Why Embrace False Utopias?

Why do clever people often become dayglo prats? Not stupid by any means. More foolish and not embarrassed by their recklessness. It’s one thing to be incompetent or ineffectual but that’s not what I’m getting at here. It’s smart people who get carried away with delusional dreams.

How many vocal futurologists have said – “work is dead”? That one day we will be living in an age of leisure and ease because sophisticated machines will have taken all the drudgery out of existence. Intelligent machines doing all the things we once considered to be work.

In essence it’s a utopian vision that stands-up to be knocked down. In fact, the subject matter has been chewed over in science fiction ever since science has played a big part in our lives. Such popular fiction takes us from a dream world to a hideous dystopia that the original dreamers hadn’t envisioned.

The year is 2274. Almost 250-years ahead of where we are. Humanity is living in a bubble. That bit doesn’t change. Most people are unaware of how their society functions. Again, that bit doesn’t change. Rituals and customs dictate the path individuals take in life. Like today.

Strangely, even in the year 1775[1] those three aspects of life were evident. Maybe they are perpetual. However, there’s an exceptional point to make. That’s our rebellious nature.

The year is 2274. The movie is Logan’s Run[2], made at a time when society had ripple of anxiety about the so called “silicon revolution.[3]” That’s 1976. Before the elevated level of interconnection and communication that the INTERNET has afforded us.

It’s a sobering science fiction movie with a somewhat optimistic ending. Looking dated. I can get past the images and props that epitomised the seventies vibe. That’s become vintage.

To me, aspects of the theme of the story come from H. G. Wells. Nothing wrong with taking great ideas and reshaping them for the time. In the end the flawed utopia is defeated by our rebellious nature. Or at least of some people. The seeking of truth, at all costs, and to look behind the mask that everyday life paints.

You may ask – what the hell am I getting at? It’s a reaction to the recent headline[4]:

Musk says that in 20 years, work will be optional, and money will be irrelevant thanks to AI.

I like growing vegetables. Gardening is a superb way of doing something practical, staying grounded and in touch with nature. It’s good for one’s mental health too. However, the notion that work will be optional is far-fetched. The idea that money will disappear in a couple of decades is nuts. That’s not going to happen.

I know that the motivation to say such things maybe merely to provoke. That has its function. Nothing like stimulating a debate about the future. Surely, we are in for some dramatic changes in my later years on the planet. Surely, we need to equip the next generation to deal with these changes. Surely, we need to protect the public interest in turbulent times.

“Prat” is an often-applied British term. There are a lot worse terms than that one.

Navigating Aviation

Each profession has a way of speaking. This is not usual. Just try reading a long-winded contact on any subject. There are lots of references to a “third party” and more than one. Copious uses of the word “herein”. A good sprinkling of “hereby” and “foregoing”.

I don’t speak those words. If I used them in everyday conversation, I’d get locked-up. Nevertheless, these English words are universally applied to common legal documentation. The hundreds of End User License Agreement (EULA) that we all sign up to, whether we know it or not, apply legalese language liberally [love the alliteration].

Aeronautical people are no different. I could have said aviation people or professional flying people. There’s the rub. Even to say the same thing, there are a myriad ways of saying it.

One major problem that we all encounter, now and then, is having to work with a community that uses language in a different way from ourselves. I’m not talking about language as per dictionary definitions of words and standard English grammar. For good or ill, English opens the door to a numerous of ways of saying basically the same thing.

Professional English users, as I have alluded to above, choose their own pathway through the possibilities. English is not alone in facilitating this variability of expression.

I once worked in Bristol. A Filton. A large aircraft factory with an immense heritage. That included the Concorde project. Here both British and French engineers had to work closely together on a huge joint venture. It succeeded. Supersonic flight was commercialised.

One of the delightful little books I picked up from that time was a handy English/French dictionary of aeronautical terms. Those in common usage at an aircraft factory of the 1970s. To communicate effectively it was recognised that technical words needed to be explained.

What I’m noting now is this reality hasn’t gone away. For all the imaginative language Apps that might grace my mobile phone, there’s still a need to explain. This gets even more important when it’s a specific aviation community that is being discussed.

How do people from other communities get what regulatory people are saying when it’s perfectly obvious to them what they are saying? Take a banker or financier that wants to invest in electric aviation because they believe the future points that way. They come across bundles of jargon and precise terms that are not found in everyday conversations. Not to say that the world of money doesn’t have its own langauage.

In aviation there’s not only particular words with detailed meanings but a raft of acronyms. Combinations of words that are easily expressed as a package of letters. Then the short, sweet acronym surpasses the original text.

SMS, POA, DOA, ODA, OEM, TSO, TC, ICA, CofA, SUP, FDM, FAR, CS, NPRM, NPA, AC, AMJ, ACJ, GM and I can go on and on.

Maybe we need a Sub Part – better understanding.

Public Broadcasting Value

It seems to be the season to have a downer on the BBC. As the gloomy light of winter gathers all around. The trees are shedding their leaves and that hunkering down mentality is invading my thoughts. Lawns no longer need mowing. Soden with moss and leaf fall.

I understand the dislike that partisan commercial broadcasters have for publicly funded broadcasters. The question of a “level playing field” and “bias” is always likely to come up.

Making a living from commercial advertising is highly competitive. Demands never stop. Seeking income from a marketplace that rises and falls with fashion and fad. That’s hard. Admittedly, there’s the compensating factor of wealthy benefactors or owners, prepared to make a loss, pumping funds into like minded companies. Shifting sands of political influence.

So, looking across the aisle at a major broadcaster that gets funds from the public, as a matter of law, must seem rather disconcerting. Certainly, it’s the sort of issue the wealthy benefactors or owners of media are going to kick at. Some to the extent of wanting to destroy chartered institutions with an ethos unlike their own.

What is a “level playing field” in the British media landscape? Can there ever be such a thing? That’s not an easy question to address. Shifting sands of public likes and dislikes shape the playing field (sorry about the metaphor overload). What might have been considered as independent, objective and neutral in the 1990s is way different from that now, 30-years on.

The British media landscape is not static, nor should it be so. In the period of three decades digital communication has advances at lightning speed. The sheer diversity of channels of communication has multiplied (even if they do repeat the same messages).

One sign of a healthy debate is the self-flagellation that the BBC often undergoes. As an institution, doesn’t it like to agonise about itself. With good reason considering some of the grave errors it’s made in the past. Supporting presenters whose behaviours have been found to be appallingly bad, and even criminal.

Let’s not tar everyone with the same brush. To be able to make mistakes and then correct them, with a good degree of learning in-between, is a strength. Some partisan commercial broadcasters seem unable to do this with any conviction. They just move on.

A publicly accountable broadcaster has no choice but to stand in the dock and take a reprimand, when appropriate. That’s no reason to shut it down. It’s a reason to make sure lessons are learned and not forgotten.

Doing a simple intuitive cost-benefit analysis. Taking the BBC as an example. What it offers, when it works well, far outweighs the costs. Listing three points, these have significant value: unifying impact of having a trusted national broadcaster, quality, broad base and originality of its output and editorial independence (not selling products or ideology).

Overseas critics may get upset, now and then, but that’s for them to get over. There’s no way such critics should shape the future of the broadcast media in Britain. That would be untenable.

Reinventing Debate

Once upon a time. A wise sage of great age, a not so bright mean-minded troll, a flighty light-headed dreamer and a jobsworth cog in a lumbering bureaucratic machine all met round a table. Bright lights shone on them so they could not see the masses assembled in ranks who had come to gawk at them in their deliberations.

What a strange tale can be told of their troublesome quarrels. To keep the peace, rarely with success, a queen of spades presided over their preordained disorder. Weekly viewers were invited to take a winding decent down the rabbit hole. Rarely was that rabbit hole decked with anything other than predicable hewn earth.

That’s how I think of the BBC’s Question Time in 2025.

Once upon a time. A programme of thoughtful debate, conducted by articulate men and women who wrestled over current affairs, each with a slice of insight however different their perspectives. Painting contrasting visions of the rights and wrongs of the day. Getting to the heart of the matter as their chairperson questioned and tested their opinions. Or so I thought.

Whereas I’d only hide behind the sofa when the Cybermen stomped around on Dr Who, now I desperately search for the TV remote control whenever Question Time is announced.

It’s not that I don’t enjoy debate. Far from it. It’s a wonderful thing to witness, if it’s done well. Honest debate is much needed given the complexities of our world’s trouble. The idea that everyday people question those who make a career of espousing their opinions is undoubtably a sound one. A little slice of accountability is a powerful medicine.

Sadly, a programme format, that was created for black and white TV, lingers on like the ghost of a smartly dressed long-gone presenter. The audience is treated as if they were merely brought in the shout and howl like citizens of Rome, as the lions’ devoir some poor sap. Playing the crowd both at home and in the theatre, the chosen names of the day become as predictable as cabbage butterflies seeking cabbages.

My fantasy would be to have a real-time on-line forum. A virtual and physical place where answers to questions and rational opinions could be sought. No lack of drama but where the focus was on discovery and inquiry. Another dimension that takes account of the new media landscape. That is, providing a civilised and respectful space where, by the end of the show advancing new ideas or changing minds becomes possible.

If regular topical debate just means reinforcing polarisation the rabbit hole will get deeper. Much deeper. All sense of common sense will be lost. A routine of gainsaying each other will thunder on as a pointless parade. Like an ever-darker version of The Prisoner. I’ll switch off.

Wealth and Power

No history buff, need you be. That’s Yoda speak for saying that there are one or two matters that bubble to the surface through human history. Let’s shelve the fact that the sun rises in the morning and sets in the evening. It’s a subject that a whole religion could be based upon.

I could encapsulate the phenomenon in the words: “Let them eat cake”. An example of a stratified society where those people that the top have completely lost sight of the lives lived by the majority. There’s a recognition that others exist but no great empathy or care.

That detachment can be exhibited in signs like gold plated panelling, crystal chandlers bedecking breathtaking halls and spare no expense expressions of power and wealth.

That’s one of my memories of my one visit to Russia. A port of call during a Baltic cruise itinerary. A trip that highlighted fascinating contrasts but shared histories. A good reminder of dramatic events. The Winter Palace in Saint Petersburg[1] is truly stunning. Lavish in every sense. A sign of the last century intense competition between major European powers.

To top a list, the Palace of Versailles[2] is the premier example of draw dropping magnificence. Naturally, these are global statements of power and wealth that are celebrated as part of our common heritage. They are, however, a lesson that history has posted for us to read.

What do both have in common?

Today, Kings and Queens are familiar with that lesson. Possibly apart from a small number who haven’t yet embraced modernity. If I must write it in the minimum number of words, it’s that distance that can grow between those who have great privilege and those who don’t. Then what happens when that becomes truly unstainable.

Revolution is bookmarked in any history book. These are moments, and their consequences are when a break point is reached. Although signs are there in hindsight predicting such events is a fraught with uncertainty. It’s usually thought that the price of destruction and devastation are a dam that keeps thoughts of revolution at bay. Change that happens, as if a dam breaks, are notoriously difficult to predict and cost. Not only that but such thoughts are rarely in the minds of any revolutionaries and their opponents.

Let me be clear. We are no where near a breakpoint in this moment. If I must write something, it’s more about the subtle signs that the direction of travel is not a positive one. Fine to dismiss my point of view as being that of a dyed-in-the-wool liberal. I get that.

It’s the consequences of the concentration of power and wealth that’s concerning. The rise of the global billionaires and their reach beyond national boundaries is of the age. Nation states are no longer the biggest players in the writing of the story of the future. This is not always entirely bad, some are altruistic, but growing economic inequality[3] is bad. Outcomes from situations where inequality exceeds certain limits, that’s not where anyone sane should go.

The Future of Our Shared Values

That’s done. Reflecting on the last nine years. Time to look to the future. There’s no shortage of articles about the past and the present. Huge numbers of column inches crunch every detail of the current twists and turns of public life. Social media vibrates with repeated daily stories.

I watch a rebroadcast of HIGNFY[1] to quickly get the message that a headline is no basis for figuring out where we are going. Moments pass. Yes, there are reoccurring themes. What’s fascinating is that prominent personalities have their moments in the sun, and that they last a fraction of a second (metaphorically). The world moves on.

Yesterday’s scribblings concerned a degree of nostalgia. If only we could go back to some mythical age where current affairs seemed to make sense. Where people cooperated towards a common good. Where conflict was the exception not the rule.

Don’t look back. Don’t look back, too much. It’s a habit of the British to romanticise the past. Having such a colourful past to draw upon there’s always a story to tell. This inclination is at the root of our difficulties. It would be better to set a shared history as a foundation stone rather than always trying to build the same house.

Here in 2025, the world is being reshaped. There’s only so much that can be extrapolated from experience. Like a tsunami there’re changes happening that are unlike anything that has gone before. Early predictions of the benefits of digital technology imagined a borderless world. Information and learning spreading freely to enlighten and educate. So much for that.

It becomes clear that there are steps needed to protect and preserve our values. Enduring values underpinning our culture. They are not immutable. Forces acting at a global scale can, and do, shape how we think about our nation and what binds us together.

Whether we like it or not, many of the forces that shaped the colours on the world map are being played out in the digital sphere. Boundaries, barriers, conflicts, possessions, passions and powerplay are all there. Maybe they are not so visible to the man and woman on the Clapham omnibus, but they are there in abundance. As if we needed any indication, the experience of Jaguar Land Rover[2] and the cyber-attack they are dealing with, is there as a siren light.

I my mind these are not forces to confront in isolation. They do not respect lines on a map. Back to where I started. It’s by working with others, on an international level, that the harmful elements can be addressed.

The European Union (EU) envisions a Digital Single Market. That’s a project to be on-board. It’s essential to have standards that safeguard privacy and data security. Government Ministers who promote a hands-free laissez-faire approach are naive in the extreme. This is a practical field where Britian urgently needs to rebuild relations with its neighbours.

Rebuilding Relations

Here I’ve posted a thousand posts. So, it might be a good time to reflect. It was back in April 2016 that this blog started. The provocation being the then pending UK referendum vote. What was to become Brexit and a long litany of mistakes and missteps.

I’d not long returned to the UK from my time in Germany. I had a what I thought was a reasonable sense of the UK political landscape, only to find I was wrong. Here’s what I wrote:

“It’s the biggest event since the Berlin Wall fell. Yes, not to mince my words the UK referendum on EU membership could change the political landscape for a generation or more. It could be a terrible gamble that erects dark walls all over Europe or it could start a new period of enlightenment within the European project.”

I wasn’t far wrong with that statement. The landscape suffered a landslide. Even though the results of the votes were practically even- evens, for reasons that now seem bizarre the electorate swung in favour of leaving the European Union (EU). If the polls are to be believed, then the overwhelming majority now regret that choice[1].

“I’m firmly convinced that our place is in Europe. We are strong enough, we are clever enough and we are determined enough to make that project work. What a bonus that would be: Expanding a market that covers half a billion people on our doorstep. Guaranteeing that the world sits-up and listens to Europe. Unlocking a diverse creative powerhouse where the UK would thrive.”

My then time arguments were coherent, logical and straightforward. I didn’t know we were entering a phase when such attributes were to decline in importance. Should I have been wiser? With hindsight it’s easy to say that the campaign to remain in the EU was appallingly poor. Even if, at the time, I did wonder if the pomposity of the then UK Prime Minister would play a negative part in the outcome.

“The frightening alternative is to gamble with millions of jobs and invite a plunge into recension. If this happens it’s the younger generation who will pay the price. We should not condemn them to isolation and struggle for reasons of narrow nationalism.”

Oh brother. With something like 4% knocked off the country’s prosperity and a government struggling to finance public services, sadly I was spot on the money.

“I’m not saying the EU is perfect. In fact, I wouldn’t say Westminster or my local council are perfect – far from it. But the EU is a work-in-progress and not a finished project. It’s better for British pragmatism. It’s a two-way street as free movement brings people to these shores who then go home with a positive view of what we have to offer. In the next generation that means more trade and better international relations.”

Having seen at first hand the workings of both the British civil service and the European Commission, British parliamentarians and European ones, I could see a common thread. The foolish notion that escaping into glorious isolation would produce prosperity was nuts.

Here we are in 2025. It would be nice to say that – I wouldn’t start from here – but that’s useless. The thing to do is to reconcile, reaffirm and rebuild relations with Europe.

Why Timely Aviation Safety Reporting Matters

Waiting for accident reports can be frustrating. I’ve found this to be the case in past experiences. When a major fatal aviation accident happens the demand for information is exceptionally high. That means that every credible source of information will be drawn upon.

I don’t think anyone expects professional aviation accident investigators to come up with instant answers. Extensive and meticulous work is required to arrive at detailed findings. When it’s possible accident investigators publish interim reports to ensure that relevant information becomes generally available.

Countering this reality is the need to ensure that the aviation system is not operating at elevated risk during the period that investigation is being conducted. Information needs to flow to those who are empowered to take corrective action.

Given the nature of international civil aviation, accidents can occur anywhere at any time. There’s no rule, statistical or otherwise, that can stop these extremely rare events occurring. Much as it’s fine to promote an ambition for zero accidents, it’s not going to happen.

The frustration I’ve pointed to is shared by industry and authorities. As time goes by the level of speculation and misinformation always increases where there is an absence of verifiable facts. There’s always a need for industry, authorities and investigators to cooperate. As often each one will have a part of the jigsaw that when put together describes what happened.

For all sorts of reasons, this necessary cooperation does not always exist or exist as a smooth pathway to resolving a situation and initiating corrective action. Where barriers exist and delays accumulate the collective aim of assuring aviation safety is harmed.

The International Air Transport Association (IATA), at their recent conference, highlighted this as being a significant issue[1]. There are international standards, but these standards are not always applied in the manner with which they were intended. It seems obvious to say. It’s essential to learn safety lessons and take corrective action as soon as it’s humanly possible.

Where sufficient resources are an issue then there must be cooperative arrangement to allow others to help. It’s by sharing expertise and equipment that the time between occurrence of an event and the implementation of risk reduction measures can be reduced.

Risk reduction measures do not always need to be the final measure. There are the conventional strategies for addressing aviation safety risk – reduce, eliminate or mitigate. Even if publication of a final accident report is a year or more away, there’s often much that can be done in the interim.

Bureaucratic protocols, political sensitivities and commercial interests are real. However, most governments have signed up to obligations within the ICAO convention and its standards. It’s recognised that timeliness is vital.

Recent Aviation Accidents: Lessons Learned, or not

I start from a position of apprehension. Making aviation accidents, documentary style, the subject of a television series does give me some concern. Obviously, there’s the importance of being respectful to those involved. To reveal something that is of genuine public interest.

Accident investigation and journalism seek to answer the six questions – Who, what, where, when, why and how. When it comes to addressing aviation accidents that have occurred in the last 18-months some of the process of investigation may still be ongoing.

My apprehension starts with – what is the purpose of the series? Does it go some way to answering the question – why? That’s especially the case given that word is in the title[1]. Practically the “why” is turned into a probable cause because the “why” can include multiple factors. It’s rare for there to be a lone factor that results in a tragic outcome.

Broadcast last night by the BBC, this series took a selection of the accidents that recently commanded international headlines. The fatal events have been much discussed within informed professional communities and across social media. I’ve written on them too.

[Fatal Boeing 737 Crash in South Korea, Investigating the Black Hawk and American Eagle Collision, Aircraft Safety and Fuel Starvation, Understanding Boeing 787 Avionics.]

We do this to seek to understand. If there are always lessons to be learned, it’s imperative that those lessons be learned without delay. Lack of an informed and timely response exposes the flying public to further risks.

Sadly, a few of the lessons learned in the past have not been translated into change. The fatal accident at Muan International Airport in South Korea is a case in point. Brid strikes are not new. The dangers of flocking birds have been highlighted time and time again. Whilst airports are built near large bodies of water this will continue be a risk. However, it wouldn’t be right to say this is the only cause of the accident outcome at Muan.

Truly tragic are what may be called: avoidable accidents. This is where the event is purely made up of human actions that need not have take the course they took. Processes and procedures were inadequate, and known to be inadequate, for the situation. To me, this is the case of the military helicopter that collided at low altitude with a passenger flight in Washington DC. It’s mystifying as to why past occurrences of near misses didn’t prompt a change to operations.

I’ll say this because it’s not often given credit. A testament to the good design of an aircraft, and the extensive certification work done and the rigorous training of crews, an accident in the Canadian snow did not become fatal. Upon a spectacular heavy landing in Toronto everyone escaped.

On take-off, a London bound, fully loaded Air India Boeing 787 failed to climb. The results were catastrophic in every sense. Not only were all on-board killed but there were multiple fatalities on the ground.  This tragic fatal accident remains mysterious. The published preliminary report is a source of more questions than answers. Facts so far published do not explain the sequence of events.

What connects this spate of aviation disasters? Nothing, that I can determine. Although, there is the importance of lessons learned. They are not that compilation of dusty past accident reports that sit on a shelf. They are a source of everyday learning. That is learning that needs to be put into action. Timely action. Not waiting for a final publication.

Music to Dance Under the Moon

Flicking through the vinyl albums that no one wants there’s one I should have rescued this week. In a corner, charity shops usually have a pile of gifted vinyl records. I like to look for a hidden gem. Unfortunately, what’s left is the tatty and practically valueless disks. Versions of musicals that have fallen out of fashion, scratched classical concerts and embarrassing compilations.

It’s harvest time. Autumn is undeniable. A colourful carpet of leaves litters the pavements. Remarkably warm. Monday’s blue skies set of the spectacle of the trees display. When the October weather is like this there’s not much to complain about. Crisp walks through the dappled light as the low sun’s rays shine through the branches. Good to be alive.

Looking out of the window in the early morning it was as if it was a spooky daytime. In a monochrome light the outline of the tree line was like a cutout silhouette. Nothing could move without being seen. Grass glittered. Hedges stood like army ranks. All because of the intensity of the moonlight. Constant in the cool air.

The pop tune that entered my head was there for the taking but I’d left it to one side. This is a song that resonated from my boyhood. Some might cringe a bit. Let’s suspend judgement and let the 1970s be the 1970s. “Under the moon of love” is about as catchy as it gets. Showaddywaddy[1] dressed up in their brightly coloured exaggerated 1950s garb. They were not the only ones to do that for Top of the Pops. What’s memorable is the danceability of their pop classics. It makes me want to move. Don’t tell anybody. Sadly, my long hair has long gone.

It’s the time of the harvest moon. So, it’s a time for moon tunes. Not just any moon but the first supermoon of the year will grace the sky tonight, Tuesday 7th October. This bright full moon of 2025 will light up the nighttime. It will not have a musical accompaniment in my garden even if there’s a lot to choose from. The neighbours wouldn’t like it.

The best of the pile is Neil Young and his Harvest Moon[2]. 180 degrees from the Showaddywaddy pop effort. Neil scores top rating. It’s melodic, melancholy and memorable. Fantastic. Just right for a quite evening gazing at the moon overhead.

On a melodic theme the next one I’d recommend is from Nick Drake[3]. Again, it’s the 1970s that provides the music. It was a decade of variety, to say the least. Song writers were pushing the boat out and coming up with magical results.

And here’s another. Another to dance to in the moonlight. Moondance in fact. Van Morrison[4] this time. Perfect for an October night.

And if anyone has ever doubted the genius of Beethoven there’s the Moonlight Sonata.

The coming night will mark the start of a run of 3 supermoons. November and December will be graced with magical moons. I hope that’s an omen for good. Love and happiness.
