Is it possible a flight with 239 people suddenly disappears from sky? Airlines not ready to accept the crash. Plane cant fly more than 3 days.

One of the reputed airline. Plane is not flying nor on earth. What r other possibilities?

And is it safe to trust that airlines?

If it crashed at the sea it is possible that it lies submerged intact on the sea bed which could be too deep for the rescuers to detect anything.

Malaysia is becoming the laughing stock of the whole world! First five passengers checked luggage reported and now the police chief deny that. And now they comes another contradiction on plane direction!...Can the Malaysian government make up their freakin minds and actually provide some real help by letting real professionals figure out what happened?OuchConfused

Are they trying to hide something?

MH370 - what happened...

Summary: It's plausible that a fuselage section near the SATCOM antenna adapter failed, disabling satellite based -  GPS, ACARS, and ADS-B/C - communications, and leading to a slow decompression that left all occupants unconscious. If such decompression left the aircraft intact, then the autopilot would have flown the planned route or otherwise maintained its heading/altitude until fuel exhaustion. 
slow decompression (e.g. from a golfball-sized hole) would have gradually impaired and confused the pilots before cabin altitude (pressure) warnings sounded. 
Chain of events:
  • Likely fuselage failure near SATCOM antenna adapter, disabling some or all of GPS, ACARS, ADS-B, and ADS-C antennas and systems. 
  • Thus, only primary radars would detect the plane. Primary radar range is usually less than 100nm, and is generally ineffective at high altitudes.
If the decompression was slow enough, it's possible the pilots did not realize to put on oxygen masks until it was too late. (See Helios 522)With incapacitated pilots, the 777 could continue to fly on Autopilot - programmed to maintain cruise altitude and follow the programmed route. Using the Inertial Reference System (gyroscope based), the plane could navigate without needing GPS. 
Other thoughts:
  • The plane was equipped with cellular communication hardware, supplied by AeroMobile, to provide GSM services via satellite. However this is an aftermarket product; it's not connected through SATCOM (as far as I know). 
  • This explains why 19 families signed a statement  alleging they were able to call the MH370 passengers and get their phones to ring, but with no response.
  • When Malaysian Airlines tried to call the phone numbers a day later, the phones did not ring. By this time, fuel would have been exhausted.
Note:  777 Passenger Oxygen masks do not deploy until cabin altitude reaches 13,500. Passengers were likely already unconscious by then, if it was a slow decompression. Also remember that this flight was a red-eye, most passengers would be trying to sleep, masking alarming effects of oxygen deprivation. No confirmed debris has been found anywhere near the search area, consistent with the plane having flown for hours after it lost radar contact.
Conclusion:
This was likely not an "explosive decompression" or "inflight disintegration." This was likely a slow decompression that gradually deprived all crew/passengers of oxygen, leaving the autopilot to continue along the route autonomously.
The aircraft may be at the floor of the East China Sea, Sea of Japan, or the Pacific Ocean thousands of miles northeast from the current search zone.  [UPDATE: Basically, it could be "anywhere", and we need to use any available radar records to help figure it out. It could have turned in any direction and continued on for hours. This is where the Vietnamese/Malaysia civilian and military radars will help.]
Recommendations:
Investigators should obtain data logs from primary radars throughout mainland China that would have been along the planned route. They may be the best clue as to the trajectory of the aircraft.
Investigators should obtain all passengers' cell phone log and location data. The timing of the last successful cellular connection (ring/SMS/data-packet) can predict how long the plane was in the air. iPhone/iOS location (GPS) datamay be available from Apple if subpoenaed. Android location data may be available from Google. 
 Add a secondary search space to include a 300nm+ radius around Beijing, focusing on surrounding bodies of water. Using planned routing trajectory, known autopilot logics, fuel quantities, and weather patterns, it may be possible to define a smaller 50nm * 50nm search space. Consider running the above scenario in MH's 777-200ER full flight simulator.  
 Boeing should provide expertise about the SATCOM antenna schematics and autopilot/navigation logic, so as to help plot this second search space.

Lets summarize possibilites. Basically it was there on radar and then it was gone.
 
1- Blown up - terrorism
2- Blown up - mechanical
 
where is the debri?
 
3- Failed and crashed into the sea then and there
4- Failed and went west and then crashed
 
where is the distress signal?
 
5- Hijacked
 
where is the contact, demand
 
6- It was shot down by military thinking it was intrusion
 
why hiding
 
7- One person in a newspaper suggested it might have gone up instead of going into sea
 
Right now I am going with option 3/4
 
Edit: I know the country and it is well developed and modern and advance. They are dealing it well by involving others. They had almost perfect record in aviation. This news was tragic but more so because I know the country and people. I am very confident they will sort it out in good way.

Debris can be easily lost at sea and not detectable.

 

Planes can disintegrate or crash suddenly without time for distress signal. Slow decompression due to a small leak can cause the crew to go unconscious and unable to send distress signal.

 

For some reason the plan suddenly crashed at sea (either disintegrated or intact) and the debris is lost at sea (either disintegrated or intact).

 

People should stop fussing and freaking about flying. Plane crashes make the headlines but are a rare occurrence considering the volume of flights. This is even a rarest of the rare. You are several times more likely to die in a road accident.

 

I wouldn't point fingers at Malaysia. I'm sure even FAA would screw up a few times before getting their story straight. After all, it indeed is rocket science (albeit a lesser form).
