Interesting hypothesis that would square with this: http://www.antipope.org/charlie/blog-static/2014/03/a-hypoth...

I'm curious why there isn't redundancy in oxygen supplies? Under such conditions would the crew at least be aware enough to know the oxygen tank they are drawing from is faulty and that they need to switch to the backup tank.

This begs the question: why on earth is it even possible to turn off a transponder mid-flight on a commercial plane carrying hundreds of human beings? I also don't understand why, if we can send bursts of engine data every 30 minutes from the middle of the ocean, we can't send a GPS location every couple of minutes. Maybe even throw some GPS data in with the engine data - at least we would know where it was within a…

The simple answer is you have dozens of planes on the ground at airports, which you don't want to appear on all the radars. Yes, a technological fix would be trivial, but those systems were designed decades ago, when being a pilot was quite prestigious and well paid. The thought of a rogue pilot never occurred, I guess. Locaiton data is sent by the ACARS system, which was apparently turned off.

Why not have two types of transponders, one that is always on like lojack for planes and one that is only on for planes in the air. As long as there is some information being sent that determines what kind of signal it is, it should be trivial to have a radar system that filters out those only broadcasting their always on system.

You don't need a transponder to show up on radar, it just makes it a lot easier. Radar operators have a hard job telling a plane from clouds or echos. A transponder makes that job a lot, lot easier. However, if you have a good radar system, you can happily track the contact without a transponder. In fact this happens all the time, I had a very nice chap at Farnbourgh West LARS (Low Altitude Radar Service) do this for…

This is my issue - an aeroplane disappearing from SSR and not making contact on the next frequency = sends up someone to have a look. Perhaps Malaysia's air force isn't as trigger-happy as here in England?

P.S. Never thought I'd see Farnborough West mentioned on HN! Hello fellow South Eastern pilot.

Why no one is paying attention to the fact that the plane was flying over South China see which China is trying to claim for itself. Could it be the case that China by mistake shot the plane down ?

Impossible. The consequence of hiding the truth is an international shame. And do you really think any country launching a missile can go unnoticed? You know that area is under dispute and nearby countries are claiming ownership, meaning they are actively monitoring all military actions. There are satellites watching that area too. No. No. And why China? I think this is more of an anti-China/China conspiracy. You got…

Some people do share to share my doubts about China http://www.wnd.com/2014/03/china-intercepted-missing-malaysi...

Is it possible to hack a transponder and make it appear to ATS that a plane is a legitimate craft? Would it be possible to have someone on the ground act as "ATC" and pass off the plane to an unsuspecting ACT so it can enter another countries air space?
