    Wow. Incredible. This is the most feasible scenario of them all. The proposed AD, and lack of anyone mentioning it is quite astonishing. Can’t wait to see what unfolds once this gets out.

  • Danny

    This article wins the Internets today, hands down.

  • Boeing777

    Well researched article! The best I have read so far. Now, clearly understood about why the phones of the flight passengers rang. One possibility here – What if the plane was hidden with electronic weapon? http://timesfeed.com/scienceandtechnology/malaysia-plane-hidden-with-electronic-weapon/

    have to check whether the particular MH370 aircraft has carry out this AD or not or if they are excluded or if they carried out penalty servicing such as Non destructive inspection like x-ray on that affected area.

  • berosos_bubos

    So just how many hours would it have had to be flying for to pick up those calls ? It would have circled the globe. Instead it must have crashed in shallow water or over land.

  • paddylaz

    Seems a bit unrealistic.

    My theory: Kim Jong-Un has made a deal with alien forces for world-domination. In exchange the Claatu have given him electromagnetic pulse technology that perfectly accounts for the loss of electrics on the plane (hence lack of communication). Kim’s end game is a sort of pan-asian power play triggered by finger-pointing following this ‘disaster’.

    • Langalanga

      You stupid moron.

    • Hattori

      And your theory is realistic?
      Ha ha!

  • Luke Bozier

    I agree that this scenario is the most likely, and when I read the FAA papers myself – before reading this piece of yours – I came to the same conclusions. The 777 is a wonderful plane, I’d be really sad if this is what’s happened, but it’s looking increasingly likely.

    The big question is: Where did the plane glide to, and where is it now? A) Could have landed on water somewhere – a la Hudson River Airbus – people could still be alive, if the plane is relatively in tact, the mobile phone system might still work. B) It ditched somewhere around the Malacca Straits, in which case I’d expect it to be found by the end of Wednesday. C) It flew of thousands of miles into the Indian Ocean and is now at the bottom of that ocean.

    Interestingly, the Malaysians said it was at FL300 (3,000 feet) when it passed over the tiny island in the Malacca Straits. So likely then that it is in those waters now.

    • izaman

      FL300 = 30,000 feet

  • dave

    please dont spread unconfirmed reports

  • Bullshit detector

    this was told by another guy with the route up to north instead of to west , guess this guy just stealing ideal from the original but change the patch just after speculation on military radar detected MH370 heading to Malacca strait .This was denied again this morning . Guys , don’t too fancy with this kind of report . They just want to be popular .

      The entire article was based on the original posting at http://mh370lost.tumblr.com/?og=1 . It was mentioned and credited accordingly throughout the article.

  • andy

    This seems the most feasible explanation, although it doesn’t explain why the transponder also went off. I might be wrong here, but I believe it used a different antenna. Also, it seems somewhat unlikely that the pilots would be hypoxic enough to not wear their oxygen masks or change radios but would be able to turn the plane around and descend. Also if this was the case, then presumably it’d still keep flying on autopilot until it ran out of fuel.

    • Vijandren Ramadass

      I’m still trying to get more information on the transponder going off from people who have experience with the plane. There really isn’t enough data or research to ascertain how different people operate when deprived of oxygen.

      • Anthony Cirinelli

        How do we know the transponder was ACTUALLY disabled. I checked the flight the following day and flightradar24 loses contact at IGARI (same location) and regains tracking at Vietnam.. It could be something irrelevant of the 777’s transponder.

        • storm17

          Precisely. At present time, none of us out here knows anything. Any theories put forth is therefore just that: nonsense.

          • sparky

            Actually storm17 you are completely missing the point of theory – to develop feasible avenues to investigate, possibilities to eliminate or consider further. Vijandren is suggesting some possibilities that may fit with the few (perplexing) know facts – a starting point to investigation – not a conclusion.

          • storm17

            “Known facts” sounds nice. Except that it was already pointed out earlier on that the whole basis for this particular premise — resting on the FAA alert regarding the antenna array which could rip the skin off the fuselage — is (likely) false.

            I put likely in brackets to be generous. The poster — and the original author whom he swiped this theory from — have not addressed the simple question: is it true MH370 was not fitted with this particular antenna?

            Disregard that and the whole “theory” crumbles. No slow decompression. No pilots in a half-daze. No phantom plane flying on into the night as everyone on board slept. Just, you know, fanciful nonsense.

          • storm17

            Just in case you missed it, here’s the official document to support my previous assertion re. facts:


        • Naziem Rashid

          the one u posted tat have been traked at Vietnam is 9M-MRQ which safely landed on Beijing, while the one tat went missing is 9M-MRO.

          • Anthony Cirinelli

            Right, that’s my whole point. The flight the following day lost tracking at the same location. Therefor MH370 9m-MRO losing tracking at IGARI is not an anomaly. There is no proof the transponder was shut off or disabled in some way. All we know is they lost radio communication, indicating either A: they went down, or B: Satcom went down (did it come off, who knows)… It is possible this bird went down whole, and sunk to the bottom somewhere.

        • BB

          I’ve read that a change in altitude can cause loss of radar signal … which fits in … don’t know it it’s true, tho.

      • BB

        Only loose end is why reports are coming through that the plane’s tail was on fire. Otherwise, this theory is only too realistic … at least passengers passed away in peace. RIP poor souls.

  • Sam

    The Airworthiness Directive you reference did not apply to the Malaysia Airlines 777 in question. It was equipped with a different satcom arrangement. Also worth noting is that the cockpit crew would have been amply warned of any slow to moderate increase in cabin altitude (depressurization or over pressurization) well before it got the the point of incapacitating anyone. Airplanes fail to pressurize or, in general, have cabin pressurization issues at times. More than people might think, honestly. Procedures for such scenarios are trained for the safety of passengers and crew.

    • PDav36

      It may or may not be what happened, but the directive specifically refers to risk of “rapid decompression
      and loss of structural integrity of the airplane.”

      • Sam

        This particular 777 had a completely different satcom arrangement. Again, this AD did not apply to the 777 in question.

        • Ruby

          BUt even if the AD did not apply to this particular plane, could not a similar scenario still occur — i.e. a simultaneous loss of communication and decompression? I was under the impression that effects of hypoxia at 35,000 feet would set in pretty rapidly, so even if there was warning, I wonder if this could still play a role.

          • Sam

            Anything is possible. The airplane won’t quit flying if the radios stop working,
            though. And there are some very famous instances of rapid decompression due to structural failure where the airplane was able to be flown safely for an emergency landing.. Read about Aloha 243, United 811 and Southwest 812.

    • Vijandren Ramadass

      I would appreciate if you could point me in the right direction on the satcom arrangement for MH370. While the FAA AD would not have applied, it is a possibility that the 777-200ER would have had a similar issue considering it has been in service longer then the planes refereed to in the AD.

      • Sam

        Find an image of a Singapore Airlines 777-200. You’ll see the Boeing satcom plainly, several meters forward of the vertical stabilizer. That’s the satcom that the AD applies to. You won’t find the same antennae on any Malaysia Airlines 777. Confirmed this with a co-worker who is an avionics technician.

        • sparky

          So Sam, what Antenna will you find on a Malaysian airlines 777? The problem Vijandren and the sources he quotes is potentially relevant and should be considered. It is a hypothesis to examine and test against details of the plane to see if it can be eliminated as a possibility. It is worth examining the feasibility of this theory properly (with correct specs of plane) rather than dismissing off hand, because not all details co-incide. Vijandren isn’t selling a conclusion – he is presenting a possibility we should probably examine properly to see if it can be discounted.

          • Sam

            Satcom on Malaysia’s 777s is manufactured by Honeywell and uses a different antenna arrangement. Malaysia had the units installed after delivery from Boeing. Different antenna than the one referenced in the FAA AD and by the author of this piece. I can’t make this any simpler than to advise that you look at a 777 that has the Boeing factory satcom system referenced as the “suspect” antenna in the airworthiness directive (Singapore Airlines and American Airlines are two carriers that have it installed) and then try and find the same antenna on any of Malaysia’s 777. You won’t….because it isn’t there….because it was never installed….so there is no chance for the associated fatigue cracking….because AGAIN this airplane didn’t have the antenna….so this theory is junk. Clear enough?

          • storm17

            “What antenna will you find on a Malaysian airlines 777?”

            No idea. But on MH370? Definitely not the one being the basis for this particular conjecture, sorry, ‘theory’..

  • dave

    keyboard pilots like us will always believe whatever cooked up by other keyboard pilots.

  • Joe

    Issue with your argument: only 19 of the phones were able to ring. According to a telecoms engineer commenting a more likely scenario is that these passengers did not turn their mobile phones off on take off and so were not de-registered from their local telecommunications cell. This means that the phones remain callable so to speak for a significant period after loosing contact with the cell.

    • Vijandren Ramadass

      The mobile phones ringing is one of the more far fetched theories on this article (as well as from the original article). If the flight was equipped with Aeromobile roaming, and the 19 phones were not turned off (and had overseas roaming turned on), it would have connected to the Aeromobile service.

      • Sam

        AeroMobile says that their equipment was never fitted on any Malaysia 777s. That’s their claim, made to CNN this morning (3/11).

  • Narayanaswamy

    If the satcom had ripped off and they were disoriented, how did they manage to see their current location and change course towards Kota Bharu Airport? If the satcom was ripped is there a way to find their current co-ordinates?

    • Vijandren Ramadass

      SATCOM is a communications antenna array. It is used to relay voice and data communications via satellites back to the ATC. I do not believe that loosing the SATCOM antenna array would have affected navigation in any way.

      • Nola Yank

        There is a problem with this theory. There is a beacon over the straits of Malacca that detects commercial transponders, even if the plane is flying low. If the plane indeed turned back and flew over the area, the only way this beacon would fail to pick up the transponder would be if it failed or was turned off – not simply because it was below 30,000ft.

        • Vijandren Ramadass

          Agreed. Still do not have a more conclusive explanation to what happened with the transponder. There is a theory that the SATCOM antenna array could have taken out or damaged the GPS, ACARS, ADS-B and ADS-C antenna systems as well – but there is no way to confirm this.

        • Timmy

          I dont come close to being even a “Key board pilot”
          But i noticed it was mentioned above, that some other plane in the same area as this fligt also losed its “connection”
          Could this be due to, that in this area they will have to change frequency because the flight leaves controlled airspace, and will have to change to another ATC unit???
          Qustion would be, what will happen if one sets ones course against a “wrong beacon” (say one in Africa or some), would the plain then stay in “stand by mode”?, making the ATC radar lose target information, since the plain would never receive any squawk i presume. Dont know if my question make any sence as I as said are not familiar with anything about aviation transponders, but what do you guys say??

      • Kim Howard

        Everybody thinks the pilots are from Kansas USA. They are not. In this part of the world, face and honor are worth far more than life (there are honor killings every day in the subcontinent – parents cutting their daughters throats. The Captain and the co-pilot were new together I believe. One was very professional. The other a clown – smoking and breaking many rules. Very obvious that friction, argument and violence broke out soon after leaving the ground. Probably the Captain would have threatened dismissal. After violent struggle, the younger fellow felled or killed the captain. Human instinct is to get away from crime – not proceed to Beijing or land back at KL. So plane turned around. Signs off normally to air traffic control then turns off tracking transponder. Cabin crew banging on door after hearing the goings on. Copilot thinks may break in (he doesn’t know what we now are told on this). Flies up to 40,000 ft and all knocked out. Copilot has more oxygen and not affected. He makes sure all dead then has to dive fast to 15,000 feet – as his oxygen is running out. Then realizes that he has no way out. Even with suicide, the voice recorder will show his role and disgrace for him and family. Only option – take the plane where it not be tracked on radar and will never be found – deep into southern ocean. He was a smart fellow and like many – one moment of impulse caused it all. The Captain also at fault by obviously inciting/provoking. He should have been smart enough to calm it down and act when on the ground.Nothing the matter with the plane. Captain obviously unconscious or dead early. Only the copilot talked to sign off. Otherwise waht was the Captain doing – sleeping for the 7 hours. No chance that 2 so opposite people could conspire to take the plane down there. In terms of motive – the so called experts have forgotten one of the most basic motives – to hide a crime!

        • Vijandren Ramadass

          Here are the reasons why this would not be possible.

          1. If the passengers knew something was a miss (banging door etc), they could have made a distress call with the onboard sat phone.

          2. You don’t learn how to fly in and out of radar by instinct. You need to have pre-planned it, and learnt and studied the location of radar stations.

          3. You can erase the cockpit voice recorders once you land.

          4. Killing the pilot (without a weapon), in a confined space like a cockpit would make the co-pilot a trained assassin. There doesn’t seem to be any indication he was moonlighting as one.

    While we’re at it, the Helios 522 crash had nothing to do with a malfunctioning pressurization system and everything to do with a flight crew that failed to follow checklists and procedures. Pressurization system on the Helios 522 airplane (Boeing 737) worked fine. It wasn’t configured correctly. The flight crew received a cabin altitude warning and had time to descend below 10k feet and troubleshoot their problem safely. They kept climbing, and we know the rest of the story.

    • Vijandren Ramadass

      The Helios reference is made to explain how an aircraft would continue on its flightpath even if the pilots were incapacitated by the lack of oxygen. The Helios flight continued on its pre-set destination and continued to hold a pattern above the Athens airport without any inputs from the pilot until in ran out of fuel.

      • Sam

        I find it hard to believe that a Captain with over 18,000 hours total time would ignore the warnings, both audible and visual, of a dangerous cabin altitude condition brought on in the manner that you propose (slow increase in cabin altitude due to ). Possible, yes; the Helios flight crew ignored it after they seemingly skipped their checklists, and forgot how to handle a regularly practiced scenario. But plausible? No way. Not with a guy with 18,000 hours as the pilot in command.

        • storm17

          And has a flight simulator installed at his home, to boot. So theoretically, more than 18000 hours accumulated.

      • storm17

        Bro, I don’t know if you have any training or expertise in aviation technology, but it is quite apparent that the person you are speaking to does. I would defer to someone with more knowledge than me instead of lifting something off someone else’s Tumblr feed and then adding your own conjecture.

            Basically he pinched someone’s article off the Net, added his own conjecture, and judging by his comments down here is now “owning” it as his. For reasons known only to him.

          • sparky

            Ah no storm 17..if you actually read the article you will see that he clearly credited the sources from the start!

      • Timmy

        Actually it has been reported, that U.S. investigaters, suspect the plains engine kept running for about four hours afther its last know momnet of contact. Based on an airspeed of 480 knots, this means, that the plain precisly could have made it to!!!!!!! ….Beijing!
        Meaning that it would seems plausible that the plain (probaly) crashed, at the time, where it should have reatched its planed destination due to lack of fuel!!!! I believe this support the “Helios hypothesize”

  • Matthew Ong

    I think now is the time for Boeing and Airbus to think how to increase the airplane safety features, vehicle we got air bag, VSA/VSC/VDC, ABS/BD/BA……. , but until now airplane do not come out any safety features land the plane safely even the engine problem or other technical problem. I think these 2 company already got some planning to increase the airplane safety features long time ago, just who is going to pay for it and maybe they think the percentage of airplane crash is very low, so not worth to invest in such thing!

  • InvinceZ

    I think got report another air craft manage to make contact with the MH370, but all they hear was all hissing and mumbling. the location was north / north-east, not west or east or south.

    not sure it was debunked already or not.

    • Vijandren Ramadass

      This was covered in the article. The other aircraft was able to make contact with the MH370, not via SATCOM, but possibly through the VHF band which would have had a limited range. The mumbling could have been an indication that the pilots were struggling with hypoxia.

      • storm17

        “The mumbling could have been an indication that the pilots were struggling with hypoxia.”

        Neither you nor the original writer of this conjecture knows that for sure.

        You don’t know that for a fact. Nobody does. Yet you write with such conviction. THAT is the real mystery here. Absent hard evidence, any probability is possible. And it is easy to shoehorn facts to fit a preconceived conclusion, surely?

        In fact, you — and we — don’t even know the _quality_ of the mumbling. Was it mumbling due to the bad connection? Can you tell us? We don’t know either. But the difference is, we don’t go and write an article to declare what we think.

  • Derek

    This sir, is the most informative article I’ve read for quite a while. All theories state is likely to make plausible cause for what had happened to MH370. Very good write I must admit.

  • Quentin

    What about the transponder?

  • Андрей

    So,the plane must have crashed somewhere in the Indian Ocean,thats why no traces of it in the areas of the search.All the facts then add up.
    At least passengers did not die in a terrible way,God bless them.

  • CE

    Related to the information on the flight that professional golfer Payne Stewart and others perished in South Dakota, USA: the plane suffered from rapid depressurization after a normal takeoff…about twenty minutes into the flight. The plane remained on autopilot and crashed approximately 1,500 miles from it’s original location.


  • Raj Thackersey

    Guys don’t rack your brains Raja Bomoh must have already located the jet using his bamboo binoculars

  • DragonFartOutLoud

    Pretty good read but this theory has been debunked as improbable by a veteran aircraft engineer on Reddit (http://en.reddit.com/r/news/comments/205k0i/comprehensive_timeline_malaysia_airlines_flight/)

    A Knowledgeable and Sensible guess that might help the recovery of MH370. I pray this will help everyone .

  • shaz ferouz

    it would explain why there was no distress call, but not why the primary radar was turned off.

  • joe

    I also read about the (right)wing being previously broken and repaired. What if there was stresses further in the wing that were not noticed?

    Could the wing have broken on its right turn it made just as it went off radar, and possibly struck the fuselage because it was in a right bank? maybe right at the top where the satcom and adf antennas are and maybe possibly hit the APU fuel line, VOR/VHF C connections in the rear. That could explain flames from the tail by witnesses, or else a leak from the wing tank.

    All of that would cause alot of alarms and panic at once on the flight deck, perhaps distracting them from decompession issues, and maybe they quickly turned to the closest vector(Kota Bharu), dropped 5000ft, then were over come with hypoxia. Then continued to fly on auto pilot on their set heading (indian ocean) until gravity set in

    • anonymous

      Given that this is the only reported major mechanical damage to this B777, suggest MH / Boeing take a closer look at the repair and inspection records for this as a possible root cause. Sorry this post doesnt help with locating this craft.

  • curious99

    It’s already Day 5, yet no sign of the wreckage. So, the plane may not be in the Gulf of Thailand but further west. If it’s on autopilot, it may have even gone down into the Andaman Sea.
    At this moment in time, this theory seems to answer and address the questions surrounding the mysterious disappearance of flight MH730 in a credible manner.

  • clare

    MAS planes only had the Aeromobile service for a trial in 2009. It’s not currently installed on their planes so unfortunately that aspect can be ruled out.

    • Vijandren Ramadass

      Thanks Clare, we will update the article to reflect this new piece of information.

      • storm17

        Could you share what is the maximum range of VHS communication that you mentioned was used between the two planes?

        • Vijandren Ramadass

          The maximum VHF range would have been up to 200 miles, depending on a few external factors like weather.

  • Matthew Gaunt

    I lost interest in this when I got to “ADS-B isn’t able to track aircraft flying below 30,000ft”, which simply isn’t true! Indeed, the Wikipedia page on ADS-B lists one of its benefits as reducing the possibility of collisions under 1,000ft.

    Since the theory hangs on that premise it doesn’t feel viable to me.

    • Vijandren Ramadass

      Ok, this can be explained based on the same wiki article. ADS-B can work as a collision avoidance system well below 1000ft by ‘talking’ to another aircraft equipped with ADS-B within close proximity of each other. It’s capacity to communicate back with ADS-B receivers however decreases when it drops below 30,000ft.

  • malabamodel

    Correction: Helios Fight 522 was in August of 2005, not December 1997.

    • Vijandren Ramadass

      corrected. thank you 🙂

  • Bum

    I calculate that the plane’s ground speed would have been well over 500kts for it to have travelled from its last known point to the possible Malacca position picked up on radar in 45 minutes. Do you think this is reasonable with an easterly tail wind? At the very least, any broken fuselage would not have been interfering with its speed if this scenario were true.

    A quick look on flightradar24 shows flight SQ68 was in this position at 2:15… Possible confusion?

    Aslo – is it worth correcting that map you have? It states radar position of object was at 1000ft – reports say it was at 29500 ish!

  • noryume

    Not likely to happen. But can happen. Lost of communication is still a mystery. Even though the SATCOM fail, all other antenna still there. There are not bundle up together in the same area. As Helios case, the warning is there. The pilot know about it. They react to it by contacting ground but pilot make mistakes. For MH370 as if no warning about cabin decompression happen. Aircraft is not like your car. Every system have it backup system. It is very unlikely all the communication systems inoperative at the same time.

  • Qantas32

    Very interesting and plausible idea, assuming the airframe was intact and it followed towards pulau perak on autopilot. It might have followed a path like this, which would be a useful place to direct search operations – http://www.gcmap.com/mapui?P=kbr-sez,kul-pek&MP=ortho&MC=HRI&DU=km

  • Five yankee

    So, the pilots don’t notice the cabin alt readout, right in front of their noses, are deaf so they don’t hear the cabin alt audible alarm, forget where their O2 masks are located? In the rear, cabin masks deploy instantly, so what is 13500ft got to do with it? Useful consciousness is not 5 seconds, even at 30,000 ft!stick to FSLIC I suggest!

    • Timmy

      They dont detect the (2) rapid cabin depressurization alarm, because they have shut it off together with the (1) smoke detection alarm, in order to be able to smoke on board (as they should be known of doing), …AND they migth not be “seaded” due to be tacking pickures og them self with some blondes, they have invited into the cocpit. Sounds like a joke of course, but infortunately seems to be what have been happening before with this cruw.
      Or so it says int the papers at least. RIP.

  • Jim


  • Jim

    This is a brilliant analysis. Props to the author. I was thinking the plane may have flown out over the Indian Ocean on autopilot, in which case it may never be found.

  • Capt. Dave

    Captain “Sully” Sullenberger, pilot of US Airways 1549, which landed safely on the Hudson after a bird strike in January 15, 2009, told CBS in an interview today, “the sudden loss of radio transmissions from MH730 may be understandable. Pilots are trained to “aviate, navigate, then communicate.”
    If the aircraft was indeed in the throws of a catastrophic failure, and headed for population centers in China, it is quite possible that their last conscious act was to turn the craft and set the autopilot toward the Indian Ocean. The speculations and theories will continue until some hard evidence is found. Right now, we have none,

    is the oxygen concentration in the cabin measured? if it is measured and drops below 21% oxygen is supplemental oxygen automatically deployed?

  • storm17


    “Was there a problem with the MH370 aircraft? NO.”

    Boeing has issued an official statement to say the directive does not affect this particular model. Which is what has been said here previously.


  • storm17

    Another reason why the above hypothesis is mistaken. Commenting on the original Tumblr article:

    “Xr Rider:
    However, the early contents seems to point out to Pilot Incapacitation due to gradual loss of cabin pressure. But that does not answer the fact that there will be a loud horn when the Cabin Pressure is below a safe minimum. The horn is loud enough to wake the dead up.”

    If all those communication systems like ACARS and are so important why then pilots can completely turn it off from cockpit ? Shouldn`t they always be turned on ? What is the common reason for turing them off ? I mean when normally pilots shut these systems ?

      The transponders need to be turned off during take off/landing as if all the planes in the airport has their transponders on while they are on the runway, the secondary radar will have all the aircrafts overlays on the same spot and you wouldn’t be able to make out a plane from a giant blob on the screen.

    hi guys , I am a pilot myself & it’s really a confusing to think about the whole situation, I woke up at 2 am last night & came up with this theory that if the aircraft didn’t suffer from a pressurization issue it could have simply been a matter of Carbon Monoxide poisoning that entered the aircraft & at anytime after 12-1 am its easy for anyone to fall asleep including the Pilots .
    These airplanes are highly sophisticated & a simple touch of the control column from an unconscious Pilot could override the autopilot change the direction of the airplane & even send the Aircraft in a worst case nose diving probably sending it to the bottom of the ocean .
    Just a simple theory as sometimes the simplest problem may be overlooked by investigators who are looking for something big such as the Aircraft exploding in flight.

    Clear air turbulence?

    Just one objection.
    If there is no more satcom antenna how can we explain the Pings sent during 7 more hours?

    Boeing 777, 747, 787 and MD-11 flight 111 has had fire in the cockpit

    As of March 2014, the 777 has been in 10 aviation accidents and incidents, including three confirmed hull-loss accidents of the 777

    Malaysia Airlines 777 did not buy the full package for their 777 inducing ACARS

    Rolls-Royce spoken person has stated that engines where
    not sending out any data

    Boeing has reportedly clarified the 777-200ER Malaysia Airlines aircraft did not have such an antenna installed and was not subject to the FAA order. In a brief statement sent to the Guardian, Boeing said: “The
    antenna covered by the pending AD was not installed on MH370, so that airplane is not subject to the AD or the related Service Bulletin.

    Am a retired aviator, engineer and professor. To become wise, one must be skeptical about everything all the time because without multiple source validation, never trust what people say just because they say it. Otherwise, you can become a victim just like in the Nigerian email scams that stated send me money and I will send you money because I said that my offer was legitimate. Do not believe what Boeing said. Become an intelligent skeptic and read what other aviation experts are saying.

    For example, I continue to assert that MH370 experienced a rapid decompression at FL 350 caused by structural cracking near the satellite antenna because other aviation experts as well as a former inspector general at the US department of transportation disagree with Boeing’s assertion. Just because a different antenna was present does not always mean the future structural integrity of its environment changes. This air-frame had over 53,000 flying on it. This is approaching is maximum life span and the aircraft was only about 12 years old, which means that it was extensively flown and should have been inspected for cracks to maintain consistency in the inspection process, no exceptions. That is what an air directive is for.

    Consider this, the Scotsman reported the following: the US air safety watchdog warned six months ago that the model of jet that went missing six days ago on a routine flight from Malaysia was vulnerable to mid-air break up and drastic loss of cabin pressure due to cracks in the fuselage. A Federal Aviation Administration (FAA) directive cautioned that, unless airlines acted, their Boeing 777 aircraft could suffer rapid decompression and loss of structural integrity…A gradual decline in oxygen levels as it gained altitude may have gone unnoticed by the crew until it was too late and they became disorientated…In the FAA airworthiness directive, issued on 18 September, airlines were given a deadline of 9 April to detect and correct cracking and corrosion in the fuselage skin” underneath the satellite communication antenna adaptor (sic) on the aircraft. The alert said one airline had found a 16 inch crack in the fuselage of one of its Boeing 777s. There are about 900 Boeing 777s operated by more than 60 airlines around the world. Given the Boeing 777 crack issue, Boeing strongly [ARGUED] that the FAA alert did not apply to the type of jet used for flight MH370 as it had a different antenna to the rest of the 777 range, but [other] aviation experts [COUNTER ARGUED] whether the faults highlighted in the directive may have played a part in the plane’s disappearance. Mary Schiavo , a former inspector general at the US department of transportation, [COUNTER ARGUED]: The warning said the 777 had a problem with fuselage cracking. I wonder what didn’t get done. If this plane had a problem and it had cracking or some sort of a rapid decompression and lost the ability to communicate, it would make perfect sense, end quote. Detailed sources are available upon request.

    The liability in the horrible tragedy of MH370 will likely be decided in a court room because Boeing corporation and Malaysian Airlines will probably not want to have to pay-out millions of dollars to surviving families.
