Autumn’s Arrival

It’s the season of mellow fruitfulness. Hey, I didn’t even know I was quoting Keats with that apt short line. It’s so embedded in my thoughts.

Season of mists and mellow fruitfulness,

Close bosom-friend of the maturing Sun;

Conspiring with him how to load and bless

With fruit the vines that round the thatch-eves run;[1]

It’s so appropriate to the day. To the week. We are in that spot of the year that marks a transition. Summer is behind us. The ground is covered with acorns and conkers. Leaves are contemplating the end of the duties. A mist hangs over the grass in the early hours.

Just to be clear, I don’t live in a picture box thatched cottage in some hidden English valley. That said, from one long-standing vine, this year, I’ve collected a mass of grapes. This vine, being so deep rooted, it hasn’t suffered the desert like conditions that prevailed for weeks.

Autumn can be a wonderful season. For a few weeks the siren sound of the winter’s coming is held in suspension. There’s time to think about whether to turn on the heating or not as the temperature dips at night.

Transitions are political too. In Britain, it’s the season of conferences. A time for the faithful to gather and spend a few days running around like headless chickens. A harvest of policy papers and last-minute speeches. Condemnation of opponents. Accolades for friends and good company. Tee-shirts, hats and posters plying slogans old and new.

It’s difficult to explain. Might seem tiresome to those who have never spent 4-5 days at the seaside in September but mostly indoors or waving banners in the sea breeze. This week the Sun has blessed all concerned. Those of us who went to the south coast to share time with family and those who went to change the world.

For the party of government, they may be asking:

Where are the songs of spring? Ay, Where are they?

The optimism of last year has dramatically subsided. Now, they seem like the Mars company marketing gurus who rebranded the Marathon chocolate bar to Snickers[2]. A lesson in how to cause confusion for no material gain. Labour’s problem is clear. The chocolate bar is a good national trend indicator. Off the shelf, the bars are smaller, but you pay the same price or more for the pleasure. Arresting decline is proving to be difficult.

And gathering swallows twitter in the skies.

For those who may wonder at this line, Keats didn’t have social media.

[An Aside: AI, and its unsolicited interventions, can be right plonkers. It suggested that I change the grammar of Keats poem. It offered to rewrite the lines above. So, billionaires are spending billions trying to prompt us to rewrite romantic poetry. What a mad mad world.]

A Critical Look at Clowns

There’s a section of British politics which will aways be clownish. I mean this in both a childish sense and a terrifying sense. There are plenty examples of mighty frightening clowns. The Joker was transformed from a comic book TV series of Batman into a menacing movie villain[1]. These are people who embrace a life of deception and chaos. It’s a streak of putting two fingers up to the “establishment”. At the same time making a healthy living from the populous. Milking every moment to advantage.

Having a beguiling nature sustains their success. I’m tempted to think of Peter Cook as the Devil[2] in the 1960s film Bedazzled. Dated as it is, the core theme remains ever relevant. Please protect me from what I want.

Often, clowns are figures of the establishment who have flipped. Driven by a sense of injustice, that somehow society doesn’t appreciate their great talents. Sadly, for them, the seeds of their own destruction are often sitting there waiting to germinate.

It could be said that former Prime Minister (PM) Boris Johnson was a master example. Although I’d not go quite as far as to equate him with Beelzebub. There’s a man who should have stuck to his first profession – journalism.

[Why is it that journalists, lawyers and management consultants aspire to be in Parliament so much? Is it the number one aspiration for societal archetypes – to reach for this pinnacle?].

This week, the media has reveled over a predicable political circus. Now, after having seen the Brexit Party, and alike, fade into nothingness, the UK has a new set of party clowns called Reform. It’s a troupe of escapees from the awkward right-wing of the political spectrum. They are complemented by a small group who claim commercial expertise to bolster their image.

As the tired and elderly Tory Party (Conservative Party) slowly decays and melts away, so this new bunch springs up to try to replace them in full. They have been called populist. In my mind a silly word to use as a general description. Since just about every politician, to a degree, is populist. Whatever the principals involved, few politicians stand at complete odds with the public. If they do, then their time in office can be cut short.

Watching and listening to the new parade of clowns at conference, it makes me wish for a minor revival of the traditional Conservative Party. There was a time when old fashioned social liberals and concerned environmentalists could be found in that British political party. Not anymore.

If I had seven wishes, one of the would be that competence and substance got more attention than loud mouths and false promises. I don’t suppose that’s on offer. Even if it was, I’d need to be careful what I truly wished for because I might just get it. Good advice for anyone. Imperfection is OK.

POST 1: When a Party leader admits his infant Party has no idea how to function in Government. Saying that defecting and discredited former ministers will fill the gap, trouble is ahead whatever happens. Satire is dead because real life has jumped the shark.

POST 2: UK Reform activists sing “God Save the Queen” at the Reform conference. The UK hasn’t had a Queen for almost 3-years. These people are happy to show-off as phony patriots.

POST 3: UK media fascination with sensationalism has given Reform an undeserving boost. The BBC has been ticked off for sacrificing impartiality in chasing this circus. Especially pertinent considering that Parliament contains 72 Liberal Democrat MPs and only 4 Reform MPs.

The Greasy Pole

I think we should be indebted to the writers of “Yes Minister.” And the brilliance of Paul Eddington, Nigel Hawthorne, and Derek Fowlds[1]. No mobile phones, lap-tops or tablets, wood panelled offices, a Minister with all the backbone of a jellyfish and the cunning and mountainous pomposity of Oxbridge’s best.

It’s the ultimate lesson for aspiring British politicians. Fresh faced, with ambition and desire to make a difference they are confronted with the custom and practice of centuries. A bureaucratic minefield that tops anything Brussels can produce.

At first, it’s easy to see Jim Hacker as naive to the point of merely being indulged by the civil service. He learns fast, as a good parliamentarian should always do. Fun being seeing him turn the tables on the Whitehall establishment. Often at the expense of hysterically awkward moments and sporadic cynical manoeuvrings.

Last night, I watched “The greasy pole”[2]. Without a doubt this episode remains 100% relevant. It first went out in 1981. The story’s themes are universal.

A proposed industrial development offers secure jobs and potential prosperity. It comes with a hitch. Activism and noisy protests aimed against the project. Industry and the civil service want the factory to get built. The Right Honourable James Hacker sits on the fence. Blows hot and cold but realises that his political career pivots around sinking the project. The Minister wins out in the end much to the discomfort of the department officials.

It would be easy to write the entire plot in terms of 2025’s political difficulties. This morning’s News ran a story that wasn’t so far off the plot of “The greasy pole.”

A new Labour government minister tells of publishing a report that favours a point of view he wishes to get across. He continually mentions the name of the author of the report. Mimicking Jim Hacker as he makes sure everyone knows the report’s author, just in case he’s made a mistake.

Although, with the complete ridiculousness of the past British Conservative governments it may have been said that satire is dead. No, it certainly isn’t. Here it was playing out on the BBC on my kitchen radio at breakfast time.

This is the stubborn reality. In Britain we have a new absurdly named political party called “Reform.” They are flying high in the opinion polls because some people think the word has a political meaning. However, if these would be politicians were to gain a position of power, would they conduct long-needed reforms? Well, given the competence of the people involved and given the historic clashes between elected officials and civil servants the answer is most certainly – no.

It seems to me that new Labour government ministers are slowly getting the hang of the job. One year in they are still a bit wet behind the ears. Gradually, they are climbing the greasy pole. At any moment, because of the nature of the job, down they can come, and they know it.

The Intriguing Life of Jackdaws

As the grass turns brown, the sun beats down. Me, I just a lawnmower[1]. Now, that’s probably the daftest lyric that has ever been written in the history of rock. As I look out of the window at the parched grass there’s no way I’d take my lawnmower to it. If I did there would be nothing, but dirt left in its wake. Stubborn deep-rooted weeds and dead moss.

It’s summer. It’s unusually dry. Although, as the sun came up this morning, looking out of the bedroom window, a thin mist covered the ground. That was early. Between 4am and 5am. A thin white mist, low to the ground, must refresh the grass just a little. Most of nature sleeps.

As the morning progresses its not long before one dominant sound fills the air. It’s not the cars on the nearby road. One species of bird has adopted the tall trees, field next door and my garden. They are not a quite bird. To those that know their call is instantly recognisable. Their sound isn’t musical like some birds. It’s an incessant chatter. Loud and repetitious.

Jackdaws are having no trouble despite the dying grass and rock-hard ground. Our community of noisy birds is thriving. I guess their advantage is that they eat just about anything that’s going. Not much concern about predators as they take no care to hide their presence. I’ve seen them happily mocking larger birds. Showing off seems to make them happy.

As far as evolution goes, they have a lot of advantages. Equally agile hopping around on the ground as they are swooping and diving from tall trees. There’s no doubt they have a complex social etiquette. One or two minutes watching how they interact gives this away. Bigger, more mature, birds intimidate the younger ones.

Can’t say I like them much. More that I admire them for being so savvy. Jackdaws look as if they own the place. It’s not my garden. They are saying, we come a go as we please, you can share the space if you like. Sooty black masters of the airspace.

We’ll tolerate each other mainly because we have no other choice. Trying to scare a jackdaw is a fruitless task. They learn quickly. Soon sussing out that they can get the better of you.

As the sun beats down, I lay on my lounger. Listening to the endless chatter. Me, I’m just a bird feeder. Watching as the skies fill with shiny black dots. There for moment and gone the next.

Strolling

Mr fox strolled intently across the green field. Apologies, if in fact it’s a Mrs fox that I saw in the early morning light. His was a deliberate, nonchalant stroll. Knowing that tuffs of high grass and reeds provided cover. A stop, quick look around, and then onward. No reason to hurry.

From my window, this was not the first time I’ve seen a fox on his first light stroll. In the bright morning sunlight, there was a sheen coming off his coat. This was clearly a healthy fox. Agile, slender and strong. Unlike shy, less fit town foxes that I’ve seen wandering gardens. No scavenging from waste bins for this smart fellow.

It crossed my mind that prey must be plentiful at this time of year. Later in the day a pack of geese graze this unkempt wet land. Mixing with the Dexters. I’ve seen goslings waddling along behind their parents. Now, I suspect there are fewer of them to waddle.  

Sustainable Aviation: Innovations and Challenges

Gas guzzling continues to be one of aviation’s problems. Combustion remains that the heart of most aircraft power plants. Taking large amounts of fossil fuel. Squeezing energy out of every drop of gasoline. Gobbling up more day after day. Pushing out emissions.

As I look out across the garden, I see gliding effortlessly as the warm air rises, a Red Kite[1] gracefully circling. Wings outstretched they hardly move them as they climb. They’re a distinctive small bird of prey, easily spotted because of their forked tail. Now, that’s what I call efficient flying. Using all that nature provides and wasting little energy.

Human attempts at flying are a million miles behind these magnificent birds. There’s still so much to learn about aerial navigation. It’s a matter of control. The sensing of ambient conditions and the precision movements needed to ascend and dive at will.

The search is on for effective change. There’s no pretence that the way commercial aviation operates is unsustainable. It’s true that the gas guzzlers of the air guzzle less gas now than they ever have but the physical facts remain.

None of this is new. I’m about to send a book called “Towards Sustainable Aviation” to a charity shop. It’s not that there’s anything wrong with it. The book is full of pertinent analysis and observations. Trouble is that it’s dated 2003.

I’m led to ask – what’s changed in over 20-years? In answering my own question – quite a lot but not enough. Discourse has moved on from academic quarters to the political sphere. Aircraft have become more fuel efficient. Driven by economic imperatives as much as any concern for the climate. Research initiatives are generously funded to come up with answers. Solutions like hydrogen, electric propulsion, and SAF (sustainable aviation fuel) are slowly moving from theory to practice. A few prototypes are flying. Limited supplies of SAF are flowing.

Unmistakable that’s where the problem lies. For all the hype, policy and government funding the pathway to genuinely sustainable aviation disappears way off into the horizon. There are setbacks too. Gas guzzling is back in fashion. Certainly, in Trump’s America.

We could make a much more of the technology that’s currently available. Yes, there are costs involved. Change is not a free ride. That said, sticking with the status-quo isn’t free either. Legacy costs mount up. One reason why older jets disappeared from fleets so quickly.

The next generation of commercial aircraft must make major steps forward. Since the life of a typical aircraft type can easily extend to 30-years, then change must happen in design now.

Typically, commercial aviation moves with graduated change. There’s an inherent conservatism in the system, as might be expected when safety and security are paramount. Facing this global challenge, there’s a need for a degree more radicalism.

Since high impact disruption is also in fashion, it’s time for airlines and manufacturers to adopt a pioneering spirt. It’s been done before. In the 1960s, that pioneering spirt gave us the Boeing 747, the Jumbo jet. That opened flying to a whole generation.

Exploring a Riverside

Riverside walks can be pleasant ways of spending a sunny spring evening. That’s what I did on Friday. Sun shining with a cool breeze sweeping through the trees. Underfoot even the unmade-up paths were dry, which is testament to the rainless weather of recent weeks. Even so, the riverbank showed signs of the flooding of the winter.

Reading is a town[1]. It’s England’s largest town. Now, I didn’t know that until I looked it up. The largest English town that I’ve been familiar with over the years is Crawley in Sussex. I think of that as a large town but it’s less than half the size of Reading. It’s the railway that makes Reading. Reading railway station was the last stop on the Great Western Railway (GWR)[2] when it was first opened in 1840. After that the railway forged west to be what we know now as the main thoroughfare across southern England.

Reading town has a long history. That’s no surprise given its position on the river Thames. It’s where the river Kennet, the canal and the river Thames meet. An obvious place for trading since Roman times. It’s a commercial town. Glass sided office blocks and Victorian brick work. For all that it doesn’t stand out as an architectural masterpiece.

Another surprise for me was leaning that town twinning is alive and well. That Reading in twined with Düsseldorf in Germany. A city more than twice the size of Reading. In fact, until this last year, I’ve been more familiar with Düsseldorf.

Our walk ended at The Fishermans Cottage[3]. I’m happy to recommend this small riverside pub.

From there, on the walk back to the railway station I did see the one of the more notable sites in Reading. That’s the Banksy’s Great Escape artwork[4] on Reading prison wall. Oscar Wilde spent time in that jail. The artwork has got a Perspex cover to keep the pigeons off. And anyone else who might think of spraying it.

That reminds me. It’s not unusual to have a phobia about dogs. Although dog owners mostly have a difficulty in getting their heads around the fact. On my riverside walk dogs were not the problem. Amongst our small group of walkers had a different phobia.

As we got to the confluence of the Thames and the Kennet, we discovered the phobia of one of our walkers. Alfred Hitchcock would approve. The Kennet’s tow path attracts Swans. These Swans are attracted by people with food. With no inclination to get out of the gently flowing river these lazy Swans wait for passers-by to pay attention to their needs. That’s no problem.

It’s called Ornithophobia. A fear of birds. Birds flock when free food is on offer. The worst of these can be thought of as flying rats. I talk of pigeons. That how I think of pigeons. Tom Lehrer[5] had the right idea about these annoying birdies. Frightening them away, at least for a moment, cleared our pathway. Like a flash they returned as we strolled into the pub.

Travel’s Societal Impact

Privilege is all around us. It’s, by definition, not equality. It’s a privilege to live in a country not torn by war or where the environment has not been decimated. It’s a privilege to be able to protest and strongly disagree with the powers that be. Indeed, in this country it’s a right too.

Debates about the moral or ethical grounds of inequality will never cease. That’s a hope of mine. For the minute we become timid and cowed by an authority that would rather supress such debates, then that’s the end of our democracy. We’d be free no more.

A large part of my career has been in the aviation industry, in one way or another. Putting aside the military uses of aviation, that’s another debate, civil aviation and the travel industry are two peas in a pod. Flying facilitates travel. Largely international travel. Apologies to the cargo industry, leisure flying and so many others.

One phenomenon that is not new, is that of raising the issue of responsibility. For example, the consequences of tourism to natural environments are often negative. Not always so. Huge effort is made by some countries and organisations to make tourism a positive. However, generally there are significant challenges to be grappled with in making travel affordable for all.

Wealthy young Europeans have been roving across boarders as part of a rite of passage since the 1600s. A “Grand Tour” was a form of discovery, education and cultural enrichment. Today, a student might call that a gap-year. Time taken out of formal studies to travel abroad. The aim, as well as having fun, is to return a more rounded person ready for whatever life might throw up.

Where do we sit as a society in terms of the balance between personal freedom and our collective responsibilities? Are activists right to attempt to slam or shame travellers for the negative impacts that they can trigger? These are uncomfortable questions. Ironically, these difficult questions are often raised by the people who have enjoyed the privilege of travel.

In my mind, a debate on this subject of balance reflects greater societal issues. When we look at a basic hierarchy of human needs then international leisure travel may not be top priority. However, life would be less rich and colourful without it. Embarking on an epic journey, that takes a traveller outside their comfort zone, can be a life changing event.

To defend the freedom to travel, I cannot avoid looking at the other side of the equation. There is an overwhelming responsibility to do something restorative. Ignoring the impact of travel, particularly civil aviation, is not an option anymore.

I know there are some politicians who scream for the abandonment of Net Zero policies and all they entail, but they are extremely foolish. Shifting the burden onto future generations is reckless. Appealing to those who want to escape the debate, or force a return to mythical age, is nothing more than doomed short-termism.

This is one reason I’m an advocate for electrification and the exportation of radical solutions, like hydrogen powered civil aviation. Technological solutions are part of the path to take. That, in of itself, may not be enough but at least engineering change is permanent.

Solutions by design are far more powerful than ephemeral political posturing. Legislation can be overturned in a weekend. A whole new way of operating aviation can be sustained for decades.

The Revolutionary Role of Hydrogen

Hydrogen has a history with aviation. What could be better. A gas that is so light. So easily produced and with no need heat it up. With a lightweight gas-tight bag and a fair amount of rope, balloon construction took-off. Literally. The proof that hydrogen gas could lift a balloon goes back to the 1780s in France.

Sadly, the downside of this gaseous element is its propensity to combine with other elements. In fact, where would we be without liquid water. On this planet, that most basic and prolific combination of hydrogen and oxygen. Not so much sadly but more luckily.

Step forward about 250 years and we have a different vision for hydrogen in aviation. If it’s combined with the oxygen in the air that we breath, we get nothing more noxious than water. Since, the other forms of combustion, that populate our everyday lives, is distinctly noxious, surely hydrogen has a lot to offer. Talk about downsides. Burning fossil fuels is distinctly unsustainable. Polluting the atmosphere.

This week, I was looking out to sea. At the English Channel (No name changes there, I see). Standing on the pebble beach at Budleigh Salterton. They ought to have an award just for that name. It’s a small seaside town in Devon. The towns cliffs are part of a World Heritage Site, namely The Jurassic Coast[1]. 

Forget the 250 years of humans flying, cited above. About 185 million years of the Earth’s history is for all to see on the Devon and Dorset coast. When we say “fossil fuels” what we mean is that we are living off the back of Earth’s history. Society powers modern life on dinosaur juice. Well, not exactly but plant and animal life from hundreds of millions of years ago. How crazy is that?

Hydrogen, on the other hand, is one of the most abundant elements. It’s everywhere.

Modern day dinosaurs (politicians and pundits) insist that we continue to exploit dinosaur juice until it’s all gone. That’s putting aside any concerns about returning all that carbon to the Earth’s atmosphere. Carbon accumulated over millions of years.

Hydrogen can be a clean fuel. The problem is that saying that and then doing it are two different things. There are complexities that come with using Hydrogen as a fuel. It might be reasonably easy to produce, in multiple different ways, but it’s not so easy to transport.

Producing leak proof systems for transport and storage requires innovative thinking. We can’t just treat it with the familiarity of conventional fuels. Whole new regimes are going to be needed to get Hydrogen from where it’s produced to where it’s needed.

Producing leak proof systems for aircraft is a challenge. Given the odourless and invisible nature of this light gas, accurate and extensive detection systems are going to be needed. If the gas is to be consumed by fuel cells to produce electricity, then there’s going to be a constant struggle against complexity and significant expenditures.

What is reassuring is that none of the above is insolvable. At this time in history, we have the materials technology and control systems that make Hydrogen a viable clean fuel.

The Evolution of Air Traffic Control

Until civil air traffic started to grow the need for its control wasn’t the number one consideration. The pilot was the master of the skies. A basic “see and avoid” approach was taken. See another aircraft and avoid it at all costs. Note, I am talking about the early 1920s.

If you want a nice exploration of how it all started keep an eye on the site of the Croydon Airport Visitor Centre[1]. The first London airport was not Heathrow or Gatwick. No, there’s a stretch of grass, a hotel, industrial units and out of town shopping standing on the site in Croydon of the first London airport. 

Firstly, we can thank Marconi for the first radiotelephony. Providing a means for pilots to speak to airports enabled the development of Air Traffic Control (ATC)[2]. It got going out of necessity because there was limited space on the ground and many aircraft wanted to take-off and land.

Aerial navigation took off in the 1920s. A hundred years ago. WWII drove advancement in every aspect of technology. After WWII, the basic having been established, an international body was established to set standards for international flying. That’s where today’s ICAO originated.

Radar and VHF radio transmissions were the cutting-edge technology that enabled air traffic to grow. Radio navigation aids developed as did automatic landing systems. So, by the time the jet-age started there was a whole selection of technology available to manage air traffic. Not only that but the standards required for these systems to interoperate around the globe were put down on paper.

That legacy has served aviation remarkably well. Incremental changes have been made as new capabilities have been developed. Most notable of that evolution is to return elements of control to the cockpit. A traffic alert and collision avoidance system (TCAS) does just that. It provides a safety net.

What we have available to manage dense airspace and busy airports is a complex, highly interconnected, interdependent set of systems of systems and procedures that is not easy to unravel. Each part, in each phase of flight, plays its role in assuring safe operations.

News and rumours are that quick fixes are being demanded in the US. Responding to recent accidents and a perception that all the above in antiquated, a well know tech guru has been thrown at the “problem”. I shouldn’t be a cynic, as having a fresh pair of eyes looking at the next steps in the development of air traffic management should be good – shouldn’t it?

It’s my observation, as an engineer who knows a thing or two about these things, is that any simple solution means that the parties have not thought long enough about the problem. In this case there are no quick fixes. However, there’s likely to be incremental improvements and they will not come cheap.
