The Location of MH370

News sources are reporting that U.S. Intelligence officials are leaning toward the theory that "those in the cockpit" were responsible for the mysterious disappearance of the commercial jetliner, Malaysia Airlines Flight MH370.  Not knowing exactly what happened to Flight 370, speculation centers around theories of hijacking or foul play by the pilots.  These theories that are presented as the most probable cause of what happened to Flight 370 involve breaches in security and fear that resonate an ever present culture of fear over the past 13 years.  While we do not yet know all of the facts behind the disappearance of Flight 370, we should not resort to terrorism as the cause, and we should use sound judgement and scientific reasoning when proposing theories. Some officials, who do not fully understand the cause behind events speculate on theories revolving around fear.

I would like to present my theory of what happened to Flight MH370, using more sound judgement and scientific reasoning.  I received my degree in Aerospace Engineering from Iowa State University, where I specialized in Flight Mechanics and Structural Failure and Fatigue. I began my career working at NASA's Johnson Space Center in Houston where I worked in the Flight Design and Dynamics Department for the Mission Operations Directorate.  There, I specialized in crew flight procedures, radar, and navigation systems. After NASA, I worked for Boeing on the V-22 flight control system, then later for Motorola specializing in radio frequency communications and how RF signals propagated.

What most likely happened to Flight MH370, was that fatigue cracking occurred on the Boeing 777-200 series aircraft.  On July 23, 2012, The FAA published an Airworthiness Directive (AD) (FAA-2012-0149-0004) for Boeing Company Model 777-200, which was prompted by reports of fatigue cracks in the lap joints, and an Airworthiness Directive to detect and correct such fatigue cracking, which could grow large and cause sudden decompression and the inability to sustain limit flight and pressure loads.  This AD was updated on April 15, 2013 to include scribe lines where external decals have been applied or removed across lap joints and large cargo door hinges. In addition, on April 2, 2009  the FAA issued an airworthiness directive (AD 2009-02-05) regarding the airplane information management system (AMS) to prevent an unannunciated loss of cabin pressure, which if an undetected loss of pressure event were to cause an unsafe pressure in the cabin, the flight crew could become incapacitated.

The last known position of MH370 was at 1:21 AM at 35,000 feet, roughly 90 miles off the east coast of Malaysia. At around 1:30 a.m., the aircraft's transponder stopped responding. Under the theory that a sudden decompression occurred at that time due to fatigue cracks, the pilot and copilot would have had 15 - 30 seconds of consciousness to quickly address the problem.  If they were aware of the decompression through an annunciation loss of cabin pressure, they would have put on their oxygen masks, turned off the autopilot, begin their descent to below 10,000 feet, and head for the nearest landing spot.  If they did not place their oxygen masks on first before they began their descent, or if they attempted to troubleshoot the issue before putting on their oxygen masks, they would have lost consciousness before they reached 10,000 feet.

With the plane not on auto-pilot, in a descent with unconscious pilots, one may think the plane would crash, but this is where flight mechanics, aircraft stability and flight controls play a role in what happened to flight MH370. As the plane descended on its own, (without auto-pilot and unconscious pilots) it would continue to pick up speed to a point where the increasing speed creates more and more lift over the wings. When more and more lift is created, this force causes the plane to pitch up.  The plane may have descended to 23,000 feet before it began the pitch up maneuver.  At that point, the aircraft is pitched up and begins a climb.  It will continue to climb until the atmosphere becomes thinner and thinner and less and less lift is produced over the wings. This would typically occur at 45,000 feet. This roller coaster ride would continue between those two altitudes until the aircraft no longer has fuel to power the engines.

This pitching up and climbing and then pitching down and descending, accompanied by speeding up and slowing does is one of the basic flight dynamics modes of aircraft, and is called the phugoid mode.  I have to thank Dr. Pearson at Iowa State University for drilling this into me in his flight controls class and  Dr. P.J. Herman who taught flight performance where we flew a plane and demonstrated the speed stability of an aircraft by placing it into a phugoid mode.

Few may remember Payne Stewart who died in October 1999 when his plane experienced rapid decompression and his plane continued to fly for almost four hours after a rapid decompression had occurred and the flight crew was incapacitated. Two North Dakota Air National Guard F-16 intercepted the plane and identified that the cockpit window was iced over and there was no movement of the control surfaces of the plane.  During the plane's flight, the aircraft's altitude reached a maximum of 48,900 feet.  The NTSB added a commentary on the cause of the accident that stated.
Following depressurization, the pilots did not receive supplemental oxygen in sufficient time and/or adequate concentrations to avoid hypoxia and incapacitation.  A possible explanation for the failure of the pilots to receive emergency oxygen is that their ability to think and act decisively was impaired because of hypoxia before they could don their oxygen masks. Research has shown that a period of as little as 8 seconds without supplemental oxygen following rapid depressurization to about 30,000 feet may cause a drop in oxygen saturation that can significantly impair cognitive functioning and increase the amount of time to complete complex tasks.
While the transponder was shut down at 1:21 AM, this could have been caused by the rapid decompression and an electrical failure, or by the pilot, in a hypoxia state attempting to set the transponder code to 7500 to indicate an emergency, and accidentally turning it off in confusion.

With regards to the Aircraft Communications Addressing and Reporting System (ACARS), most commercial pilots would have no idea how to disable all of the communications systems.  More than likely additional structural failures occurred during the 5 - 7 hour flight while the plane was experiencing high stresses as a result of the phugoid mode that the aircraft was experiencing.

The reason the aircraft has not been located using ACARS is because one can only determine the distance the aircraft is away from the satellite based on the communications angle, it does not have enough information to determine the bearing, and thus based on the range of the aircraft, it could have flown north through China, or south in the Indian Sea.  Since no radar contact occurred if the plane was on a northerly route, the plane is more than likely took the southerly route, and continued flying until 8:11 am, when the last confirmed ACARS transmission occurred.

According to a map released by Malaysian officials, the aircraft's location was along a constant declination from the ACARS satellite of approximately 40 degrees:


And given the assumption the aircraft would have been spotted by radar along the northerly trajectory, the most probable location is in the south Indian Sea, away from any land or radar.

飯尾奈穂:
White chocolate with menstrual blood in it…huh…I guess that the amount of menstrual blood a normal person would loose would be a few mls, right? I reckon that if it was about that much, and you didn’t mix it in too much, then there’d be a nice amount of red in it and it would be fine, but I wonder…
みやち°わ:
It’s normal for you to mix in your blood and spit in the honmei choco, right????????? Oh???????
°˖✧クソ幼女みかにゃん✧˖°:
I mix in menstrual blood with my honmei choco every year.
うるとらきゅーとえんじぇる吉田ぽち:
If I get my period on Valentine’s day, then I can put my secret ingredient in.
うるとらきゅーとえんじぇる吉田ぽち:
Please gods. Please send me my period on the day I make my Valentine’s chocolates.
人生おつかるーあ:
One of those girls who quietly mixes her own spit into the Valentine’s chocolates.
アミノ酸:
If I’m making Valentine’s chocolates, I want to put my own blood in them.
樋口 結慈:
My suggestion to those people who are trying to mix their blood into hand-made chocolates for Valentine’s day is frozen raspberries (framboises). They look like dried, congealed blood, and because more than anything they have a tart taste, they’ll make people think that it’s blood.
ニャスパーちゃん:
It’s Valentine’s in just two weeks’ time. All you virgins who’ve never received chocolates probably don’t know about this, but in hand-made chocolates from girls, at the very least, there’ll be blood and spit, and hair that has been ground finely in a mixer. Since these are hand-made from the heart, please be sure to eat them alone in secret ♥︎
きゃさりん。:
If you want to put something of your own into honmei choco for Valentine’s day, I think that it’s actually best not to put hair, or pubic hair, or blood that you’ve got through the normal way, but rather to put those chunks of liver things that you get when you’re on your period!!! I mean, menstrual blood is the lining of your uterus, so doesn’t it excite you to think of him putting that in his mouth? What’s more, because it’s hard, he’ll never find out! Magnificent!
死にたいちゃん:
I’ve got a mental illness, so I’m going to get some blood from my nose and put that into my Valentine’s chocolates _人人人人人人人_ >  NOSE BLOOD  <  ̄Y^Y^Y^Y^Y^Y^Y ̄
大図書館のロリコン:
I always put raw chocolate in my Valentine’s chocolates, but I’m putting in blood as well.
✁✂✃✄あるせ✄✃✂✁:
Yey, Valentine’s!! What’s everyone going to make?! I’m going to cut my wrists and put loads of blood in.
蟹男:
If someone mentally ill made the chocolate, then there will definitely be something weird mixed in with it, and anyway, there’s no point in hand-making chocolates and not putting something unusual in. If a girl’s nails have become short, then that’s not because they were making snacks, it’s because they’re mixing them in with the snacks. Also, if they have more cuts, periods, or stuff like that, then it’s definitely black. Well, not black, but blood.
むてき:
Everyone frustrated because they can’t get any menstrual blood to put in the chocolate because of their menstrual cycle.
あいりちゃん:
Putting your own blood in the Valentine’s chocolate you’re going to give to the boy you like — isn’t that pretty much the norm for us girls?
沙やか:
The spell we had when we were in elementary school was that you’d put your own blood and drip the tears you’d cried at the though of the one you loved into the handmade chocolate, or that you’d knit your own hair into the scarf you made for them — these terrifying things were popular and we did them without a care. I never actually did it, but there are probably witches in every period of history #Valentine’s
蜜乃サナ◆:
Were there ever any girls who didn’t put their own menstrual blood in the Valentine’s chocolate?
蟹山:
I have a friend who’s been traumatised ever since he realised that there was hair inside a Valentine’s chocolate he had already put in his mouth. Guess it’s better than blood, but the poor guy!
美咲@梶裕貴に心臓を捧げる系女子:
They say it’s a Valentine’s spell and stuff, and it seems that they put hair and spit and stuff in there…do they just want to hurt the person they love? Don’t they realise that someone’s going to eat it?
明野貴志:
I saw a tweet that said, if you’re putting something in handmade chocolate, then I recommend blood. Because at least blood has some umami. And now the heart palpitations won’t stop.
王 妃:
Huh? You thought that Valentine’s chocolates didn’t have bodily fluids, blood, or hair in them? Valentine’s Day is when AIDS gets transmitted the most.
まもたん童貞卒業わず:
Valentine’s is scary wwwwwwwwwwwww Like there’d be spit or blood in the chocolate ~wwwwwwwwwwwwwwwww glad I don’t have to worry about that wwwwwwwwwwwwwwwww ain’t no one gonna give me any (^.^)
黐月(りつき):
Just felt a shiver go down my spine at the premonition of there being girls who hand chocoloate with nails or blood or spit in it to the boy they like on Valentine’s.
小野寺ヒカリ@ストフェス参加:
It’s too frightening to put your own blood or hair in Valentine’s chocolates…but seems like there are quite a few people who do…they put spit and stuff…DISGUSTING…
仮縫:
The thing about Valentine’s chocolates is that you’re happy if you get handmade chocolates from someone you’re close to, but if you get handmade chocolates from someone you’re not close to, then it’s scary. You start getting anxious that there might even be poison in them w.
海砂利水魚:
Just thought this, but when girls are making Valentine’s chocolates and stuff, they mix it with a spoon, and then they lick the spoon, so won’t the chocolate you get have at least a little bit of spit mixed in with it?
カミーユ・ビダンの再来:
I’m a bit frightened of handmade chocolate. What am I scared of? — Well, before one actor ate the handmade chocolate sent to him by a fan, he broke it in half and a load of pubes fell out. I’m scared of that kind of thing happening.
あば・レ・うま:
If you mix blood into Valentine’s chocolate then your love will be reciprocated…so scary (-_-;) Still, back in the day, I got some cookies on Valentine’s day, and there were loads of tiny hairs in them…Wonder if that was the same thing…?
