Day 83 — End of the Bluefin-21 mission

The missing Malaysia Airlines plane is not in the Indian Ocean search zone where acoustic "pings" were detected, search co-ordinators have confirmed.

The acknowledgment came Wednesday as searchers wrapped up the first phase of their effort, having scanned 850 square kilometres of southern Indian Ocean floor without finding any wreckage from the Boeing 777-200. The Bluefin-21 was not able to look at one area in the northernmost ping area because of the depth of the water there.

Authorities now almost universally believe the pings did not come from the onboard data or cockpit voice recorders but instead came from some other man-made source unrelated to the jetliner that disappeared on March 8.

Australia said this week it will negotiate with private companies to conduct the next phase, which will resume in two months, if not later. That phase, which aims to scour about 60,000 square kilometers, probably won't start for at least two months.

This seafloor topography map illustrates jagged plateaus, ridges and other underwater features of a large area underneath the Indian Ocean where search efforts have focused since contact with Malaysia Airlines flight MH370 was lost on March 8.

The new illustration of a 2,000 kilometer by 1,400 kilometer area where the plane might be shows locations on the seafloor corresponding to where acoustic signals from the airplane’s black boxes were reportedly detected at the surface by two vessels in the area. It also shows the two plateaus near where these “pings” were heard.

It points out the deepest point in the area: 7,883 meters (about five miles) underneath the sea in the Wallaby-Zenith Fracture Zone.

Seafloor topography in the Malaysia Airlines flight MH370 search area. Dashed lines approximate the search zone for sonar pings emitted by the flight data recorder and cockpit voice recorder popularly called black boxes. The first sonar contact (black circle) was reportedly made by a Chinese vessel on the east flank of Batavia Plateau (B), where the shallowest point in the area (S) is at an estimated depth of 1637 meters. The next reported sonar contact (red circle) was made by an Australian vessel on the north flank of Zenith Plateau (Z). The deepest point in the area (D) lies in the Wallaby- Zenith Fracture Zone at an estimated depth of 7883 meters. The Wallaby Plateau (W) lies to the east of the Zenith Plateau. The shallowest point in the entire area shown here is on Broken Ridge (BR). Deep Sea Drilling Project (DSDP) site 256 is marked by a gray dot. The inset in the top left shows the area’s location to the west of Australia.

Day 81 — Ping transmissions: Ran out of fuel?

The Malaysian government has today publicly published the final ping transmissions between Malaysia Airlines Flight 370 and an Inmarsat satellite that it was communicating with before it disappeared - so now anyone can investigate what happened to the aircraft.

Based on the same data, the Australian Transport Safety Bureau has also issued a report explaining that the plane most likely descended to its fate after running out of fuel. That's based on calculations of how long it took the plane to descend and modeling of fuel burn for different flight paths. Flight 370's final digital handshake with the satellite didn't coincide with previous regular hourly transmissions. That is likely due to its electrical systems resetting when the plane ran out of fuel, the ATSB summary said. It's still believed the plane crashed into the southern Indian Ocean, though all searches to date have proved fruitless. The conclusion comes as Australia's naval vessel Ocean Shield abandons its search on Wednesday - and a week before authorities open up the hunt to private contractors.

Day 74 — New life born

Wife of MH370 steward gives birth to baby boy. Happiness and radiance were etched on Intan Maizura Othman's face with the arrival of her bundle of joy. But there was still an apparent sadness behind her happiness as her husband, Flight MH370 steward Mohd Hazrin Hasnan was not present to welcome their second child together. Intan Maizura Othman, the wife of Malaysia Airlines Flight MH370 steward Mohd Hazrin Hasnan, has given birth to a baby boy. Muhammad was born at 4pm on Monday, 73 days after Mohd Hazrin went missing together with 238 others on board the flight from Kuala Lumpur to Beijing. Born in Putrajaya Hospital, Muhammad is the second child of Mohd Hazrin and Intan Maizura, 34.

Day 56 — GeoResonance: False trace

Nothing has so far been found in the Bay of Bengal, with regard to a report by an Australian exploration company that it might have located the wreckage of the missing Malaysia Airlines (MAS) MH370 aircraft.

Joint Action Coordination Centre (JACC) Chief Coordinator Angus Houston said: "Currently three Bangladeshi navy ships were scouring the area, with one of the ships equipped with echo sound capability to assist in ensuring a thorough search in that particular area."
“But I will say very quickly that I have the heaviest weight put on all the evidence that is before us, the great work that the world team here in Kuala Lumpur has found, the analysis of the manual handshakes between the aircraft and the satellite."
“And also, the stimulation work has been done to define the area in the southern Indian Ocean. I’m confident the area in the southern (Indian) ocean is the right search area and I’m sure that in time, we will find the aircraft in that area of the Indian Ocean” he said.

More and more seems to be proven that the company GeoResonance pseudo-scientific method is not a real solution. Their "remote sensing" called unspecified technique mostly belong to the notion of quackery. Described with reference to flight MH370 "discovery" is a bad taste advertising, taking advantage of the international attention for the lost Malaysian airplane. Find more evidence here:

Day 55 — MH370-ATC conversation

The Malaysian government has released the preliminary report with audio recordings of the communication between the cockpit and air traffic control on March 8 just before the aircraft lost contact.
