Search is still on for the wreckage and black box, with several spottings reported

Today in Kuala Lumpur, Malaysia, more than two weeks of mystery and searching came to a close. Malaysian Prime Minister Najib Razak announced that compelling evidence existed that missing flight MH370 had crashed into the Pacific and that the 239 people on board (227 passengers and 12 crew members) had perished.
I. At Last, the Answer to One Big Question
The story was intriguing, in part, because the aircraft involved -- the Boeing Comp.'s (BA) Boeing 777 -- had previously owned a near perfect track record.  The Boeing 777 had previously only seen 4 incidents that damaged the hull of a plane -- two of these incidents involved overrunning the runway.  Only the most recent incident -- the July 2013 crash of an Asiana Airlines passenger craft at San Francisco International Airport -- led to any fatalities.  That incident, still under investigation, led to the deaths of 3 of the craft's 307 passengers.
Flying on a Boeing 777 from a historic standpoint would be considered a pretty safe travel plan from a statistical standpoint.  Unfortunately, the Malaysian Airlines (Malaysia Airlines System Bhd (MK:MAS)) flight would buck that track record, becoming the deadliest crash in the aircraft's history.

Flight MH370 took off from Malaysia's capital and most populous city, Kuala Lumpur, on March 8.  Scheduled for a relatively short flight to Beijing, the aircraft never arrived.  It veered sharply eastward, travelling over Thailand, while reportedly making wild changes in altitude.
From there the aircraft seemingly vanished leaving everyone wondering where it went.  The two leading theories were that it flew south, which would place it in somewhere off the west coast of Australia, or north, which would put it somewhere in the northern Indian Ocean, off the east coast of India.

The U.S., China, UK, India, Australia, and various European nations set aside their political differences for the moment and embarked on an ambitious international hunt to find the wreck of MH370.
Critical clues to the craft's final destination came via UK satellite company Inmarsat plc (LON:ISAT), which built semi-autonomous location services into every Boeing 777.  Working in unison with the UK's Air Accidents Investigation Branch (AAIB), the data from responses to "pings" -- data requests to the aircrafts computer -- eventually allowed the crash site to be narrowed to a patch of ocean 1,500 miles (2,500km) off the southwest coast of Australia.
According to BBC News, Inmarsat's engineers worked all through this last weekend to try a never-before-used technique to analyze the data in the face of lacking data to further triangulate the craft's trajectory by traditional means.

The new technique reportedly compared data pings from past aircraft traveling over both locations in order to zero in on where exactly the craft was.  The tactic was, by all accounts, a remarkable and brilliant success.  With a refined location searchers from China and Malaysia were reportedly able to spot debris, likely the remains of MH370.
II. Debris Sighted
In his statement the Malaysian PM said it was "beyond reasonable doubt" that the plane had crashed.  He went on to state:

[We] have concluded that MH370 flew along the southern corridor, and that its last position was in the middle of the Indian Ocean, west of Perth.  This is a remote location, far from any possible landing sites. It is therefore with deep sadness and regret that I must inform you that, according to this new data, flight MH370 ended in the southern Indian Ocean.

As of late yesterday the actual crash site had yet to be located definitively.  French satellite images showed what appeared to be belts (possibly seatbelts from destroyed craft, a wooden pallet, and other items that might be buoyant pieces of a wrecked Boeing 777.  China, meanwhile, spotted a 72 ft. by 43 ft. sunken object that was roughly in the same region via satellite.
But investigators have to line those reports up with an actual location in the remote stretch of sea, something they were unable to do on Sunday.

While it's perhaps dangerous for family members of the passengers to hold too much hope that their family members survived the crash, some have held on to hope that some passengers might have been able to deploy a life raft and survive.  Roughly two-thirds of the passengers were Chinese.

China's Foreign ministry spokesman, Hong Lei, announced a fresh finding of possible debris at a press conference, stating:

We are still racing against time.  As long as there is a glimmer of hope, our search efforts will carry on.

The race has high stakes, as whatever debris is floating could easily float miles away in hours, driven by ocean currents.  On Monday, China's two search planes in the region spotted two large objects and several smaller ones scattered across several kilometers.  According to Mr. Lei, one of these objects was white and rectangular.  A second flyover by a US Navy P8 Poseidon, a large Boeing military aircraft, was unable to spot the objects the Chinese planes had seen.

The latest hopes come courtesy of a Lockheed Martin Corp. (LMT) P3 Orion deployed by Australia, which spotted two objects -- "the first grey or green and circular, the second orange and rectangular", according to a news report by The Guardian.
China has diverted an additional six warships to help scour the region.

Reactions from family members have been varied.  In Malaysia, there seemed to be a grim acceptance among the family members and loved ones of passengers, most of whom were Muslim.  Selamat Omar, the father of a 29-year-old junior aviation engineer onboard the flight, told the Associated Press:
We accept the news of the tragedy. It is fate.
In China, the Malaysian PM's statements were greeted with fresh fury, however.  A statement read to the media from the family members and loved ones of the Chinese passengers, stated:

[The Malaysian government] misled, delayed the research and rescue, wasted a lot of man power, and material resources and we lost the most valuable rescue opportunity. If our 154 relatives lost their lives because of it, Malaysia Airlines, the Malaysian government, and the Malaysian military are [their] killers.

Even if debris can be located, it is unclear whether they will be able to solve the biggest mystery -- the events that doomed the flight.  Some have speculated that the airline was hijacked.  Theories towards that end have ranged from speculation that perhaps one of the pilots incapacitated the other and decided in order to carry out a suicide flight, or that one or more terrorists were hidden among the flight's passengers and hijacked the craft.

On the other hand, it's possible that the craft suffered some sort of catastrophic damage that may have left the pilots struggling for control.  The craft was carrying 200 kg of flammable lithium-ion batteries.  While that backup power system was reportedly inspected and deemed safe, Boeing has suffered past issues with battery fires with a similar pack used in the newer Boeing 787 Dreamliner aircraft, which forced it to commit to a series of redesigns.  
Some have suggested that the plane's autopilot systems could have kicked in and kept it flying at cruising altitude for several hours as a "zombie plane" if some catastrophic failure incapacitated and/or killed the passengers and crew.
The plane's black box could yield vital clues as to what happened.  The U.S. Pacific Command has a vessel en route with a black box detector that is towed behind the craft.  If the backup power is intact and the wreckage is at 6,100 metres (20,000 ft.) the detector may be able to locate signals in the wreckage region, and dispatch manned submarines and/or autonomous deep-water vehicles in a recovery attempt.

Autopilot could not maneuver the plane at 45000 feet. Nor can it makes the plane climbed to 23000 feet after dropping to about 12000 feet
This sounds to me like the exact expected behavior of a stable plane that is trimmed for a speed higher than it's current cruise speed and with no one (including auto-pilot and throttle) at the controls.

The pilot sets the speed he wants the plane to go, the plane automatically (via aerodynamics not electronics) climbs or descends to maintain that speed. If the trim setting were improperly set significantly lower than cruise speed for the current throttle setting, the plane will climb and continue climbing until it stalls out (which would be at the very top of the the planes operational ceiling, for a 777 about 43,000 ft). Once it stalls it'll pitch forward and descend rapidly. If the air speed climbs fast enough, the same trim settings will eventually pull the plane out of the dive and start it climbing again.

here's what solandri posted:
Phugoid oscillations for larger aircraft with improper trim are typically less than a minute to a few minutes. On United 232, it was about 40-60 seconds. That was a 55 meter DC-10, not much different from a 61 meter 777.

It's highly unlikely that the reported altitude variations (~20,000 feet) could've been caused by a phugoid. At most you'd expect to see a variation of a few thousand feet.

Besides, the wild altitude changes isn't the only thing that makes me think it's unlikely to be a zombie plane, there's also the course correction. Here's what MozeeToby posted about that
The later course changes are harder to understand but it's possible that the plane was flying dead stick with the auto-pilot off. Small instabilities can cause heading changes before the fly by wire safety systems override and level the plane out again (doesn't happen until the plane is rolling 30 degrees or more to one side). Of course, it's also possible that the flight crew was suffering from hypoxia (either from smoke inhalation or decompression) and was simply not making good decisions by that point.

That explanation can explain if it there were only one course correction. But there are at least three course correction after the plane turn back to Malaysia ( ) over the course of several hours (more than 5). You know what they say ( ) Once is an accident. Twice is coincidence. Three times is an enemy action
