Transport of Delight

Air Taxies are becoming a reality. It’s not Science Fiction anymore.

The history of the “hackney carriage” is along and illustrious one. They remain firmly attached to the road. They do move with the times. From horses to combustion engines to electrified cabs[1], I wonder if London back cabs will adopt Hydrogen fuel next?

Providing safe and reliable public transport for about 8-passengers, in reasonable comfort, with a limited amount of luggage, they are a vital part of the city landscape. Ferrying people from place to place and even going south of the river (a popular saying from the people who live north of the River Thames).

In New York, “Yellow schools of taxi fishes” in a song by Joni Mitchell. Schools or sholes of taxies swimming in a sea of traffic. Frantic and colourful as they are shown in a lot of 1970s movies. A chaotic scene where the protagonist runs out into the middle of dense, barely moving traffic.

What happens when these modern convinces take to the air? If they were still with us, I’m sure Flanders and Swann[2] would have written a song about this new marvel. The distain of London buses towards black cabs is there in the lyrics. So, as air taxies take-off, as it were, will the cab drivers of the city protest or join the ranks of new flyers?

Please don’t answer that question. I’ve in mind more serious issues. The whole history of aviation safety data analysis shows us an immutable fact. Take-offs and landings are riskier than flying in at altitude. It really matters not if flying horizontally or vertically.

How does this come to be? A simple answer would be to say that the results of aviation accidents eventually end-up on the ground. Gravity does its work. Put that aside for a moment. Take-offs are optional but landings are mandatory. That’s a traditional saying that amuses non-flyers but is all too real to pilots and alike.

The act of taking a flying machine from the freedom of movement in 4-dimensions to a preselected stationary point on the ground. Those policies and plans that are published refer to Vertiports being established much as Heliports have been in the past. Some may double up. The theory is good. A pre-defined clear space that can accommodate a typical eVTOL aircraft used as an Air Taxi, with all the necessary operational and safety provisions. Surrounding areas protected from the down wash of the Air Taxi. Care to remove any foreign objects from the vertiport surface. A mini terminal to add to the cityscape.

One of the biggest variables in this brave new world of public transport is as old as the hills. It’s the local weather. Dubai can roast an aircraft with clear skies and 50C while Aberdeen can soak them in rain and impenetrable mist. Dust and wind can blow through Marseilles while deep snow and ice covers Montreal. Whilst in Lahore the air itself can be hazardous.

Terrestrial vehicles do cope. Often this means that there are different rules and regulation that take account of the local conditions and priorities. The impatience that some advocates have for a rapidly formulated globally set of harmonised rules and regulations might be misplaced. In fact, it may even impede the introduction to service of Air Taxi services.

Since I’m discussing the urban environment, I can presume that any accidents and incidents will be the focus of a great deal of public attention. Ultimate safety is a nice aspiration, but then reality takes hold. There will be occurrences. When they happen, city councillors are going to have their say.

FLANDERS & SWANN – ‘A Transport of Delight’ – 1957.

Determinism in Aviation Safety

The arrow of time. We fly from past, to live in the present and anticipate the future. Sir Isaac Newton would be proud of us. By unravelling laws, that where always there, the means to anticipate the future was illuminated.

In civil aviation, we have devised and grown a whole regulatory system that depends on learning from the past, doing calculations today and flying with a belief that we know what’s going to happen next. Flying is predicated on a reasonable degree of predictability. There’s clear logic in this way of thinking. Just imagine powering up a couple of massive jet engines and starting a take-off roll without being extremely confident that at a certain speed the laws of physics will do their part and the ground is left behind.

We don’t establish a reasonable degree of predictability by looking at a crystal ball or taking up alchemy. Yes, we do still depend on reasoned expert opinion in addition to doing calculations. The minute those expert opinions start to shift away from grounded reasoning and careful deliberation then danger is afoot. This is one of the arguments for treading carefully when political opinions start to come to the fore. The laws of physics are not established by a public opinion poll. Nevertheless, it’s equally polarising to say that there’s no political dimension in the aviation regulatory system.

Anyway, that’s not the subject that was on my mind. Conversations about Artificial Intelligence (AI) are more prolific than those about self-help books. Even the shelves of popular high street bookstores are starting to fill up. The non-fiction titles with AI, either as the main subject or as an adjunct are numerous. It’s the fashion to write something literate or purely speculative.

I’ve mentioned the word “determinism” before. It can be interpreted philosophically or in a more scientific and technical manner. Determinism is a belief in the inevitability of causation. That chain of cause and effect that is so familiar to anyone reading an aviation accident report.

Understanding what causes something to happen in a moment in time goes back to my initial subject of a reasonable degree of predictability. In aircraft certification, no matter how complex the system, when presented with a system safety assessment we expect a comprehensive and reasoned set of statement. Predictions about the “what ifs”. What if an aircraft part fails and what happens next? What happens in combination with other failures?

This is where AI is potentially problematic. All the reasoned arguments in the world go out of the window if a system, subject to the same conditions, behaves one way on a Monday and differently on a Friday. Not to mention the weekend. I could say, AI is remarkably human in that respect.

The subject that was on my mind is not the inner working of complex aircraft systems. Certification experts are on that one. It’s possible to put boundaries around the behaviour of some aircraft systems. What’s more fascinating is the evolution of AI interactions with us mere mortals.

Let’s say I have the responsibility for return to service of a transport aircraft that has been subject to maintenance. A pile of documentation will provide the evidence that the work conducted has been correctly completed. It conforms. Amongst that paperwork might be an output from an AI driven diagnostic system that flashes a green light to say everything is fine.

Now, playing with the “what ifs”. What if it’s not fine given that the conditions experienced were way outside the AI systems training and it does a creative hallucination. The person signing the release to service documentation would have no idea or facility to question the green light. But it’s their signature that matters in the process of return to service.

There is a point of concern.

The Future of Driving

What next? There’s a growing number of Electric Vehicles (EV) on the market. In fact, the diversity of choice doesn’t make choice easy. Such a variety of different sizes and configurations. Cars big and small. Hybrids too. Every new generation offering more range and more bells and whistles (technology).

My car is getting near to its 11th birthday. It runs exceptionally well. Trouble is age, ware and tear, can’t be escaped. Bills start to ramp up as millage takes its toll even if it hasn’t done – yet. German engineering isn’t always what its cracked up to be except my car does fit the stereotype. Temptation is to buy another one.

My first trip to the US was back in the early 1980s. Four of us drove up and down the west coast. Seeing spectacular sights and meeting amazingly friendly people. American cars of that time were of the Cagney & Lacey generation. Meaty metal boxes that handled like a crate of jelly. Gas guzzling but, who cares, gas was cheep in comparison with European prices.

Wide empty roads, outside the cities, where the landscape filled every vista with new wonders. City driving wasn’t so pleasant. Freeways where the occasional Blues Brothers like police car buzzed past at speed. Air quality dropped a million percent (exaggeration). Jams in more lanes than we’d ever imagined possible.

So, are Electric Vehicles (EV) the spawn of the devil? I take the point that not everything is as rosy as the marketing departments of the manufacturers would have us believe. Some prestige models are bulky and heavy. These are not well suited to the narrow pothole heaven of England’s poorly maintained roads.

That said, the change is upon us, and it would seem foolish to go backwards. Once over the initial purchase price, which does seem to be coming down, EVs don’t cost much to run. There’s a simplicity of electric motors which a high-performance reciprocating engine can’t match. Not only that but high-performance reciprocating engines have probably reached the limits of what can be squeezed out of them. Decades of development in reducing tail pipe emissions.

It’s clear Electric Vehicles (EV) have a long way to run. Battery technology will continue to improve. That’s one to bet the house on. It’s because there are so many applications for high power density batteries. If you are aiming at a Nobel Prize in Chemistry, that’s the way to go.

Driving a car with no tail pipe emissions does have a holier than thou feel about it. If we want cities to be healthy places to live, then something must be done. I wouldn’t want to live near the world-famous Hanger Lane Gyratory[1]. Or anything like it. In England we built massive road systems on top of streets designed for the horse and carriage.

Looking at new cars, like the Mercedes-Benz CLA[2], I must admit I’m tempted. Putting that up against the lumbering thundering rust buckets of the 1980s and there’s no comparison whatsoever. Whether it’s sheer performance or climate change that motivate a purchase decision, the days of conventional petrol and diesel cars are numbered.

The Digital Dilemma: On Youth

Every modern technology challenges us all. Technologies’ relentless path is unstoppable. Technology inevitable is a two-edged sword (good and bad). Not everyone will accept these statements. This is my observation of the last 50-years in the UK.

1976 was an incredible year. It’s being celebrated as the year of Punk Rock. That’s just one snip out of the scrapbook. In fact, the music scene was over briming with diversity in that year. Low-cost microprocessors were coming on to the market. Forward thinking innovators, like Sir Clive Sinclair[1] were thinking about how to put these into the hands of everyday people. Trade Unions were signalling concern that this technological revolution would mean the loss of millions of white-collar jobs. Politicians ran around in fear of a severe threat to the established social order.

Let’s just say, there was no less a public clamour about how to react to the transformations that were coming down the road as there is here in 2026. What is a 16-year-old to make of all this at any time? I was 16 in 1976. Now, what’s it like to be 16 faced with current relentless and often troublesome pressure of social media?

That’s one phenomenon that I didn’t have to deal with as an energetic engineering apprentice with the thrust for speed and motorcycles. That said, all the stuff we hate about social media, bulling, harassment, intimidation, hurt, and suffering were still ever present in society.

My starting point is that banning things is to be avoided if there’s a better way. It’s profoundly illiberal to reach for the law to ban as the only approach to problem solving. My caveat. If there’s evidence of systematic harms being caused to a vulnerable population then a ban may be inevitable. In this I can cite the restrictions that are placed on young drivers and motorcyclists. Without legislation restricting activities our society cannot accept the resulting death toll.

Age limits are part of a civilised society. So, a dilemma exists. What level of harm triggers a ban? That is assuming that an enforceable ban is the most effective way of achieving reduced harm. In reality, a ban by law does not aways work. Either people find a way around it or it turns out to be unenforceable. It can also become smothered in processes and procedures to be rendered useless. Exceptions and qualifications.

How about banning mobile phones or social media for young people? That’s two quite different moves.

Mobile phones are part of the digital landscape. No one should go through future education without a necessary exposure and grounding in the digital world. It’s their world. It’s not going away. Social media is different, but it’s a nebulous product. It’s not so easy to sit down and write a useful and workable definition of what’s included in social media. Even if a law is written about social media, within a brief time it will turn into something different. It’s a combination of communications technologies.

What we do need is regulation to minimise harm done. That needs to be agile but comprehensive. A most perplexing task. Up until now, regulation is the digital realm has been ad-hoc and focused separately on application areas. Much more work is needed.

Evolution of

Looking at the weird and wonderful picture of an unlikely lump of materials with wires hanging off, it’s easy to dismiss. A laboratory experiment that drew together theory and practice to produce a brand-new electrical device. Not something that occurred in nature. Even though its behaviour is of that of materials in nature.

Certainly, the implications of this experiment could not have been fully understood at the time. That said, progress to industrialise this new device was rapid. By the time of 1956, the “inventors” were awarded a Nobel Prize in Physics. In 1947, the transistor, was a fruitful combination of science and practical thinking in a laboratory where that was encouraged.

Bell Laboratories, given its history was a logical place for arguably the most important modern invention to be first put together. Arguing over “most important” there are several matters to consider. For one, how universal, how ubiquitous would this humble device become? Would it have a dramatic impact of everyday life for decades after its invention? Would it change every aspect of human organisation? Would its design, development and production become essential to the world? The simple answer – yes.

My first encounter with the germanium transistor was as a boy in the 1970s. Stripping them out of junked radios and record player amplifiers. Building simple circuits. PNP germanium junction transistors were tiny tin cans with three colour coded leads. With a soldering iron and a primitive breadboard there were plenty of designs in popular magazines to copy. Now, this is considered as vintage technology since germanium has long given way to silicon.

The clock, the radio, the bathroom scales, my shaver, my toothbrush, even in my bathroom every appliance contains circuits that are transistor based. It would be possible to live without some of these items, or at least substitute them with the mechanical versions, but that’s only for eccentrics, museums and heritage houses.

In 1947, the prototype transistor was on a bench being studied. It came along too late to play a part in the huge leap forward technology made during World War II. What became apparent is that the technology that had been developed using thermionic valves was convertible into a transistor-based versions. Size shrank and performance improved dramatically.

What’s my message? It’s another way of looking at so called artificial intelligence. Technology doesn’t come out of the blue. It doesn’t plot new pathways in the first years of its invention. It often takes things we already do and speeds them up or makes them cheaper or makes them more lethal.

We create another stepping stone upon which further developments can take place. So, maybe there is a South Sea Bubble about to burst. Much of the frantic investment that has taken place assumes that artificial intelligence is of itself a wonder. Let’s say it isn’t. The wonder is what it will allow us to do. Much of that side of the coin is a massive unknown. Much as the three who invented the solid-state transistor could not have envisaged tens of millions of them stuffed inside every computer chip on the planet.

Vintage germanium components are sough after by specialists. Apparently, audio amplifiers sound better to those who are sensitive to certain musical tones. Artificial intelligence has a proliferation of applications. A lot are gimmicks. Some are extremely serious.

Civilization’s Edge

Civilizations rise and fall. That’s not new in the human experience of the last couple of thousand years. One of the causes of failure is an encounter with an entirely unexpected threat. When I say “unexpected” I mean unprepared for threat. Then finding that the defences that have been constructed fall simply and quickly because they didn’t anticipate that threat.

Another reason for failure is a perpetual human characteristic. Arrogance. Everyday imagining that the pinnacle of achievement is – now. Look how smart we are in the 21st Century. Capable, Superman like, of leaping so far ahead of our forefathers.

I’m a child of the analogue age. I was born into the space age. What that brought us, by necessity, was the digital computer in all its myriads of forms. Yet, from day one, it’s no better that a mass of fast switches. Ones and noughts. Nothing more. Nothing less.

With miniaturisation and an understanding of how materials work a massive, global, interconnected digital system, called the INTERNET, has been constructed. It’s flexibility and utility are undeniable. Its extended human capabilities way beyond that of past generations.

Now, I can start a sentence with “however” or “but” or despite this fact. The whole enterprise is still an unfathomable, dynamic number of ones and noughts.

There’s a kind of vulnerability that is elemental. Whatever might be written about powerful Artificial Intelligence (AI) systems it’s fair to say that the “A” is entirely accurate but the “I” is a bit of a myth. Mimicking intelligence is more the order of the day. That does make people shudder because that mimicking is so fast and draws on a massive amount of information. Seemingly that surpasses human capabilities. It doesn’t.

I write not of the machines that we have today but of those to come. I’ll resist the mention of the number 42. What’s happening is an acceleration of developments. These highly versatile tools that are permeating every aspect of life are not frozen in time. They overhaul themselves on a regular basis. What comes next is indeed machines that make machines. Algorithms that write algorithms.

Humanity is unprepared for the emergence of an intelligence that genuinely fits that bill. The whole idea of sovereignty and human autonomy might go out of the window. The ability to exercise control over where we are going is lost.

There are a lot of wealthy folks who are of a libertarian frame of mind who don’t seem too concerned about this race to the point of loss of control. This could be an expression of arrogance or ignorance or both. It could be the ultimate expression of short-termism.

It’s going to require real effort to hang on to democratic systems where we all have a stake in the direction of travel of our society. Money buys influence. Now, that influence is adverse to the idea of trying to regulate or moderate the advance of technology.

Civilizations rise and fall. Are we racing towards a cliff edge? Put aside climate change for a moment. Stop me from any tendance to doom-monger. My thought is that a comfortable, stable, prosperous society needs regulator instruments that work to mitigate threats. Let’s not be persuaded to ignore that reality.

Exploring Airworthiness Knowledge

How many good books are there on aircraft airworthiness? I don’t suppose a lot of people are going to ask that question. General introductions to airworthiness are not necessarily bedtime reading. This thought came to my mind, this week, because I had some time to kill in a library. A particularly technical library in London[1]. It’s at the Institute of Engineering and Technology (IET).

Sited in a grand building on the banks of the River Thames. Savoy Place, as the name suggests, is next door to the famous hotel of the same name. What marks it out is a large statue, not of some long-forgotten stage actor or army general, but that of Michael Faraday[2]. His contribution to the modern world is enduring and undeniable.

I’ve been a member of this august engineering institute since my student days in the early 1980s. Then it was known as the IEE. One “E” being for Electrical. Our lectures encouraged us students to join and once done so they have us for life. Members worldwide have access to their books, databases and standards.

I could draw a thread between Faraday’s work and 21st century aviation. It’s a mighty wide thread and one that’s growing all the time. There are so many aspects of electromagnetism embedded in aviation. For example, without electric motors and servos, we’d still be controlling aircraft with strings and wires. Fine, hydraulics play their part too.

Technology has moved on. It continues to move. Electrification is displacing hydromechanical systems. The age of electric propulsion is getting closer as developers experiment with a myriad of different configurations of motors for different new aircraft types. More and more electrical power is needed to make modern aircraft tick.

In the IET’s library there are a few books with the word “airworthiness” on the cover. It’s a distinct niche. More often technical references contain huge amounts of material that concern or impact airworthiness, but the word itself is reserved for the more discerning.

One I picked off the shelf was “Airworthiness: An Introduction to Aircraft Certification and Operations” by Filippo De Florio[3]”. For me it’s full of familiar material. I was surprised at the level of detail and range of coverage. In its latest version, it’s reasonably up-to-date too.

One book that was not on the IET’s shelf is “Initial Airworthiness: Determining the Acceptability of New Airborne Systems” by Professor Guy Gratton. I believe he’s updating this book now.

There was a copy of “Aircraft System Safety: Assessments for Initial Airworthiness Certification” by Duane Kritzinger. Again, for me it’s full of familiar material.

Another book that was not on the IET’s shelf is “Aircraft Continuing Airworthiness Management: A Practical Guide for Continuing Airworthiness Engineers” by Daniel Olufisan.

What I’m wondering now is how many other contemporary books are there on this subject. That is up-to-date references. Yes, I know I could do a quick search to turn up an easy answer but that tells me nothing of the quality of the publications. All four above are worth a read.

Help me out with some suggestions – please.

Trust in Voluntary Reporting

Hard data is immensely useful. Now there’s a surprise. That’s facts and figures. That’s accurate descriptions of occurrences. That’s measurements and readings of important factors. From this kind of data, a picture can be painted of events good and bad. However, this picture is not complete. It’s certainly not complete for any system that involves the interactions of humans and machines.

What’s often less visible is the need for what I might call – soft data. As such it’s not “soft”. I’m just using that loose term to distinguish it. Fine, you could say that social media is littered with the stuff. Vast qualities of instant judgements and colourful opinions. An array of off-the-shelf solutions to life’s ills. That’s all well and good for entertainment. It’s not so useful as a means of getting to the truth.

In civil aviation voluntary reporting systems have been around for several decades. They are not always successful, mainly because there’s a fair amount of trust required to use them when something major happens. When volunteering information there needs to be a level of assurance that the information will not be misused.

The human inclination to seek to blame is intrinsic. We wake-up in the morning, look out the window, and if it’s rainy and windy then someone is to blame. Probably a weather reporter for not warning us of a coming storm. Blame is a way of making sense of negative events without having to do lot of tedious investigation and analysis.

Don’t get me wrong. Accountability is vital. If someone does something unspeakably bad, they must be held accountable. That is a form of blame. Tracing the bad event back to the root cause. If that cause is found to be negligence or malicious intent, then blame can be assigned.

Where a good safety culture exists, as it often the case in civil aviation, then it is wrong to assume that undesirable outcomes can always be linked to a bad actor of some kind.

Human error is forever with us. Even with the absolute best of intent no one is immune from this pervasive creature. It can be illusive. There are environments where owning up to making mistakes is fine. Sadly, I’m sure it’s not uncommon to have worked in environments where such openness is punished. The difference between a good culture and a bad one.

One of my past jobs involved negotiation with a contactor. Every change that we made to a complex contact had a cost attracted to it. So, there was an understandable sensitivity to making changes. At the same time our customer for the product kept asking for changes. There’s nothing worse than being in a tense meeting with a contactor and having my boss pull the rug from under my feet. Seeking to blame a change on my error rather than a customer request. Introducing a voluntary reporting system in such an environment is pointless.

My message here is clear. Voluntary reporting in aviation is a powerful tool. Reports submitted by employees can offer insights that are not available by just looking at hard data. These reporting systems maybe required by regulation or company policy. However, without a good sound safety culture they can be all but useless. A safety culture that is defended and supported by employees and the senior management of an organisation.

Shifting Perspectives

If you write the perfect rule, you will get the desired outcome. Authoring a specification that is robust and watertight will assure success. Having the best possible plan will deliver the best possible results. All sounds reasonable – doesn’t it? It’s not surprising that someone like me, having been schooled in project management, and working in engineering, would have a rational and systematic approach to problem solving. A proven highly successful way of implementing complex technical projects and delivering successful outcomes.

As an analogy I’ll start with mathematics. Nature is a curious beast. What we lean about complex systems is that what happens is highly dependent upon a start point. The initial conditions. Graduate level mathematics about control systems with feedback show that their behaviour changes a lot with a change of initial conditions. So, it’s reasonable to extend that to a systematic approach to just about anything. It’s often true.

Fail to plan – plan to fail. That idiom is a simple few words to sum up this cause and effect. Used by famous names and often quoted. Management training books are littered with this notion.

20-years ago, my team introduced the first European Aviation Safety Plan[1]. This initiative was built around the idea that to achieve a common objective a plan is the best and quickest way to get there. A roadmap, a pathway, a strategy, call it what you will.

Start by identifying problems and then propose a fix for each one. Not all problems but the ones that fit that awkward Americanism – the low hanging fruit. Namely, the biggest problems (fruit) that can be solved with the least effort (easily picked).

Here’s where I’ve changed your mind. Maybe not changed in a dramatic sense but shifted perspective. It’s essential to have a plan, even if it’s just in my head, but it can be overstated as the most important part of a process of change.

The Plan, Do, Check, and Act (PDCA) cycle, starts with a plan. It must start that way. However, each of the four steps is equally important. Seems obvious to say. Even so, it’s often the case that a press release, or alike, will state – we have a plan, roadmap, pathway, strategy, as if that’s the job done.

Management teams will smile with a sense of achievement and show off their plans. A decade down the line that celebration might seem less momentous as the “do” part of the process turns out to be harder than anticipated.

This basic model for systematic change is a good one. Where I’ve changed my emphasis is in the distribution of effort. Don’t put all available energies into constructing the perfect plan. Yes, the initial conditions are important but they are not everything. The key part of the process is the cycle. Going around it with regularity is a way of delivering continuous improvement. Afterall, when it comes to a subject like aviation safety, that’s what’s needed.

National Digital ID: Balancing Security and Liberty

We are in an age where identity is as important as it has ever been. Those line of demarcation that put us in one camp or another. It’s not a simple subject give the myriads of different combinations and permutations of distinct categories that can describe a person.

Without a doubt, I’m English, British, and European. A West Countryman, a husband, a graduate, a homeowner, a taxpayer, a liberal, an engineer and a gardener to name a few.

So, what of the current debate about the merit of identity cards or their digital equivalent. I remember, more than 15 years ago, the debate that surrounded this subject. Saying, as a Liberal Democrat I was against the introduction of ID cards as a matter of principle. A matter of principle seems like it should be an immovable statement. However, that which was a matter of principle in the context of the times does warrant revisiting.

It’s a transformation that was allowed to sweep much before it. From a paper-based analogue world full of mechanical processes to a ubiquitous high-speed digital one that has made life unrecognisable from the 1980s/90s. Digitisation is as much a social change as it is a bureaucratic change.

Past agreements range from the assertion that it will be impossible to control illegal migration without ID cards to the fear of big brother tracking every stage of our lives from cradle to grave. What’s moved on is the context within which arguments for and against are conducted.

A starting position is that each of us has multiple identities. It’s undeniable that these exist and they impact our daily lives. Some of these identities entitle us to specific privileges. This means permitting our access and restricting or stopping others. This can be as simple as a workplace security badge that allows access to a building.

A State-run identity recording system is not a universal cure all. Also, a State-run ID card and national database system has the potential to fundamentally change the relationship between a Citizen and the State. I could say that there’s nowhere to hide. This is not a subject to go into with one’s eyes closed. The operational and associated implementation costs would be significant. Not to mention ongoing maintenance. These must be weighed against the benefits that might be accrued. I hope this becomes a rational discussion where costs and benefits are studied, published, and debated.

Can a national digital ID system prevent terrorist attacks, illegal immigration, identity fraud, and human trafficking? I don’t know. I do know that it will not be perfect.

On the political side, will people feel more secure and that State benefits or services are more fairly distributed as a result? That’s a big question.

To work effectively such a system will need to be required to by law. How much will that nibble away at the intrinsic perception of British liberty that we continue to hold? Will there be a backlash against a State that seeks to acquire more leavers of control?

My view is that the mandating of a national digital ID system needs to be balanced with a better clarification of the rights of citizenship in Britan. Without a written constitution there remains the vulnerability that a government of an extreme political type could misuse this innovation.
