Collecting First Editions

Somewhere in several cardboard boxes I have books. Now, I know not where they are. Most of these books were published by Hodder and Stoughton. There were numerous print runs. Popular fiction.

What attracted me to these books was a character played by Roger Moore. No, I’m not talking about James Bond. Moore is probably best known for his portrayal of Bond. This was before he got that cinema role and global fame.

Author Leslie Charteris created a character called The Saint. That is Simon Templar. Roger Moore, as The Saint ran as a British TV series in the 1960s. What ran was an honest crime mystery series, with a Robin Hood style hero, who always won the day. His nemesis was a police inspector, even if they did cooperate towards righteous ends. The Saint didn’t always play by the rules. He fought tooth and nail to topple the ungodly.

Collectables are first editions of Leslie Charteris books. At one time they would appear forgotten in High Street charity shops. That day has gone.

The Saint Plays With Fire is worth revisiting. It’s a warning – especially now.

Avoiding Contrails and Enhancing Operations

Here I’m expanding on my earlier words on aircraft Contrails.

Airspace is a busy place. It’s most busy over Europe and the US. Over the oceans there’s more room, although on certain routes, like the North Atlantic, there’s plenty of daily air traffic.

Those who manage the airspace are primarily concerned with ensuring that aircraft collisions do not occur. The impact of mid-air collisions is devastating. There’re few people in aviation who can forget the events of an evening in July 2002. Over Überlingen, Germany[1], 71 people lost their lives at a time when the sky was not busy at all.

Managing the use of airspace is more than collision avoidance. Flying is perpetually concerned with the weather. What’s it doing, how is it changing and is it a hazard? It’s not just the safety of flying that demands up-to-date meteorological information. Knowing about the winds can enable more efficient operations, and that’s less fuel use for a given route.

Large thunderstorms need to be avoided. Regions of the world (example: intertropical convergence zone) make this a dynamic challenge. Manoeuvres may be planned but flight crews must be ready to act based on the information they have, like weather radar.

Turbulence is another phenomenon to be avoided, if possible. This can occur in clear air. It can be difficult to detect. Which explains the unpleasant examples that hit the News now and then[2].

Back in 2010, aviation had a reminder that avoidance encompassed any hazardous airspace. That was when an unpronounceable volcano in Iceland was spewing out ash at high altitudes. Plumes of volcanic ash, if ingested into aircraft engines, can cause major difficulties.

I’ve written these words to emphasise that the avoidance of contrail formation cannot be done as a stand-along consideration. It becomes one factor in a whole mix of factors.

Avoidance of contrail formation is about considering the mechanism that cause them to form. Clearly, the warmer the air is the harder it is for a contrail to form. The more humidity there is in the air, the easier it is for a contrail to form. Outside Air Temperature (OAT) and atmospheric humidity vary at each altitude. That relationship interacts with the aircraft inflight, and the outcome may be different for each aircraft type.

At least one academic study[3] says that adjustments of aircraft altitude of around 2000 ft could have a useful effect on contrail formation. That’s good to know but let’s not forget that Reduced Vertical Separation Minima (RVSM) [4] means a vertical spacing of 1000 ft in busy airspace.

My take on this fascinating subject is that there both a tactical and operational approach that can be practically taken by aviation.

At the tactical level, airlines can factor contrail avoidance into flight planning. Creating an algorithm that will weigh all the relevant flight factors. Improved sources of accurate and timely meteorological data and predictions will be needed.

At the operational level, it’s down to the flight crews to take advantage of environmental conditions as the opportunity arises. Much as dealing with turbulence, that is when safety and operational rules permit. To change altitude when its beneficial, computational help is likely to be needed. Over the ocean, air-ground communications systems may need to be further improved. An altitude change that avoids contrail formation but increases fuel consumption would not be a sustainable solution.

These computational tasks may well be well suited to machine learning. A useful application of artificial intelligence. I can imagine a cockpit weather radar display with a new set of symbology that indicates a low probability contrail formation zone ahead.

[Back in the 1990s, I worked on RVSM when the ARINC organisation was creating international standards. Safely increasing traffic in the North Atlantic region. Additionally, I participated in the certification of Future Air Navigation System (FANS) 1/A for use over the ocean. FANS led to more efficient aircraft operation due to shorter flying times and decreased fuel burn.]

Revisiting Brexit: Lessons

In life partnership is key. Most of us have no desire to live as a hermit. The dull confines of a hermitage are best left to a small few. That extends to communities as well. It’s rare for societies to live in isolation and avoiding relationships with others. People come together when they share values. So, it has been in Europe in the post-war era.

Relative to the astronomical losses that the whole UK accumulated because of Brexit, the gains of the latest European Union (EU) – UK deal are modest. The positive take, from Monday, is the direction of travel. Cool heads have prevailed, and a new deal of mutual benefit to both parties has been agreed. There’s more detail to follow as might be expected.

Unsurprisingly, those who failed miserably over the last decade are now carping bitterly[1]. Remember Johnson, who as UK Prime Minister (PM) had a large parliamentary majority that he threw away. His incompetent administration sealed an extremely bad deal.

The years following the 2016 referendum have been wasted years. Tedious nonsense about Brexit benefits have echoed through those years without anything good arising. Brexit “freedoms” are a metaphor for acting foolishly and without any relation to prevailing facts.

Last July, the British electorate said “no” to the parade of Conservative Party catastrophes[2]. The UK decided to go in a different direction. It was the Labour Party that toped the poll. Lib Dems and Greens doing well too. Since the General Election, and since the beginning of the year, the ebb and flow of global events has been truly turbulent. In historic terms, when UK PM Harold Macmillan was asked what the biggest challenge for a statesperson was, he replied: “Events, dear boy, events”[3]. Seems he was right.

Starmer is a fascinating character. Not the characteristic statement of a lifelong liberal, like me. The tool makers son, who schooled in Reigate, to become a top lawyer, climbed the slippery pole of pollical life, to become PM. Along the way he’s done what’s most typical of successful British politicians. That is, he’s changed his mind and allegiances along the way. Going from Labour Party leader to PM in 4-years is quite an achievement.

I don’t have to agree with the PM. In fact, as far as his priorities in government, I don’t agree with the PM a lot. Although, I’ve personalised these words, I wish to take due care. I speak only of him as PM. I’ve never met him. So, let’s focus on his role.

An EU-UK Brexit “reset” was inevitable. If it didn’t happen now, it would have happened eventually. Why would both global trading partners persist with a lose-lose situation? Dealing with serious national issues is a PM’s job. It’s not to avoid or obfuscate. Here Starmer is praiseworthy. Instead of struggling on as if nothing could be done, he’s acted.

What I dislike is the mindless bile that emerges in the conservative Press and in dark corners of social media. Swilling around with ever more hostile adjectives, it’s as if all sense has been lost by part of society. By all means express unhappiness if the cherished beliefs of Brexit are being contested. Everyone has a right to criticise. Please do it in a civilised manner.

What’s foolish is the leader of the Conservative Party who has jumped on the pessimist’s bandwagon. Why do they persist in talking Britain down? Gloomy and unattractive it’s no wonder their poll ratings are plunging. Instead of speaking on Europe, with eloquent and knowledgeable thoughtfulness, we get a diatribe of prejudice and backward thinking. Sad indeed.

Understanding Contrails

Crisscrossing the sky, as I look up on a clear day, there are civil aircraft going about their business. People travelling across the Atlantic or coming back or on a day trip to Glasgow.

These shiny pinpoints of light in motion, set against a blue sky, are all the more visible because of the vapour trails they leave behind. Aircraft speed through the rarified atmosphere to leave a momentary trail as evidence of their presence.

Up with the aircraft in flight are natural clouds. Up at 30,000 feet there can be Cirrus clouds[1]. There might not be much air pressure at that altitude but there’s enough moisture to support cloud formation. The word “wispy” sums them up.

Aircraft create condensation trails that are known as contrails. How the English language likes to shorten. They are not mysterious or generate with evil intent in mind. It’s simple physics.

In my bathroom, with hot water gushing from the shower, moisture is the air. When that moist air meets a cold surface, like a window, condensation is sure to be seen. Airbourne it’s not so different. Hot emissions from powerful jet engines shooting out into a cold low-pressure environment and guess what?

Typically, contrails don’t last long. If there’s appreciable wind at high altitude, then they get dispersed quickly. Not only that but the icy temperatures up there soon return things to the status-quo. There are days, when the air is still, that the sky can become a crisscross of contrails where dispersion is more like a gentle merging.

The theory goes that the cumulative impact of lots of high-altitude flying is like the impact of additional cloud formation. It’s water vapour after all. It’s known, high altitude clouds can contribute to the greenhouse effect.

The point I’m getting to here is that lots of flying contributes to climate change. Primarily because of the burning of significant amounts of fossil fuel. As a secondary consideration there’s the issue of contrails across the globe.

This leads to the question – can their formation be avoided? Even, is there something useful to be gained in doing so. Trials and research are trying to establish the answer to these questions[2].

Initially, contrail avoidance sounds like it should be relatively easy to do. However, like so many good proposals it’s not so easy. Change needs to involve air traffic management, flight operations and international regulators.

First the atmospheric conditions need to be detected or predicted in a given location and then an avoidance needs to be planned and undertaken in coordination with everyone flying at high altitude at a given time. Lost of data to crunch.

It’s possible, in oceanic airspace, a dynamic aircraft system could perform this avoidance function. It would be an interesting design challenge for an avionics company to take up.

Relationship with the EU

Monday, Monday[1]. It’s a wonderful 60s song. Harmonies and mood are perfect. I wonder if the harmonies and mood will be perfect for the Prime Minister (PM) on Monday. Already the Sunday Press are setting the stage for Monday’s performance.

Reset, recalibration, reheat, rekindle, re-whatever. It’s a moment when relations between the UK and the European Union (EU) can make realistic progress[2]. In world full of uncertainty (could be a song in that one), for once the direction of travel is a constructive and positive.

I think the word “deal” is getting overplayed. Indications are that there’s no fundamental shift from Brexit meaning Brexit, as one former PM liked to say. In fact, the current PM is being highly cautious in the light of his Party’s reading of the latest opinion polls. For no sane reason I can think of, the swivel-eyed loons of the far-right are making hay.

It’s astonishing me how dim-witted the Conservative Party is in objecting to something when they don’t even know, for sure, what it is. Mind-blowing. And the rum cult of Reform Party doing the same with extra bile. What a load of prehistoric fruit loops.

Brexit supporters are spreading misinformation, again. Saying that UK has no influence. It’s true, the UK doesn’t have votes in the European Council or Parliament, but significant influence can be exercised on standards, and regulatory guidance, nevertheless. A better “deal” can bring much greater influence. Absolutely vital in the digital world, and for the UK, a country with a services-based economy.

Brexit has cost the UK dearly. The UK Treasury would have billions more in its coffers if the 2016 referendum had never taken place. The standard of living of every person in the UK is lower because of Brexit bungling. Ideally, that great mistake is an event to be written up for the history books and then forgotten.

On top of the above, uncharacteristic moves in the US, with Trump tariffs there’s nasty hit at the UK’s future prosperity. There couldn’t be a better time to repair relationships with the UK’s nearest neighbours. The countries with which we share most of our long history.

Even for those on the political right, practically, the EU is never going away, so until the day the UK rejoins the block, it’s wise to have the best possible relationship in all matters. Goods, services and people need to connect as a case of mutual benefit.

It’s time for hope. An optimistic tone should be set. A smile. Let’s hope we are singing Monday, Monday so good to me, Monday morning was all I hoped it would be. Naturally, that there be no crying, come Monday evening.

Work-Life Balance

Now retired, I sure didn’t always do this daily balancing act well. It was a difficult one to master at the best of times. Especially when work involves travel and was dictated by unpredictable events and demands. In aviation, I mean experiences like accidents and incidents, and the more unusual, like the closure of airspace by the volcanic eruptions in Iceland in 2010.

The maxim: “If you love what you do, you’ll never work a day in your life” can be a deceptive little ditty. That’s because time travels incredibly fast when busy and working at interesting problems.

What advice would I give to my younger self? Learn to say “no” in a smart way. Don’t let pride or guilt, those testy emotions, influence too much. And don’t let others use them against you.

Additionally, jobs with responsibility do have unpleasant and mundane aspects. Say, someone’s performance appraisal didn’t go well, or the budgetary forecast were way off or the advice you gave was based on flawed assumptions. These situations happen to everyone. The message is don’t take this baggage home if you can avoid it.

Eurovision 2025: Highlights and Predictions

Joyous entertainment. An ever-flashier lighted spectacle. Comic, dramatic, eccentric. It’s all of these and more besides. That’s Eurovision.

This year’s crop has variety. There’s peculiar voices that make me cringe. There’s pop with extra added pop. There’s retro seriousness with genuine heart. There’s dressy comic fun. There’s the music equivalent to adrenalin filled energy drinks. There’s sexy costumed excess.

Thank God for public service broadcasting. Hats-off to the European Broadcasting Union (EBU)[1]. Every year they come up with a bright spot in a troubled world. The biggest music show in the world. This year, Switzerland is doing a banging job.

The Grand Final of the 69th Eurovision Song Contest, takes place in Basel on Saturday evening. Worldwide people will be glued to their screens. Here’s an event that bring the world together. Yes, a smidgen of politics creeps into the arena. Thankfully it’s not the dominant force. Clearly, the theme here is unity through music. Celebrating what we have in common.

Sweeden (KAJ – Bara Bada Bastuare) are highly rated for a win. Personally, although I like these jokers and their act, it reminds me too much of a Monty Python sketch. He seems to be popular with the audience but I’m not a fan of Tommy Cash. Estonia is going to do well. For me, Espresso Macchiato is just too blatantly silly.

Granted it’s not the most spectacular single act, I like Armenia. The man is full of raw energy. PARG should be high on the evening’s final list. There’s something devilish about Miriana Conte of Malta. Colourful in excess. She should get a lot of votes for her well executed exuberant spectacle. Looking away is impossible.

I maybe a mild-mannered prude but please let’s not have Finland and Erika Vikman win the night. The act is too contrived to be edgy and get noticed. And sorry Mr JJ. Wasted Love is more like wasted painful screeching in my book. Austria nil points.

In a more traditional style, Klavdia from Greece has a simple honesty that shines through. That should be rewarded with votes. What The Hell Just Happened? Could be applied to the Saturday night result when the time comes. It’s the title of the United Kingdom entry. I wish the group Remember Monday good luck.

Eurovision is going from strength to strength. This inheritance is to be treasured.

POST: In my mind an unexpected result. Regardless of the political element of large-scale public voting, I didn’t think the Austrian entry had much going for it. Same with Israel. 2025 has been a bumper year for choice, in terms of the variety of acts, but the winners are run of the mill. Good luck to Austria in hosting the competition next year. I’m sure they will do a fine job.

Action Shapes Outcomes

There’s a foolishness that comes with great power. It gets played out every day over the News media. It’s when notable person x or y says words to the effect; nothing will happen unless I do it. This common notion gets projected to us through mass reporting and commentary.

Every second is a pivotal moment. A last chance to move, or a last chance to act. As if time stops when we know it branches into countless possibilities. Fine, pivotal life or death moments do exist. It’s only that they are less numerous than we might be led to think. Drama takes its place in the theatre of the everyday[1].

There’s an ancient lesson to learn. It goes like this, in a simple demonstration. Place any finger into a glass of clear water. Now, remove the finger and observer the hole.

It’s a lesson Archimedes would appreciate. Although he’s famous for displacement being an indicator of what’s doing the displacement. Between the two it’s the water that’s the constant. The ebbing and flowing of time. At least as we humans perceive it.

It’s not that an individual can’t make a difference. Far from it. Individual action can make a dramatic difference. Doing the right thing at the right time, if the opportunity arises, can be the difference between catastrophe and nothing much in particular, as an outcome. In the world of major accidents, designers and operators desperately try to avoid the possibility that a single act or failure that leads to catastrophe, but it does, on rare occasions happen.

The point in discussion is the matter of what is indispensable. How often do we get to choose what is indispensable? After an event, it’s easier to answer the question. Looking back, it can be said that the factor that made the most difference was this one or that one. Before an event, we are in the land of probabilities and shiny crystal balls. Mathematics and mysticism.

The Cuban Missile Crisis[2] offers a lesson. It was only in retrospect that people learned of the action of a Soviet Naval officer who prevented a submarine from launching a nuclear torpedo.

History tells how the pivotal moment arrived. That said, there was no way the man concerned knew before time that his role would be indispensable. History would be written dramatically differently if a nuclear engagement had happened.

In the end it comes down to doing the right thing at the right time when the opportunity arose. Sometime swimming against the tide of events. Not magic exuded by a powerful individual strolling the stage.

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.

Myths vs. Reality

We live in a world of contradictions. What am I thanking about? The current febrile immigration debate has all the hallmarks of magical thinking. Here we are surrounded by water, living in an economically active favourable part of the world and yet public concern is directed at “others”.

I’ve no problem with the current British Government berating the past Government for not fixing a problem. It’s normal for a governing party in the first couple of years of their term of office to point the finger of blame. It’s easy. Painting a picture of past failure makes the road ahead clearer. It’s easier to start from a point of low expectations.

However, it seems it’s not the resurgence of the Conservative Party that the Labour Party are concerned about. Today, such a prospect would be like the reincarnation of a squirrel that had been run-over by a 42-ton truck driven by the electorate.

The announcement of the day is setting an ambition to squeeze immigration. Recent local elections have shown that this banner flies well with those who vote in local elections. Because the opinion polls give bizarre indications too, the questionable assumption is that if a General Election was called by an irrational Prime Minister there’d be a surge in far right-wing voting.

We have new kids on the block. They are not at all new even if the have a new name. It’s an Orwellian name. Because an ultra-conservative party isn’t in the business of newness as much as they are stirring up ancient antagonism.

Anyway, the Reform Party are the current snake oil salesman selling their easy solutions to difficult problems. They were once named; Referendum, UKIP and Brexit Party. All proponents of magical thinking and with a poor track record.

The story goes like this. Stop overseas immigration and make the hordes of economically inactive people of Britan take-up the vacancies that would result. When Reform voters hear this narrative, they don’t think it applies to them. They believe there’s a mythical group of lazy people who need to be forced back to work and off overly generous State benefits.

In this public debate it’s as well to look at the numbers[1]. Reform voters are predominantly of 50-years and older and the economically inactive are predominantly 50-years and over[2]. Thus, I say, we live in a world of contradictions.

COVID did see a large number of people take, or be forced into early retirement. Those who have experienced a lifetime of their terms and conditions of employment being degraded took the opportunity to do something else. Often that included voluntary work or caring roles. Reform have concocted plans to pressure people back into conventional employment. These plans are uncosted and not cheap. Lots of government funded incentives and training, for example. In the real world, funding must come from somewhere. That’s likely to be from the privatisation of health services and cancelled benefits. In this scenario don’t expect to get a state pension until well past 70 years
