that family members of the two Canadians had been informed.

Family members of Philip Wood, a 50-year-old IBM executive who was on board the plane, said they saw him a week ago when he visited them in Texas after relocating to Kuala Lumpur from Beijing, where he had worked for two years.

"There is a shock, a very surreal moment in your life," said Wood's brother, James Wood. "With a situation like this, when a plane just disappears … it leaves you with a lot of questions."

The other two Americans were identified on the passenger manifest as 4-year-old Nicole Meng and 2-year-old Yan Zhang. It was not known with whom they were travelling.

After more than 30 hours without contact with the aircraft, Malaysia Airlines told family members they should "prepare themselves for the worst," Hugh Dunleavy, the commercial director for the airline, told reporters.

A team of American experts was en route to Asia to be ready to assist in the investigation into the crash. The team includes accident investigators from the National Transportation Safety Board, as well as technical experts from the Federal Aviation Administration and Boeing, the safety board said in a statement.

Malaysia Airlines has a good safety record, as does the 777, which had not had a fatal crash in its 19-year history until an Asiana Airlines plane crashed last July in San Francisco, killing three passengers, all Chinese teenagers.
