Fatal Boeing 737 Crash in South Korea

Jeju Air Flight 7C2216, arriving from the Thai capital of Bangkok, at South Korea’s Muan Airport (MWX), crashed at around 9am local time (00:00 GMT/UTC) on Sunday, 29 December 2024.

My condolences to the families and loved ones of those who died or were injured in this fatal aircraft accident.

Pictures of the Jeju Air Boeing 737-800 landing[1] show that no landing gear can be seen deployed. A video image shows the aircraft skidding down the runway at high speed. The aircraft is wings level. It is reported the aircraft overrunning the runway and colliding with a wall or ramp. The video image does suggest that the aircraft engine thrust reversers were deployed. This is wrong. Weight on wheels is needed for deployment.

MWX runway 19 has a Landing Distance Available (LDA) of 2800 m. The local visibility was reported as 9000m and the wind speed at 2kt.

Was the pilot in command trying to go around? The accident flight recordings should answer this question. That is from the aircraft Flight Data Recorder (FDR) and Cockpit Voice Recorder (CVR).

This remains a hope. Reports are that the FDR has been damaged. This should not be a surprise given the nature of the impact it suffered. However, both FDR and CVR are designed and tested to survive extreme cases.

The South Korean Ministry of Land, Infrastructure and Transport says that the accident flight and voice recorders have been recovered[2].

Jeju Air is a popular South Korean low-cost airline. The airline was established in 2005.

A full independent accident investigation will no doubt take place. That is in accordance with the standards and recommended practices of ICAO Annex 13.

Current media speculation surrounding possible causes of this Boeing 737 accident do not offer any satisfactory explanation for the sequence of events. For example, it would be astonishing if the root cause of the accident was a bird strike or multiple bird strike shortly before landing. The aircraft has several means to deploy its main undercarriage.

It is likely that safety culture, controller and pilot training, and airport facilities are bigger factors in this fatal accident than the fact that it involved the loss of a Boeing 737-800 aircraft.

NOTE: Boeing 737 “If the gear fails to extend properly or hydraulic system A is lost, the gear can be manually extended by pulling the manual gear extension handles, located in the flight deck.” Landing Gear

POST: The impact test in the applicable technical standards EUROCAE ED55 (FDR) and ED56A (CVR) are demanding. The recorder’s crash protected memory module is fired out of a canon into a shaped target to simulate an accident scenario. It must be readable afterwards.

SONAR in Ocean Wreckage Recovery

Finding aircraft wreckage in the deep ocean is possible. However, it requires a degree of good fortune. Most of all, it requires the searcher to look in the right places. Lots of other factors come into play, particularly if the ocean floor is uneven or mountainous.

The primary tool for imaging the ocean floor is SONAR. That’s using the propagation of sound in water. SONAR can be of two types. One is called “passive” and the other called “active”.

The first case is like using a microphone to listen to what’s going on around. Of course, the device used is named appropriately: a hydrophone. It’s a device tuned to work in water and not air. Afterall, sound travels much faster in a liquid than it does in air.

Passive SONAR depends on the object of interest making a noise. Just like we have directional microphones so we can have directional hydrophones.

Passive SONAR is only useful if the aircraft wreckage is making a noise. Since in the case of Flight MH370, the battery powered underwater location beacons attached to the accident flight recorders have long since stopped working this kind of SONAR isn’t going to be much use.

Active SONAR is analogous to RADAR. That is where a pulse of high frequency sound is sent out through a body of water. Then sensitive hydrophones pick up a reflection of that pulse. It is detected and all sorts of miraculous digital signal processing is done with the acoustic signal, and an image is then formed. From that displayed image the human eye or sophisticated algorithms can make sense of what they are looking at on the sea floor.

Active SONAR can give both range and bearing (direction). Timing the sound pluses from their transmission to reception can give a way of calculating range. Or distance from the object providing a reflection. Bats know how to do this as they navigate the dark.

In sea water, there are complications. Sound does not always travel in a straight line in sea water. The speed of sound in water depends on salinity, temperature and pressure. All three of these factors can be measured and compensated for in the SONAR signal processing that I mentioned above. Helpfully at ocean depths beyond a kilometre the calculations become easier.

The average depth of the Indian Ocean is over 3 kilometres. It’s mountainous underwater too. So, what are the chances of finding flight MH370 on the ocean floor after 10-years[1]? This prospect goes back to my earlier comment. It requires the searcher to look in the right places.

Just imagine encountering the Grand Canyon for the first time. It’s nighttime. An important object is lost in the canyon. You only have the vaguest theories as to where the object has come to rest. With a handheld touch you go out to search. What are the chances of finding the object?

There are several factors that are in your favour. One, you know what the object might look like or, at least, in part. Two, the easy search locations (flat/smooth) may be covered relatively quickly. Three, certain areas of the rocky canyon have already been searched. Still the odds are against finding the lost object without a high degree of good fortune. 

I wish the new planned searchers much good future[2].

NOTE 1: one of my student apprentice projects was to design and build a Sing-Around Velocimeter for use in relatively shallow sea water[3]. It worked but was cumbersome in comparison with the simple throw away devices used for temperature depth profiling.

NOTE 2: To get down to the ocean depths required it’s a side-scan sonar that may be used. This active sonar system consists of a towed transducer array that can be set to work at different depths. Imaging objects on the seafloor and underwater terrain is done as a towed array moves slowly forward through the water. The scanning part is the acoustic beam sweeps left and right. Each scan builds up part of an image.

In operation, as the frequency of the sound in water goes up so does the resolution of a potential image but, at the same time, the range of the sonar system goes down. Thus, a sonar system used for surveying may have low and high frequency settings. Unlike sound in air, here high frequency means above 500kHz.

NOTE 3: What will an aircraft accident recorder look like after a decade in the deep ocean? It might have survived well given the nature of the dark cold pressured environment. This picture is of an accident recorder recovered from relatively shallow sea water (Swiss Air Flight 111).

Risks of Pruning Government

Everybody likes a good analogy. I don’t know if this one qualifies. We communicate by saying this thing is like this other thing. The first one being easier to understand than the one second. It’s a basic part of storytelling.

Who understands how government and its institutions grow? I’ve no doubt there are huge textbooks full of detailed analysis and complicated theories. Sitting on dusty library shelves. Written by knowledgeable and venerable academics.

I’m coming from a background that’s more practical. One of having mixed with and worked in bureaucratic structures built to serve a public good. Bureaucracies that have both traditional administrative and technical elements.

Here goes. Government, or rather the administrations, institutions and services are like a large oak tree. It’s kind of human pyramid in the sense that there’s a top and bottom. An upside-down tree minus the roots.

Oak trees are long lived. They have branches that are substantial so that they can carry a heavy load and suffer the battering of the wind and rain. Out on the furthest limbs they are young, spindly and vulnerable.

Today’s media is full of stories of what might come. There’s a new year in prospect. Across the Atlantic a new President is about to take-up office. Speculation is rife. One part of that speculation concerns the future of the large administration that is the federal state.

The Presidents favourite billionaire has ideas to take a chainsaw to the tree of administration. Generally speaking, a chainsaw isn’t the best tool for the job, but it certainly is scary. Maybe that’s the point. Keeping a huge, embedded administration on its toes.

My point, and I have one, which is more than I can say for Rory Stewart, a former minister, talking on the BBC this morning. My point is that pruning a tree requires the pruner to be competent. That’s having the attitude, skill and experience needed to make a good job of it.

Lopping off limbs of a working administration with the sole aim of saving money isn’t such a sound idea. Each branch has a purpose. It’s as well to have a comprehensive understanding of what that purpose is before the pruning starts. From that understanding can come a sound reason to prune.

Ideally, pruning should be good for the tree and good for everyone who depends upon it. Weak branches that suck-up energy even though their days are numbered should become firewood. Fledgling young branches that are heading out to explore new territory may need encouragement and support.

So, it is with government. There’s a lot of truth in Parkinson’s Law[1]. He knew a thing or two about bureaucracies. The clever bit is finding out where this phenomenon has taken off. Where the tree has grown way out of balance.

Will Musk be competent in pruning? Who knows. One thing is for sure. The potential for loping off a branch that is vital to health, wealth and happiness is all too real. Let’s watch and see.

MH370 and MH17: A Decade On

The unthinkable happened in 2014. One major international airline suffered two catastrophic accidents. These tragic events ran contrary to all the trends in historic aircraft accident data.

In March, flight MH370 disappeared. In July, flight MH17 was shot down. In both cases there were no survivors from these international flights. This remains an unprecedented situation. It is a sobering consideration that such dreadful events were possible in a mature international framework of civil aircraft operations and regulation.

A decade on the pain of those who lost friends, family and colleagues in these tragedies is not diminished. Aviation should not lessen its attention to discovering more about what happened and putting measure in place to prevent reoccurrence of these events.

These two aviation catastrophes are different in respect of causal factors. One remains a mystery but, from what is known, has the hallmarks of an operational accident. The other is undoubtably an aggressive malicious act. Failings in the two elements of aviation safety and security, often viewed separately, are both capable of catastrophic outcomes.

Malaysia Airlines was a State-owned airline in the traditional model. There’s no reason to suppose that the airline harboured deficiencies that led directly to the two fatal accidents. In hindsight, the question is often asked: could both accidents have been avoided?

The extensive underwater search for MH370, in the southern Indian Ocean, resulted in no findings. However, floating debris from the fateful Boeing 777-200ER was discovered. Unlike what happened with Air France Flight 447 were the installed accident flight recorders were recovered from the deep ocean, there has been no such good fortune in respect of MH370.

Accident flight recorders are one of the primary tools for accident investigators. Installed recorders are built and tested to withstand extreme conditions. The reasonable assumption being that they will be found with any aircraft wreckage. The accident of MH370, is one where a deployable recorder may have been beneficial. That is one that ejects from an aircraft when it is subject to the high impact of the sea surface and then floats, possibly away from an accident site. There is a good case to be made for installing both deployable and installed recorders[1]. Particularly a case for long-range international overwater aircraft operations.

The facts surrounding the criminal act of shooting down of flight MH17 are well established. Sadly, in a troubled world it is impossible to say that such malicious acts will never occur again. What is to be done? Avoidance is by far the optimal approach. Commercial flying over warzones, where heavy weapons are known to be used, is extremely foolish. Now, it is good that much more flight planning attention is paid to understanding where conflict zones exist[2].

NOTE 1: On 07 March 2014 at 1642 UTC1 [0042 MYT, 08 March 2014], a Malaysia Airlines (MAS) Flight MH370, a Beijing-bound international scheduled passenger flight, departed from KL International Airport [KLIA] with a total of 239 persons on board (227 passengers and 12 crew). The aircraft was a Boeing 777-200ER, registered as 9M-MRO.

NOTE 2: On 17 July 2014, at 13:20 (15:20 CET) a Boeing 777-200 with the Malaysia Airlines nationality and registration mark 9M-MRD disappeared to the west of the TAMAK air navigation waypoint in Ukraine. All 298 persons on-bard lost their lives.

Level Playing Field

The back-office work of campaigning does take advantage of a lot of volunteering. That’s my experience. Giving time and energy for free and seeking to advance a worthwhile cause.

It would be nice if all political parties in this country where wholly supported by a membership that is both engaged in activities and willing to put their hands in their pockets, now and then. The reality is that, of all the eligible voters in this country, only a small fraction of them is committed enough to be a member of a recognised political party.

Even with a strong membership and a well-motivated bunch of volunteers, life is hard going unless there is a reasonable sized war chest to support campaigning work.

Come election time the range and breadth of communications that is necessary to be a competitive candidate is considerable. Thus, it is no surprise that history can turn on who has the most resources. That doesn’t always work but without a spending capacity rivals have most of the advantages.

Politicians seek the patronage of the wealthy as a pathway to power. We can remain pure and get engaged in arguments both ethical and moral as to the impact of patronage. Or we can accept that it is inevitable and ensure that strict rules exist to create a reasonably level playing field for all candidates. Since we can no more stop influence from flowing from one person to another than we can freeze gravity then a democratic society cannot must not have woolly rules on these matters.

Talk now is about financial donations that originate from abroad. That is when a wealthy person wishes to funnel money into a political party in a country other than the one of their citizenship. No prizes for guessing who or what this is about.

Now, I could say only UK citizens should be allowed to donate to UK political parties or organisations. Foreigners should be banned from involvement in national democratic processes. Trouble is that this subject is not so cut and dry as it might first seem.

Those with dual citizenships may wish to contribute and participate. That sounds reasonable. Those with notable family ties may wish to contribute and participate. Certainly, there are reasonable cases to consider. What’s interesting here is the legitimacy of the interest and that it is of a “friendly” nature.

I’d like to go back to the mater of the level playing field. If a candidate meets the criteria set down for a given election, then the battle should be over achievements, ideas and policies and not over the size of bank balances. Financial donors should not be able to exert undue influence by throwing money at a campaign. That’s where there is a strong need for strict financial limits on donations or any form of beneficial contribution that comes from abroad.

Societal Change and AI

Societal change is inevitable. It seems hack to analogise with reference to the printing press. Look what happened, an explosion of communication. Dominance of the book for centuries. Expanding literacy. Progressive shaping of society resulting in this era.

We are only where we are because we stand on the shoulders of the giants who went before[1]. Not just the giants. There is massive amount of human contribution that is never accounted. The unseen heroes and the occasionally rediscovered thinkers and doers.

Along the way of history those who battle the battle of glass half full or glass half empty chatter away. We are either in a glorious age or a minute away from Armageddon. Polar ends of our future, both stories have merit. Who has a crystal ball that works?

I’ve been aware of neural-networks and joked about Bayesian Belief Networks for at least two decades. Having been involved in the business of data analysis that’s no surprise. Even so the rapid advance of a multitude of different forms of artificial intelligence (AI) is a surprise.

Talking generally, we have this foolish mental picture of the world that everything is linear. Progression from one state to another takes proportionate steps forward. It’s a hangover from the analogue world which is where we were until the 1960s/70s.

This fetish for straight lines and normal curves is deeply embedded. It’s odd. Although a lot of rules in nature do have a linear form, one that Sir Isaac Newton would recognise, there’s far more that follows other rules.

In the last few weeks this fetish played out at a global scale. We are all treating climate change as if it’s a water clock. Drip, drip by drip the climate changes. A reaction to a progressive degradation. Yet, environmental reality might have a step change in degradation ahead.

In my view it’s right to try to vision ahead about the path AI technology might take. It’s right to consider more than progressive development and evolutionary change. Information systems have a habit of either falling into disuse or marching on at the pace of Moore’s law[2].

Another example. The math of Fourier transforms has been around a long time. Doing Fast Fourier Transform (FFT) in the 1970s required a couple of chunky cabinet full of power-hungry electronics. For the few, not the many. Today, every smart phone[3] in the world can crunch FFT algorithms. For the many, not the few.

Can we use a simple graphical representation to say where AI is going[4]? Will “intelligence” double every year or two? Well, I suspect that developments will go faster than a doubling. Like Moore’s law these conditions tend to become self-fulfilling. It’s a technological race.

[Why? To a machine there’s no sleep. To a machine there’s 86,400 seconds in a day. Everyone is meaningful and useful. To a complete and successful electronic machine only a tiny fraction of its operating time needs to be spent fixing itself. Or that might be one job left to us.]

Labour’s IHT Policy: A Threat to Family Farms?

Labour is driving down a road it’s driven before. It’s a shame when the two biggest political parties in Britain are so captured by their past that they can no more look forward than a duck can master arithmetic.

Post Second World War the country was broke. Rising taxes were inevitable to pay down debt. The British State was far more directly involved in everyday economic decisions than it is now.

Inheritance Tax (IHT) got its status as a loathed tax partially because of the necessary actions of the post-1945 Government. At that time, “estate duty” was increased to 80%. This generated increase tax revenue but led to the breakup of large country estates up and down Britain. Ironically, the breakup of country estates created an opportunity for some tenant farmers. As the estates were sold off in lots so tenants could become owners, if they could raise the finance.

So, you might say farmers paying IHT at 20% isn’t so bad by comparison. The amount of generated increase tax revenue isn’t much. With one hand the Government is subsidising farmers and with the other hand it’s taking a cut of their lifetime acquired assets.

Another side of the coin is the cost-of-living crisis. Certainly, winter heating costs have been a matter of great concern for a lot of people. Food too is an absolutely essential expense. Hence, the growth of food banks in every part of the country. This shouldn’t be accepted as the norm.

All of this is happening at a time when the nation’s supermarkets are making healthy profits. Keeping cheap food on the shelves with, in some cases, the philosophy of sell it cheap and pile it high. Industrialised and highly processed food coming in at the lowest prices to the customer. At the other end of the supply chain, forcing down farm gate prices.

You would think that getting national food production, the job done by farmers, right would be an imperative for Government. You would think that a regular dialogue with farmers might be quite important. Wouldn’t you?

The problem with Labour’s 20% IHT and the threshold of 1 million is that it’s not going to have much impact of those who own large country estates to avoid other taxes, like CGT. It’s not going to have much impact on large corporate agricultural enterprises. It may not even have much overall impact on land prices. Afterall, they don’t make it anymore.

But it’s going to clobber small and medium sized enterprises, very often family farms. It will clobber far more than the Treasury’s last-minute calculations say[1]. The reason is clear. The profitability of family farming has been dire over recent years. Add a new tax bill and selling-up will be the most attractive option for many potential next generation farmers.

Then the question must be asked what’s it all about? What are the values underpinning this policy? There I go back to the start. Does Labour perceive these working people as “rich”. Their logic may go, why shouldn’t the rich pay more after the Conservative Government that they supported has made such a mess of the country? One way of seeing where we are.

Trouble is that they have aimed at the wrong target.

Ignoring Climate Change?

In a way, I’m not immune from a little hypocrisy. Petrol prices go up and I’m not going to jump for joy. Prices go down. I’m not suddenly thinking that’s just going to encourage more consumption. No, I’m looking at the pound in my pocket. It will cost me less to fill up the tank.

There was a whole swath of apocalyptic tales of the world in the 1970s. The “oil crisis” of 1973 should have been a warning. Humanity might have taken the opportunity to look at the trends related to oil and gas consumption. There might have been a more sustained reaction.

Instead, alternative lifestyles, renewable energy projects and energy conservation were thought of as quaint novelties or scientific curiosities that would never really catch on. The political addiction to short-termism overrode consideration of substantial change. Increased exploration led to new sources of oil and gas being found.

Today, we should know better. The fight against climate change has a decade of talk behind it. Humanity knows that the link exists between burning hydrocarbon and a changing global climate. We are ignorant no more. Now, I almost wish I hadn’t written that last sentence.

Across the pond there’s a powerful nation. One that influences the behaviour of 100s of other nations. The US is the largest producer of oil and gas in the world. However, until the last few weeks it had recognised that maybe that isn’t a good formula for the future.

Back to that dollar in the pocket. Despite the US being a powerful nation many its people didn’t feel that way. All politics is local. When filling up with gas gets more expensive people do not jump for joy. In fact, there’s that human tendance to romanticise the past and remember when everything was cheaper. Life was easier. Can’t we go back?

It’s being reported that US President elect Trump’s choice for energy secretary is going to be like turning the clocks back. Prospect is that the fight against climate change is going to get a back seat. At least for the next 4-years.

Does this spell global disaster? Well, it certainly is a great big lost opportunity. Just like here in the UK, Brexit ignited the tendance to romanticise the past. It looks as if the same phenomena have taken root in the US. Burning more and more hydrocarbons is like a sugar rush. A boom to begin then followed by exhaustion. I expect after this presidential term the results will be one of regret. Just like Brexit. A wonderment – why on earth did we do that?

Still, there’s an opportunity for other countries to race ahead with advanced and alternative technologies to reduce energy dependency. It’s hard to think and act long-term. I’m confident it can be done. If it’s done successfully the prize will be great.

New Form of Monarchy in 2024?

An observation. There’s something strange going on across the Atlantic. You see, I have found inspiration in the story of America’s revolutionary struggle. The writings of Thomas Paine stirring up a radical movement. The strong desire to be independent of the rule of Kings and Queens. There’s a lot to be said for freeing a nation from imperial tyranny.

The Declaration of Independence in 1776 is a bold statement. Rejecting the royal authority of George III to set a new nation on an independent path. It proved to be a dynamic and prosperous democratic path. One that people across the world looked on with admiration.

It’s true that the United States has had its own dynasties. Powerful families and influential individuals that have shaped its history. However, since its independence, none of them have ruled as a monarch. None have wheeled massive power without checks and balances.

Yet here we are in 2024, and a form of pseudo monarch stands ready to take the reigns of power. Sure, democracy has played its part in putting one man in control. That, in of itself, is not unknown in the history books. The question to ask is when does a Republic tip over and become something quite different from what it has been?

I hope my observations are an exaggeration. It’s all to easy to see the News that commentators want us to see. I’ve often found that it’s most difficult to see things as they actual are as opposed to how they are shaped by personal beliefs and fleeting desires. Objectivity isn’t so easy.

This much can be said, the next four years are going to be turbulent ones. There’s a certainty in that conclusion. Even with the Atlantic in the way, just as the Jetstream brings us changeable weather, so unsettling waves of transformation will hit our shores.

The latest commentary coming from supporters of the new Trump regium in the US is one of polarisation. It’s the traditional stick-up. Choose between us and them. Our populous island off the shore of continental Europe must be squeezed into a choice between the US and the EU.

This monosyllabic way of framing a debate gets swallowed by the media. Overall, it’s nonsense. There’s no way that both will not be important for as far over the horizon as anyone can see. Both are going through periods of disruption. For once, domestically, the UK seems relatively stable. That’s putting aside the past damage done by Brexit and a Conservative government that fell into total disrepair. Yes, the UK can plot its path knowing that some internal consistency can be expected.

Everything I’ve written here is overshadowed by issues of global concern. Overshadowed being the sad reality. Climate change will not wait for the dust to settle from ardent disruptors. The planet’s atmosphere knows nothing of the exploits of prominent personalities. We desperately need to rediscover common interests and act on common concerns.

Budgets

You can’t live with them, and you can’t live without them. That’s budgets. Most of us budget even if we don’t write it down. I’ve got a certain amount in my bank account. If I spend more than is stamped at the end of my statement, then trouble may ensure. Not always given our modern dependency on credit. A problem arises only when spending gets out of control.

Mr Micawber cautioned about debt’s downside: “Annual income twenty pounds, annual expenditure nineteen and six, result happiness. Annual income twenty pounds, annual expenditure twenty-pound and six, result misery.” In his time, Charles Dickens was acutely aware of what unsustainable debt could do to people.

We’ve had weeks where the news media has created a landslide of content on a budget. The repetition of point scoring has got tedious. It’s way out of normal everyday human experience. I don’t know about you, but I can’t easily relate to a number like £1,226 billion[1]. Every year public expenditure totals numbers of that order. It happens. It’s real.

Today, our UK “billion” is a thousand million. That’s spelled out as a one followed by nine noughts. At one time in the past the UK “billion” meant a million million. That’s spelled out as a one followed by twelve noughts. That got dropped for the sake of international harmony.

I have used such numbers in lectures on aviation safety. To think, I often got people glazing over when I talked about ten to the minus nine per flight hour. That’s a billionth of something. A mighty small number. In these cases, a number denoting a probability of something happening.

So, here we are in October getting excited over a change of couple of hundredth of typical annual national expenditure. Not without reason. That figure sound like a small number, and it would be, if it wasn’t for the subject Dickens raises, namely debt.

Wisdom comes from learning from experience. Lessons learned are incredibly valuable. That’s not rocket science. Only we need to factor in how easily we forget bad experiences.

In terms of budgeting, recently two reckless politicians taught us a lot[2]. Truss and Kwarteng sound like a comedy double act or a dodgy back street lawyers office. Those two monster brains had the marvellous idea of borrowing more to give it away. In a short flash of genius what they did increased borrowing costs and spooked just about everyone.

Debt matters. Nation States are not like people, so the home economics analogies don’t stand up. However, borrow too much without being absolutely clear as to the answer for question like – who, what, where, when, why and how and the results are likely to be extremely unpleasant.

Let’s see if the day ends with a pint of beer being more expensive or not. Love them or hate them, budgets are not going away anytime soon.
