Flight MH370: Malaysian radar, passenger phone contact, high-altitude hypoxia

While that might seem far-fetched, it does raise an interesting question about why they got the handoff transmission so completely wrong in the first transcript. The transmissions from the plane were the pilot's negotiations with authorities who (wrongly) called his bluff and now want to cover up any trace of their complicity. It sort of fits in with my gut feeling that the Malaysian government doesn't (and didn't) ever want to find that planes wreckage and the revelation that they didn't believe the pilot would actually kill himself and all the passengers. Plus, it provides a pretty strong motive for what seemed until now to be a crime without a motive. The problem I see is that even if the wreckage is found, if there was back-and-forth "hostage negotiation" taking place, it got wiped out by the CVR recording over old material every two hours. -- Bobby G. |

More importantly, though, he said that although that plane *could* land on a very short runway, not very many of the alternates proposed as landing sites would actually accommodate that model of plane without collapsing the landing gear. All airstrips, apparently, have a rating that indicates how much weight they can support. That's true and one of the big problems with the theory that some terrorists flew it off to some remote landing strip in the desert. It has to be long enough and strong enough to land the plane. But it's a major problem for the fire theory, because Kota Bahru had a suitable runway, they passed right by it 140 miles before contact with ATC was lost and it was the logical place to divert to for a sudden extreme emergency. This guy, an ex-SEAL, went on to postulate that it *was* the pilot who was so unhappy with the jailing of his friend that he took the plane hostage and radioed a demand for his friend's release to authorities, threatening to crash the plane if they didn't. While that might seem far-fetched, it does raise an interesting question about why they got the handoff transmission so completely wrong in the first transcript. The transmissions from the plane were the pilot's negotiations with authorities who (wrongly) called his bluff and now want to cover up any trace of their complicity. I'd put the odds of that very low, because it doesn't fit very well. The part of the communication they got wrong was just the last few words of MH370 saying goodbye to Malaysian ATC. I don't see how them getting that right or wrong has anything to do with with some negotiation theory. In fact, the negotiation would have to have come after that point, not before it. And logically, if someone was demanding a ransom, why would the plane be flying off to Australia? A pilot demanding a ransom would know that it would take hours for anyone to be able to act on such a demand, one way of the other. The plane would most likely be circling, or remain somewhere in the Malaysi area, not be making a route to Autralia. The other huge problem with this crazy idea is how in the world do you land the plane, deliver the passengers, collect the ransom and get away with it? It sort of fits in with my gut feeling that the Malaysian government doesn't (and didn't) ever want to find that planes wreckage and the revelation that they didn't believe the pilot would actually kill himself and all the passengers. Plus, it provides a pretty strong motive for what seemed until now to be a crime without a motive. That theory makes sense to you? You're going to hijack a plane with 250 people on it, hold them for ransom, collect it somehow and just live happily ever after? That makes sense compared to say just a suicidal pilot? The problem I see is that even if the wreckage is found, if there was back-and-forth "hostage negotiation" taking place, it got wiped out by the CVR recording over old material every two hours. There have been leaks all over the place on this thing. It would really be something for this extended negotiation scene to have played out and not one person has leaked it to the media. Last I heard, they were 80%+ done with the search area where the pings were heard. And they said if they didn't find anything in the remaining area, they were going to bring in more powerful sonar eqpt. that could penetrate deeper into the floor. I still haven't heard anything about what the bottom is like there. There was some speculation that it could be many feet of silt into which the debris could sink. I wonder if anyone thought of the idea of finding out what the bottom is like? Maybe dropping a couple of test objects of different weights/densities, then using the existing sonar to see if they show up, how deep into the floor they go, etc. If the test objects are easily found, then it would pretty much tell you that it's not a problem of the debris having sunk into 20 ft of silt. |

So that gives us another little clue to the puzzle and strongly implies a very quick terminal event. It also suggests that airlines need to rethink their technology quite a bit because when these events occur, millions of dollars are wasted in huge search efforts. I am not sure how the MH370 crash will percolate through the system, but I hope that at least long/lat/altitude will eventually be reported every 10 minutes or so to satellites or ground stations. Today CBS has been reporting that a possible wreck has been found in the Bay of Bengal, which is on the southern route. Australian land and sea survey company GeoResonance said in a statement sent Tuesday to CBS News that it had discovered materials "believed to be the wreckage of a commercial airliner" about 100 miles south of Bangladesh in the Bay of Bengal using proprietary technology which scans vast areas for specific metals or minerals. http://www.cbsnews.com/news/malaysia...irliner-found/ You will recall that route had been decided to be unlikely based on Doppler analysis. You'll just love this error: When the decision to focus on the southern Indian Ocean was made, CBS News' Pegues reported that Inmarsat had also contributed one more piece of evidence which helped guide the move: the so-called Doppler effect. By measuring the sound waves from the plane's final pings, engineers from Inmarsat were able to determine the aircraft's location relative to the satellite; it's the same effect that makes an approaching vehicle sound different to the human ear than one moving away. The analysis of this data from Inmarsat suggested the plane had travelled south, reported Pegues. Sound waves? Unsound reporting is more like it. More importantly, though, he said that although that plane *could* land on a very short runway, not very many of the alternates proposed as landing sites would actually accommodate that model of plane without collapsing the landing gear. All airstrips, apparently, have a rating that indicates how much weight they can support.

But it's a major problem for the fire theory, because Kota Bahru had a suitable runway, they passed right by it 140 miles before contact with ATC was lost and it was the logical place to divert to for a sudden extreme emergency. Not if you believe that everyone aboard was already dead from asphyxiation . .. . I think the intent was to put the aircraft down at Kora Bahru but when the plane got there, no one was left alive to do it. That's based on there being all these altitude and course changes within a very short span of time and then nothing. Just a long, lazy flight to nowhere. In the years I spent as a reporter, one of the worst things that can happen to people is to lose a loved one amid such uncertainty, whether it's a combat MIA, a mine collapse, a missing person or a crash victim. I remember seeing a video piece about a woman whose son was killed on the Lockerbie flight. She spent hours each day sitting in his football jacket out in the woodworking shop he had built behind the house, crying. I can't imagine how the parents of all those kids killed on the Korean ferry feel. I know I choked up when I saw a piece about the recovered cell phone videos and one kid saying "Mom, this looks like the end of me." I wonder if any of the cell phones on the Malaysia flight have recoverable data and what that data would say? When "stuff goes down" nowadays everyone whips out their cell phone to make a video. Recently, when someone fell onto the subway tracks, the platform was full of people holding their phones over theirs heads trying to get a video. Fortunately one man jumped onto the tracks and saved the person that fell. -- Bobby G. |

But those altitude and heading changes continued long after it had passed the closest it ever got to Kota Bahru. And it didn't head for Kota Bahru, it passed well to the north of it. Worst of all, there was no distress call. I don't know of a commercial airplane that ever just showed up an an airport for an emergency landing without contact with ATC. Nor one that had a such a major mechanical problem or fire that resulted in the loss of VHF radios, ACARS, transponders, yet left the plane capable of flying for another 7 hours. You're in the very small minority that still thinks this was some mechanical problem. |

I'm not very sanguine about it, but anything's possible at this point. We're down to surveying every square foot of the ocean and if the plane slid under deep ocean silt, the Bluefin could scan all day and never see it.

You're in the very small minority that still thinks this was some mechanical problem. My opinion is based on two major points. One is that that model plane already had had a serious oxygen-fed cabin fire on the ground that would have been fatal to the entire plane if airborne. The second is that Boeing had issued a repair order for the oxygen hoses and I don't believe that Air Malaysia has any records indicating the fixes had been made. In addition, there's some serious debate about whether the black boxes had been replaced at the proper intervals. While the FAA and its European equivalent make sure that such serious hazards are remediated in a mostly-timely fashion (AF 440's pitot tubes being a notable and crash-causing exception) I wonder if the Malaysians are as attentive to details. The failure to replace the pinger batteries on time (if true) could indicate lax maintainence. So I find it entirely credible that an oxygen fed-fire raced through the cabin (where the hoses are routed) and killed the air crew and perhaps everyone else on board. While I may be in the minority, the fire theory is one that can be proved or disproved pretty easily when and if the wreckage is found. Other theories are going to be pretty hard to prove if the voice recorder recorded over the critical moments when the plane turned. I've read recently that the CVR and FDR can both stop recording if their busses are pulled or power to the units are interrupted for some reason. The batteries only power the pingers, not the recording functions. If true, the CVR could provide a lot of answers if it's ever found and it stopped recording shortly after the "big turn." The suicide theory bothers me because most suiciders don't dawdle. Why take seven extra hours to kill yourself? I still think the scenario of the pilot hoping to force the government to release his buddy and let him leave the country was the "ransom" demand, if any. That could account for a seven hour delay in the crash - giving the government enough time to release the pilot's friend and for him to radio the all clear from wherever he sought asylum. And when he didn't, the pilot made good on his threat. The worst case scenario for the MG would be for anyone to find the plane and the CVR if this was a hostage negotiation gone wrong. Would they deliberately mislead searchers in hopes the wreckage would become waterlogged and sink? I just get the strong sense the MG has been tailoring its responses to match any hard evidence that comes out outside of its control. I'd really like to know how that company generated those images of the item in the Bay of Bengal. -- Bobby G. |

You're trying to apply rational thought process to someone with a deranged and unstable mind. Plus, if it was a suicidal pilot, how do you know when he died?

I still think the scenario of the pilot hoping to force the government to release his buddy and let him leave the country was the "ransom" demand, if any. That could account for a seven hour delay in the crash - giving the government enough time to release the pilot's friend and for him to radio the all clear from wherever he sought asylum. And when he didn't, the pilot made good on his threat. And no other aircraft heard any of all this communication? No one involved has called up TMZ and leaked it all? And if he was waiting for Malaysia to give him something, why was the plane on it's way to Australian no-man's land, instead of circling Malaysia? This is just bizarre speculation along the lines of Elvis being alive. The worst case scenario for the MG would be for anyone to find the plane and the CVR if this was a hostage negotiation gone wrong. Would they deliberately mislead searchers in hopes the wreckage would become waterlogged and sink? The Malaysians aren't the ones telling the world where the plane went down. Inmarsat, a British company is. Are they in on the conspiracy too? The NTSB? FBI? FAA?
