BBC News: Malaysia Airlines Flight MH17 – What we know

Almost 300 people are presumed dead after a Malaysia Airlines jet crashed in eastern Ukraine close to the border with Russia.

Flight MH17 from Amsterdam to Kuala Lumpur was flying over the war-torn region when it disappeared from radar. Some 280 passengers and 15 crew members were on board.

Flight MH17 Crash

What type of plane was it?

The crashed plane was a Boeing 777-200ER, the same model as that of Malaysia Airlines flight MH370, which disappeared while travelling from Kuala Lumpur to Beijing in March.

Aircraft: Boeing 777-200ER

Crew: 15

Passengers: 280

Left Amsterdam: 10:15 GMT

Lost contact: 14:15 GMT at 10,000m (33,000ft)

What happened?

According to Malaysia Airlines, the plane departed Amsterdam’s Schiphol Airport at 10:15 GMT (12:15 local time) on 17 July and lost contact four hours later at 14:15 GMT – 50km from the Russia-Ukraine border. It was due to arrive at Kuala Lumpur International Airport at 22:10 GMT (06:10 local time).

It had been due to enter Russian airspace when contact was lost.

Both the Ukrainian government and pro-Russian rebels who have been fighting in the region have denied shooting it down.

An adviser to the Ukrainian interior minister, Anton Herashchenko, alleges that the plane was hit by a missile fired by a Buk launcher – a Russian-made, medium-range surface-to-air missile system.

Ukraine has accused Russia’s military of supplying advanced missiles to the rebels.

However, separatist leader Alexander Borodai accused the Ukrainian government of downing the airliner itself.

“Apparently, it’s a passenger airliner indeed, truly shot down by the Ukrainian air force,” he told Russia’s state-run Rossiya 24 TV broadcaster.

#MH370: Malaysia Airlines flight lost oxygen, says report

Flight MH370 appeared to be on autopilot across Indian Ocean.

Missing Flight MH370

SYDNEY— Australian authorities said they believe that someone onboard Malaysia Airlines Flight 370 switched on the autopilot system deliberately after the plane turned toward the southern Indian Ocean. They also theorized that all 239 passengers and crew had become unresponsive, possibly after being deprived of oxygen, before the plane ran out of fuel and crashed.

Those were the main reasons the Australian Transport Safety Bureau gave in a report Thursday for setting a massive new search area — the third in as many months for the airliner, which disappeared March 8. The new hunt is slated to restart in August as much as 600 miles south of the previous underwater focus.

Australian Deputy Prime Minister Warren Truss said it was “highly, highly likely” the autopilot was switched on deliberately after the plane had veered off its assigned course from Kuala Lumpur to Beijing.

That is more definitive than investigators have been about human intervention setting up the flight path toward one of the most remote sections of the globe.

The ATSB stressed, however, that its conclusions weren’t backed up by hard evidence, and that Malaysian authorities heading the overall probe may not share their view.

Left unanswered are why Flight 370 deviated sharply from its planned route, or what might have caused the oxygen depletion, known as hypoxia, if that is what occurred.

The Malaysian government and Malaysia Airlines didn’t comment on the report.

The Australians said they justified their assumptions in part because the plane appeared to travel for a long period—about five hours—without any radio communication or dramatic turns or deviations, and presumably without significant altitude changes. They also looked at aircraft maneuvers in previous commercial-plane crashes related to hypoxia.

Satellite radar maps seafloor in hunt for flight MH370

Most detailed map yet of the Indian Ocean floor in the area where Malaysian Airlines flight MH370 is believed to have gone down. The black and red circles indicate where two ships reported receiving possible pings from the flight’s black box. The dashed lines are possible flight paths.

The surface of Mars has been mapped in greater detail than most of Earth’s seafloor. Even though the Red Planet is around 140 million miles away on average (and never closer than 34 million miles), its surface is easier to map because there is no water obscuring it. The lack of good information about ocean floor topography has complicated the search for Malaysian Airlines flight MH370.

Now, two ocean floor mapping experts have gathered all the available data to make a new map of a 2,000 km by 1,400 km (1,240 mile by 870 mile) area in the Indian Ocean near where two boats may have detected pings from the plane’s black box. The map appears today in EOS Transactions, a news publication from the American Geophysical Union.

There are two depth survey tracks made by ships using echo sounders in the area, but these cover only around 5 percent of the search area. And they were done in the ’60s, before GPS navigation was available, so the ships navigated by dead reckoning, using very few set points. The measurements were recorded on paper scrolls, and digitising this type of analogue data is known to introduce errors of 100 meters or more.

So Walter Smith and Karen Marks of NOAA’s Laboratory for Satellite Altimetry filled in the blanks using data gathered from space. Satellites can gauge seafloor topography by measuring the height of the sea surface. This works because an undersea mountain has more mass, and consequently a stronger gravitational pull on the water, which causes a bulge of water to gather above it. Satellites map the sea surface topography by sending radar pulses to the sea surface and measuring how long it takes for them to return.

The resolution of this kind of satellite mapping is only about 20 kilometres (12 miles), but combining this data with ship tracks and information culled from news reports resulted in the best possible map of the area. It shows complicated terrain in the search area that ranges from 1637 metres below sea level (at the top of Batavia Plateau, marked BR on the map) down to 7,883 metres (in the Wallaby-Zenith fracture zone, marked D on the map), a vertical drop of 6,246 metres (almost 4 miles).

Having a better picture of the terrain they are dealing with could help search crews decide which underwater robots to deploy, and could help scientists trying to model where floating debris may have eventually settled.

Malaysia disaster inspires new free global flight tracking

Malaysia disaster inspires new free global flight tracking

In response to the loss of Malaysia Airlines Flight MH370, satellite communications service provider Inmarsat has proposed a free global flight tracking service using its networks, that would be available to all of the world’s longhaul commercial passenger aircraft.

The service has been proposed ahead of a conference being hosted in Montreal today by the International Civil Aviation Organisation (ICAO), which has been initiated by the loss of the aircraft. Inmarsat is offering it to all 11,000 commercial passenger aircraft that are already equipped with an Inmarsat satellite connection — this equates to almost 100 percent of the global longhaul commercial fleet.

As part of the service it will offer enhanced position reporting, sending precise location, speed and altitude data to Inmarsat’s satellite tracking stations every 15 minutes, as well as a “black box in the cloud”. This will be activated by pre-defined trigger events — if a plane deviates unexpectedly off course, for example — and will stream both historic and real-flight data and voice recordings from the cockpit to aviation safety workers.

“Because of the universal nature of existing Inmarsat aviation services, our proposals can be implemented right away on all ocean-going commercial aircraft using equipment that is already installed,” said Rupert Pearce, CEO of Inmarsat, in statement.  Continue reading

Flight MH370 disappearance involved ‘space aliens’, say one in ten Americans

The search continuesThe search continues: Flight officer Rayan Gharazeddine on board a Royal Australian Air Force AP-3C Orion, searches for the missing Malaysia Airlines Flight MH370 in southern Indian Ocean, Australia

One in ten Americans think ‘space aliens’ were involved in the disappearance if the Malaysian Airlines flight MH370, it was revealed today.

A survey found that nine per cent of the people believe ‘space aliens or beings from another dimension were involved’.

Investigators are still continuing their search for the missing plane and the 239 people on board, which vanished from radars on March 8.

The poll by CNN and ORC International found that while most people in the U.S. believe the search for MH370 should continue, half believe authorities are searching in the wrong place.

Findings also showed that the vast majority (79 per cent) believe there are no survivors.
