Malaysia Airlines Flight MH370 Still Missing: New Leads Explored in Plane Disappearance … Possibility Plane Turned Around and Went Down in the Andaman Sea, near Thailand’s Border (Update: Door of Malaysia Flight MH370 Possibly Found)

Amazingly, an entire 777 plane and all aboard are still missing without a trace …

The search continues for missing Malaysia Airlines Flight MH370 that seems to have just vanished. Two hours after the Boeing 777 departed from Kuala Lumpur and was scheduled to land in Beijing, the plane disappeared from radar. The searches so far have yet to find any signs of the missing airline. Malaysian military officials said at a news conference on Sunday that the flight may have changed course and turned back toward Kuala Lumpur. However, the pilot appears to have given no signal to flight control that he was turning around attributing the change of course to indications from radar data. A mystery indeed. Terrorism is still not being ruled out. Sadly, Malaysian Airlines ‘fear the worst’ as missing plane mystery deepens.

Thailand’s navy is shifting its focus in the search for Malaysia Airlines Flight 370 away from the Gulf of Thailand and the South China Sea, Thai Navy Rear Adm. Karn Dee-ubon told CNN on Sunday.The shift came at the request of the Malaysians who are looking into possibilities the plane turned around and possibly went down in the Andaman Sea, near Thailand’s border, Karn said.

Some are comparing the disappearance of Malaysia Airlines Flight MH370 to the Air France flight, an Airbus A330, from Rio de Janeiro to Paris that crashed in the Atlantic midway through the flight without sending a distress signal. In that incident, all 228 aboard were killed.

UPDATE I: 9 nations join hunt for missing Malaysian aircraft.

A total of nine nations have so far joined the multinational efforts in search for a Malaysian Airlines jetliner that went missing Saturday morning on its way to Beijing from Kuala Lumpur with 239 people on board.

Over 40 hours after Flight MH370, a Boeing 777-200ER carrying 227 passengers and 12 crew, vanished over the South China Sea, Thai navy on Sunday night sent a vessel to help find the missing plane, Thai Prime Minister’s Secretary General Suranand Vejjajiva said.

Earlier in the day, Australia announced its air force will send two P-3C aircraft to join the hunt for the missing aircraft.

Currently, a total of 34 aircraft and 40 ships are in hunt for the missing plane, with which the contact was lost along with radar signal at 1:20 a.m. local time on Saturday when it was flying over the Ho Chi Minh air traffic control area in Vietnam, said Director General of Malaysian Department of Civil Aviation Azharuddin Abdul Rahman at a press conference Sunday evening.

Among them are those sent by Malaysia, Singapore, the Philippines, Vietnam and China.

UPDATE II: Missing Malaysia plane possibly ‘disintegrated’ mid-air.

Officials investigating the disappearance of a Malaysian airliner with 239 people on board are narrowing the focus of their inquiries on the possibility that it disintegrated in mid-flight, a senior source said on Sunday.

Malaysia Airlines flight 370 vanished after climbing to a cruising altitude of 35,000 feet between Kuala Lumpur and Beijing in the early hours of Saturday, but search teams have still not been able to make any confirmed discovery of wreckage in seas beneath the plane’s flight path almost 48 hours after it took off.

“The fact that we are unable to find any debris so far appears to indicate that the aircraft is likely to have disintegrated at around 35,000 feet,” said the source, who is involved in the investigations in Malaysia.

UPDATE III: The Pentagon reviewed initial surveillance data from the location where the plane disappeared and did not find evidence of an explosion.

Using a system that looks for flashes around the world, the Pentagon reviewed preliminary surveillance data from the area where the plane disappeared and saw no evidence of an explosion, said an American government official who spoke on the condition of anonymity because the subject matter was classified. A team of aviation experts led by the National Transportation Safety Board was on its way to the area.

UPDATE IV: Door of Malaysia Flight MH370 Possibly Found.

Vietnamese authorities searching waters for the missing Malaysia Airlines Boeing 777 jetliner spotted an object on Sunday that they suspected was one of the plane’s doors, as international intelligence agencies joined the investigation into two passengers who boarded the aircraft with stolen passports.

UPDATE V: Plane-Debris Searchers Find Suspected Aircraft Window Piece.

Vietnamese searchers looking for a missing Malaysian Airline Boeing Co. 777-200 said they found a suspected window or door fragment as efforts to learn the plane’s fate extended to scrutiny of security camera images of two passengers using stolen passports.

Le Van Minh, a Vietnamese coast guard commander, said in a telephone interview today that the fragment is suspected to be part of a plane’s emergency door or window, and that rough seas and darkness were preventing crews from retrieving it. Ships are still searching the area for the piece, which was spotted by helicopter 90 kilometers (56 miles) south of Vietnam’s Tho Chu Island, Minh said.

UPDATE VI: ‘Yellow Object’ Spotted in Sea Wasn’t Life Raft.

Helicopters were scrambled on Monday to a floating “yellow object” that rescue teams believed could be a life raft from the missing Malaysian Airlines plane – but it turned out to be a false alarm.

Pham Quy Tieu, Vietnam’s vice transport minister and deputy head of the its rescue committee, said that a search plane had initially been unable to get close enough to determine what it was.

However, officials later said it was a “moss-covered cap of a cable reel.”

UPDATE VII: ABC News reporting that Oil Slick Samples, Debris Not Connected to Missing Jetliner.

Clues in the disappearance of Malaysia Airlines Flight MH370 remain elusive, with authorities unable to connect debris or oil slick samples to the missing jetliner.

An orange object spotted this morning — originally thought to be a life raft — had nothing to do with the plane wreckage, Vietnam’s National Committee for Search and Rescue told ABC News. The item turned out to be an orange circular side cover of an industrial cable reel. Reports of a different suspicious floating object emerged Sunday, but that object was later ruled out as being connected to the missing jet by Vietnam and Malaysian authorities.

Additionally, oil slick samples found about 100 nautical miles from Malaysia’s east coast of Kelantan, just south of the point of last contact, turned out to have no connection to the missing plane after analysis by Malaysian authorities.
