CNN has been reporting a new revelation which some aviation analysts are describing as a game changer. You will recall that about an hour into the flight MH 370, then flying at cruising altitude of 35 000 feet (Flight Level 350) signed off from Malaysian ATC in the Gulf of Thailand and then disappeared from Radar after the transponder was switched off.
New reports from an "insider" now suggest, for the first time, that at the time the transponder was switched off, military radar picked up the Airliner entering a steep dive to the left, and descended rapidly from FL 350 to around twelve thousand feet before disappearing from radar. Ten thousand feet is the altitude pilots head for during emergency descents since its an altitude where one can breath normally.
Apparently, some analysts who say that this information is a game changer, now suggest that this could be a pointer to some catastrophic technical or structural failure on board as opposed to the theory I favoured from day two on common sense grounds, and which a week later, I was belatedly joined by other aviation experts.
Whilst I still favour the theory of cockpit incursion or pilot involvement or a combination of both for reasons set out in two previous blogs, published on this site, it would be foolish to completely exclude the possibility of catastrophic failure or, such a decompression.
That said, my theory remains unchanged and I urge caution in regard to the latest "revalations."
First of all, radar mostly cannot determine an aircrafts altitude or speed without receiving such information from the aircraft's transponder which was off. Admittedly military radar does have better capability than civilian radar, but I understand that one needs to be reasonably close to the radar in order for any reliability to be attached to the readings.
Secondly, the timing of the turn, which occurred after handing off from one area controller, and before being handed over to the other, (which allowed the aircraft considerable time to slip away) is a little too convenient.
Thirdly, my previous point gets even stronger if one factors in the simultaneous switching off of the transponder and the aircraft's automated reporting systems. Quite frankly, the odds of all three these occurrences, all of which are suspicious, coincidentally being accompanied not only be a catastrophic failure, but one which also disabled these systems too, must be extremely remote. Any catastrophic event with all those consequences, and which prevent communication with ATC during descent, would have to be sufficiently catastrophic to bring the airliner down within the hour, which, by all accounts did not happen.
Finally, in order to reach the present search area in the Indian Ocean on the available fuel, the aircraft could not possibly have remained at 10 000 feet for any length of time. The air is too dense here and the much higher fuel consumption would have rendered any such lengthy flight impossible.
But here's the killer point, even if we assume that all the above did occur and that the aircraft was forced by some technical emergency to descend to 10 000 feet, this does not explain why the aircraft, then, instead of landing, must have, (if all the satellite pictures and news reports are correct), then ascended back to over thirty thousand feet in order to allegedly end up where the search planes are now looking. This could only occur with the assistance of a hijacker or a pilot with ill intentions.
Game changer then. Sorry, I'm having none of it from these so-called aviation experts unless you can produce a wreckage much closer to Malaysia. So far, nobody favours any such theory.
So, all this means two things. No game change, and do take the "rapid descent" story with a massive pinch of salt for now. Of course, new and proper information could still surprise us all.

Why there has to be a referendum in Crimea.
I believe that the current impasse between the USA and Russia over the Ukraine and Crimea can be resolved by permitting a proper referendum in Crimea about whether Crimea should opt for independence, remain as part of Ukraine, or be re-incorporated into Russia.
Most of the population of Crimea are Russian speaking and Crimea was in fact Russian a generation or so ago until Khrushchev of the former USSR granted it to the Ukraine.
Why that was done is a mystery to me since Russia has always sought a "warm" water port for its Black Sea Fleet. At present, its fleet is still in Crimea by agreement with the Ukraine.
However, since Crimea is presently part of the state of Ukraine, there are various conditions which must apply to the referendum.
Firstly, since any vote for independence or for reincorporation into Russia is constitutional in nature, a simple majority in any such referendum will not suffice. In order to change the status quo, the majority should be anything from 60% to the traditional two thirds mark. Perhaps a compromise of something between that would be in order.
Since Russia seems confident of overwhelming support of the people of Crimea, this should not present a problem to it.
Secondly, the referendum must permit the people of Crimea the choice to remain a part of the Ukraine. The present "illegal" referendum to be held tomorrow is illegal for many reasons, including its failure to permit the Crimeans a choice to remain a part of the Ukraine.
Thirdly, the referendum should be conducted under UN supervision and international monitors should be permitted.
Fourthly, the referendum should permit sufficient time and a proper democratic environment for people to conduct a proper campaign. The present conditions, in which armed Russian soldiers or militia are marching about, are intimidatory and not conducive to the conduct of a free and fair poll.
If Russia is so confident of the overwhelming support it claims and, to be fair, seems to have amongst the majority in Crimea, it should have no difficulty in agreeing to the above as a compromise.
The present referendum is a farce which will not be recognised internationally.
That said, I think the West has failed to recognise the fact that the spread of the EU towards Ukraine, and the growing number of NATO countries in former Soviet Bloc countries leaves Russians feeling uneasy. Russians see the Ukraine, and particularly Russian speaking parts of it, as part of their so-called "area of influence." A failure to appreciate that Russians feel a certain solidarity with Russian speakers in this area of influence -former Soviet republics which border on Russia - will do nothing to resolve the present impasse.

Malaysian airliner MH370: How close to the mark?
http://siegfriedwalther.blogspot.com/2014/04/mh370-24-april-2014-update.html
On Sunday evening already, I concluded that Cockpit Incursion or Crew (Pilot) Sabotage was the most likely cause of the missing airliner. This now seems to have become the governing theory.
Today is Friday, and little has changed. I argued on Sunday that the Airliner, if it maintained its course, ought to have crossed the Vietnam mainland after 1hour and fifteen minutes. I argued that any period in the Gulf of Thailand in excess of that must then be regarded as suspicious since the aircraft would clearly be in the wrong place.
The initial reports were that the airliner was last seen in the Gulf of Thailand, midway between Malaysia & Vietnam, after TWO HOURS. If this was so, I argued that the last forty five minutes of the flight on radar was suspicious since the airliner was in the wrong place.
Based on this, I was able to exclude catastrophic failure as a likely cause, since catastrophic failure is usually a sudden event which occurs quickly and seldom allows the pilots a chance to communicate with ATC. Since the pilots had 45 minutes of flying at cruising altitude, I concluded it was safe to exclude catastrophic failure. Had there been such a failure it would not have lasted forty five minutes. During the said "missing" 45 minutes, the pilots would have had sufficient chance to use one of the many communication systems on boards to communicate with ATC. Even the aircraft's sophisticated automated systems would have had a chance to send automated reports during those forty five minutes. No such reports were apparently sent we were told.
This is not to say that catastrophic failure can be excluded altogether, rather that it must move to the bottom of the pile of usual causes.
Mechanical failure can also be excluded for the same reason. Any mechanical failure which permits the aircraft to fly for another forty five minutes is also one which must allow the crew and the aircraft's automated alert message system a chance to communicate with ATC.
Pilot error could also be excluded, I felt, since I could not imagine a pilot error which would cause the pilots not to communicate with ATC for forty five minutes on any platform or one which would prevent the automated systems from broadcasting messages. The absence of:
- ATC transmissions by Pilots for forty-five minutes;
- The suspicious timing of the transponder being switched off, and no other unit being switched on in its place for forty five minutes, and
- The apparent failure of the aircraft's automated systems to broadcast any messages to satellite to indicate any problems for forty five minutes
It then transpired that the initial reports might have been wrong in that the aircraft's transponder went off after only an hour, shortly after handover from Malaysian ATC to Vietnam ATC. The aircraft said goodbye to Malaysian ATC, but never contacted Vietnam ATC and the aircraft's transponder was switched off.
This, I thought was the kiss of death to my theory since it permitted Mechanical Failure & catastrophic failure to return as theories.
Worse still, the false passport theory was also generally dismissed as being unrelated.
And yet, there remained various clues to suggest that my theory of Pilot Sabotage could yet hold water:
- The Gulf of Thailand is shallow and relatively small and surrounded by many highly populated countries. The Gulf is also relatively shallow. So the failure to find the aircraft's wreckage again suggested that the aircraft may indeed have flown for some time after it disappeared from radar due to the transponder being switched off; Boats, people on the beaches in surrounding areas, search planes etc should have found something after four days.
- Reports began to emerge that the aircraft may have turned around to attempt a return to Malaysia. The longer the aircraft took to turn around, and to attempt a return, the more my theory in favour of pilot sabotage / cockpit incursion /hijacking must return to being the most prominent theory.
- The timing of the transponder switch-off, immediately after being handed over to another area controller in Vietnam, is also a factor to be considered. It will be a while before Vietnam's area controller notices that the aircraft has not made contact. This would allow a pilot a chance to switch off the transponder without drawing attention of either the former area controller or the new controller for several minutes.
- Further suggestions came to light that military radar spotted an unidentified aircraft heading from the Gulf of Thailand and crossing over Thailand. (Again, the aircraft is flying and is in the wrong place.)
- Finally, it was suggested that there was one automated aircraft transmission to satellite which also placed the aircraft somewhere heading towards the Indian Ocean. This system apparently also stopped transmitting.
- Apparently the latest is that aircraft automated messages indicate aircraft was flying on a new and recognised route towards the South West. This seems self evidently deliberate. Aircraft don't usually change course without being programmed to do so by changing the autopilot heading hold or changing the route the Autopilot Nav is using.
Taken together, and if some or all of the above are true, then it serves to exclude Pilot Error, Catastrophic failure, Mechanical failure as likely causes and it elevates Pilot Sabotage or Hijacking or Terrorism(with or without pilot involvement) by people who know aircraft systems well.
If I am correct, I still don't have any theory as to the reason for the said conduct or as to what eventually occurred. Was it pilot suicide by one of the pilots? If so, why wait so long? Was it a failed attempt to gain an airliner to use it as a missile by flying it into a US base in the Indian Ocean? Was it a bomb that eventually went off by accident. Has the plane landed somewhere and are the passengers currently hostages? I understand that many relatives are praying for this possibility which seems to be their only hope, albeit an unlikely one. I hope for a miracle!
Who knows what actually occured? These are the real questions which cannot be answered before the aircraft is found.

Missing Malaysian 777, Cockpit Interference likely scenario
See Map Below & Timeline on it:
The fact of the matter is, if one or both pilots wished to make an aircraft disappear, the moment to do so in this flight would be after hand-off from Kuala Lampur but before communicating with Vietnamese ATC.
More later....
Whilst it is inadvisable to
speculate about the causes of any air crash prior to the wreckage being
recovered and a proper investigation is conducted, certain of the facts which
have come to light scream that a deliberate unlawful act occurred.
Most likely, this involved one of the pilots, perhaps both. Others may also have been involved.
Most likely, this involved one of the pilots, perhaps both. Others may also have been involved.
We are informed by the Malaysian
authorities that the aircraft may, according to Military radar, have turned to
return to Kuala Lampur.
If the crew experienced a
sudden emergency, their failure to communicate with ATC would not be strange.
However, it is difficult to conceive of an emergency which would have prevented
one of the crew from using one of the on-board systems to communicate for an
entire forty five minutes.
If indeed the pilots felt
it necessary to return to Kuala Lampur, communicating their intentions prior to
doing so is standard protocol. Perhaps an emergency prevented this from occurring
immediately. But failing to communicate
the change in intentions for forty-five minutes is almost unprecedented.
I refuse to accept that the
pilots were unable to use one of the many means of contacting ATC to advise of
the emergency during this period. The aircraft’s transponder code can be
changed to indicate cockpit intrusion or some other emergency such as failed
radios. We know that the transponder was probably working since this is how the
flight was tracked and identified.
Apart from various radios,
an on board “texting” system also exists.
I can only conclude that
if neither pilot was involved, other parties, must have prevented the pilots from using any of these
methods to communicate during the controversial last forty five minutes of the
flight. Alternatively, it seems one or more pilots chose not to use these methods to communicate.
The fact of the matter is, if one or both pilots wished to make an aircraft disappear, the moment to do so in this flight would be after hand-off from Kuala Lampur but before communicating with Vietnamese ATC.
More later....

Malaysian Flight MH370 777 Missing
See Blog of http://siegfriedwalther.blogspot.com/2014/04/mh370-24-april-2014-update.html
for last and latest update
Malaysian 777 missing on flight from Kuala Lampur to Beijing, China. Reports suggest aircraft went missing two hours into flight. If so, reports from a Vietnamese Naval officer that the aircraft went down in near Vietnam in Gulf of Thailand makes no sense. It would take no more than one hour and fifteen minutes for the 777 to cross the Vietnam coast from Kuala Lampur. i.e. Unless the aircraft had problems or was forced to turn around.
Edit: It now seems that the airline dropped from radar one hour after take-off. That would indeed place it in the Gulf of Thailand, around 15 min cruise flight from crossing Vietnam's coast. Estimate it crashed around 200km from point it would have crossed mainland, all things being equal.
The lack of any ATC transmission or any electronic transmissions from any automated systems suggests, unfortunately, a likely catastrophic event or mid-air break up.
Structural damage? Terrorism. Another Air France 447 type incident is unlikely despite the similarities. There were too many accidents like that prior to 447 to prevent all airlines from learning the lessons about how to deal with pitot tube failure and about how to handle airliners at high altitude.
The fact that two passengers were on false passports is worrying. Can't imagine that anyone on a false passport would pick China of all countries to try and mislead authorities. The price for failure would be very high. Leads me to wonder whether they intended to reach their destination.
Anyhow. Will have to wait for more evidence before trying to work out what occurred.
