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.

The Legacy of Beeching

Two hundred years is a long time. No, it isn’t. William the Conqueror, that’s the sort of name politicians crave, called for the building of Windsor Castle in England. That means, almost but not quite, a thousand years of continuous use. I guess in 2070 there’ll be a big celebration of the achievements of the Normans. Certainly, seemed to impress US President Trump.

If I had a time machine one of the destinations that I’d consider is 1963 and maybe 1965. I’d take a mass of press clippings and audio recordings about inadequate rural bus services and the high-speed railway saga (HS2).

History has a way of condensing a whole succession of events into a few simple words. William was a conqueror, but 1960’s civil servant Beeching was an axeman. That can be said to be unfair, since he was mandated to produce a report and, in the context of the times, British railways seemed like they had overexpanded and wouldn’t be brought back into profitability.

This happened when I was a child. I can just remember on my way to primary school stopping at a railway crossing and waiting a steam train to pass. It could have been the milk train. At that time milk was transported from west country dairy farms, in churns, to the local milk factory. Then loaded onto a London bound train. All this activity disappeared as I grew up. It was displaced by road tankers forcing their way along country roads.

I was born in a small Somerset railway town. Got my first pay packet in that small railway town. Had a couple of weeks of my engineering apprenticeship in the former railway shed. Spent time in the small motorcycle shop next to the railway embankment.

Beeching’s reports resulted in thousands of stations and thousands of miles of railway line being closed. The Somerset and Dorset (S&D) railway line was one of those that vanished. It was on 6 September 1965, the consent for closure was issued for most of the railway line.

Strangely, it was a newly elected Labour government that promised to reverse railway closures that closed the railway. A campaign to save the line was lost. Now, I think, what if, what if the new government of 1964 had not been so beguiled by modern road building and the white heat of technology. The internal combustion engine and purveyors of tarmac had won the day.

My message is to commission reports with a wider remit than merely improving economic efficiency. It’s a concern that is as ap today as ever it was. State of the art technology is alluring. Sloganising it’s easier to say that we are moving forward to a new dawn than it is to say we will update and improve the machinery we already use. There are good cases for scrapping past ways and means. Surely, it’s as well to try to look beyond immediate pressures.

Had Beeching’s axe not been so readily swung then we’d have an alternative to ever more road building and the billions ploughed into it. Remember those feeble promises to invest in local busses to replace the lost trains. How such recommendations are so quickly forgotten.

What will we say about robotics and artificial intelligence in 60-years’ time. Or even 200-years’ time. If we are still here.

Exploring the Greatness of Great Britain

What’s great about Great Britain? GQ has asked this question[1]. Produced a nice article that looks at this subject with a cultural eye.

It’s a bit retro. When we (Brits) start talking about how great pubs are there’s a tendency to forget how many we have lost in the last decade. If we loved them so much, then more would have survived crushing economic pressures.

Brit pop was a wonderful surge in creativity that swept across the country in the 1990s. It was good – mostly. Riding that wave, because we are romantic souls about the past, are the band Oasis with their multimillion £ world tour. Accounts of which are tremendously positive.

I think I can take a position about what’s great about Great Britain. Having lived in Germany and travelled a bit, my perspective isn’t too insular or defensive.

Because we are no longer the world’s premier power and imperialism is a fading memory, we’ve shed the stiff upper lip and bowler hatted civil service bureaucrat image. It’s there in film and television to remind us of former times. It’s few who want to return to all that deep seriousness.

That seriousness is the burden that the US carries. If they send a gun boat somewhere it means business. For Brits it’s more a symbol of still being on the stage. Don’t get me wrong, as a country we box way beyond our size.

For all the right-wing jerks who parade around with false patriotism, our great strength is diversity. Having that legacy of the world map once having been painted in a great deal of red, we can now engage with multiple cultures and benefit from them all.

Number one of the lists of inherited advantages is being able to speak to the world. Not in their language but in ours. English doesn’t belong to the English any more, it belongs to the world. They amount to a lot; the times I’ve had fun reading Brussels English and being amazed at how it’s being used.

Pick a discipline. Science, technology, humanities, art, entertainment, there’s always a Brit that can be named as shaping the world. Influencing others and providing a spark that sets off a flame.

Now, being more parochial, I’ll look around me, in this town, and see a diversity of styles from punks who never stopped being punks to suited tie wearing customer service executives. Welly booted farmers in the town for a day to young gamers stuck to their small screens.

Sport is another anchor. If we (Brits) didn’t invent it, then it’s a derivative of something we did invent. Top that with the eccentricities from international tiddlywinks[2] to stone skimming. Despite the school of hard knocks we still value fair play.

Comedy is taking a downturn, but the British legacy is monumental. Irreverent, rebellious or intricate, often all three, even if we (Brits) do invite in the bland factory-made stuff from the US. In a unregarded small corner there’s a someone writing hysterical lines waiting to be discovered.

So far, as a nation, 2025 won’t go down in history as our best year. I’ve every faith that the best is still yet to come. Unlocking that dynamic zest, that quirky imagination, that complex amalgam happens several times every decade. Let’s hope the spark is just about to be set off.

Regulatory Insights

I can’t remember if my teacher was talking about maths or physics. His scholarly advice has stuck with me. When things get complex, they can seem overwhelming. Problems seem insolvable. So, it’s good to take a deep breath, step back and see if it’s possible to reduce the problem to its most basic elements. Do what could be called helicopter behaviour. Try to look at the problem top-down, in its simplest form. Break it into parts to see if each part is more easily comprehended.

Today’s international aviation regulatory structure, for design and production, follows the arrow of time. From birth to death. Every commercial aircraft that there ever was started as a set of ideas, progressed to a prototype and, if successful, entered service to have a life in the air.

This elementary aircraft life cycle is embedded in standards as well as aviation rules. Documents like, ARP4754(), Aerospace Recommended Practice (ARP) Guidelines for Development of Civil Aircraft and Systems are constructed in this manner. There are as many graphs and curves that represent the aircraft life cycle as there are views on the subject, but they all have common themes.

That said, the end-of-life scenarios for aircraft of all kinds is often haphazard. Those like the Douglas DC-3 go on almost without end. Fascinatingly, this week, I read of an Airbus A321neo being scrapped after only 6-years of operations. Parts being more valuable than the aircraft.

Generally, flight-time lives in operational service are getting shorter. The pace of technology is such that advances offer commercial and environmental advantages that cannot be resisted. Operating conditions change, business models change and innovation speeds forward.

My earlier proposition was that our traditional aviation regulatory structure is out of date. Well, the detail is ever evolving – it’s true. Some of the fundamentals remain. The arrow of time, however fast the wheels spin, mixing my metaphors, remains an immobile reality.

In airworthiness terms an aircraft life cycle is divided into two halves. Initial airworthiness and continuing airworthiness. This provides for a gate keeper. A design does not advance into operational service, along the aircraft life cycle, until specified standards have been demonstrated as met. An authority has deemed that acceptable standards are met.

I’m arguing, this part of the aviation regulatory structure is far from out of date. However much there’s talk of so called “self-regulation” by industry it has not come into being for commercial aviation. I think there’s good reason for retaining the role that a capable independent authority plays in the system. A gate keeper is there to ensure that the public interest is served. That means safety, security and environmental considerations are given appropriate priority.

To fulfil these basic objectives there’s a need for oversight. That is the transparency needed to ensure confidence is maintained not just for a day but for the whole aircraft life cycle. And so, the case for both design and production approvals remain solid. The devil being in the detail.

Flag Displays

Traveling here, travelling there, it’s not usual to see a national flag displayed. Whether it be on public buildings, airports terminals or stadiums it’s up there to celebrate belonging. National flags come out most often when major sporting events are underway. They appear and then disappear like a tsunami. It’s a field day for retailers. From the finest natural materials to the cheapest plastics, every size and shape is available.

I’ve kept a flags few, rolled up waiting for a special occasion. One Union Jack, a cross of St George, the European stars, a German one and a flag of the city of Cologne. I did have a Somerset County flag but now can’t find it.

Twice I’ve been to the last night at the Proms[1]. One of the fun parts of that evening is spotting the more unusual flags and trying to work out where they represent. Don’t tell me you know what the Northumberland flag looks like. I certainly didn’t until it was explained to me. By the way it looks like alternating red and yellow Lego bricks stuck together.

For me, as it is for most people, waving a flag is for a special occasion. Carnaval, a parade or Royal occasion. The Eurovision song contest, World Cup or Olympics. These are events where we come together as a community.

Frankly, going around and painting roundabouts red and white with the cross of St George, with cars whizzing around, is plain foolish. It detracts from the importance of the national symbol. What a grown man, in the recent News reports, thinks he’s doing with his tin of paint, I can’t fathom.

Flying Union Jacks, often upside down, from Motorway bridges is juvenile. Today, I saw one or two and it made me think that there’s likely three reactions.

One: ambivalence. That is, either not to notice or to ignore the display as much as ignoring the writing on the side of a large truck. Conveying no message other than what a waste of time.

Two: annoyance: That is, to go back to my point about degrading the symbol. Seeing the fixer as a pompous twat or intimidating bully with time on their hands. Stirring up political divisions for the sake of it.

Three: acclamation. That is, being distracted enough to put a big thumbs up to whoever bought the flag and tied it into position. On-board with plastering every road bridge with flags as an imagined rebellious act.

Doesn’t take much to figure out which one of those I might be. On this subject it’s as well to be as generous as possible. These acts of putting up flags for no reason obviously makes some people happy. Given that they are ranked number one in the world, I’d like to think that the flag waving is in support of England women and rugby union. Somehow, that’s a stretch given the utterances of the flag painters and the bandwagon jumping political stirrers.

Where public property is concerned it’s the duty of public authorities to take them down. Not to tolerate the defacing of public property. However, I can imagine this is just the provocation that some people are inviting.

Aviation Regulations Outdated?

Machines, like aircraft started life in craft workshops. Fabric and wood put together by skilful artisans. Experimentation being a key part of early aviation. It’s easy to see that development by touring a museum that I’d recommend a visit. At Patchway in Bristol there’s a corner of what was once a huge factory. In fact, somewhere where I worked in the early 1980s. Aerospace Bristol[1] is a story of heritage. A testament to the thousands who have worked there over decades.

Fabric and wood played part in the early days. The factory at Filton in Bristol started life making trams. An integral part of turn of the century city life. Carriage work brought together skilled workers in wood, metal and fabrics. It was soon recognised that these were just the skills needed for the new and emerging aircraft industry. The Bristol Aeroplane Company (BAC) was born.

It’s war that industrialised aviation. Demonstration of the value of air power led to ever more technical developments. Lots of the lessons of Henry Ford were applied to aircraft production. Factories grew in importance, employing a large workforce.

My time at the Filton site was in a building next to a hanger where the Bristol Bulldog[2] was originally produced. This was a single engine fighter, designed in the 1920s, in-service with the Royal Air Force (RAF).

Right from the start orderly processes and regulatory oversight formed part of aircraft design and production. The management of production quality started as a highly prescriptive process. As aviation grew into a global industry, the risks associated with poor design or faulty production became all too apparent.

In the civil industry, regulatory systems developed to address the control of design and production as two different worlds. Airworthiness, or fitness to fly, depended on having a good design that was produced in a consistent and reliable manner. So, now we have a regulatory framework with two pivotal concepts: DOA (Design Organisation Approval) and POA (Production Organisation Approval). It took about a century to get here. Now, these concepts are codified within EASA Part 21, FAA regulations, and other national aviation authorities’ frameworks.

Here’s my more controversial point. Is this internationally accepted regulatory model, that has evolved, conditioned by circumstances, the right one for the future? Are the airworthiness concepts of DOA and POA out of date?

This is a question that nobody wants to hear. Evolution has proved to be a successful strategy. At least, to date. What I’m wondering is, now the world of traditional factories and large administrative workforces is passing, how will regulation adjust to meet future needs?

Maybe I’ll explore that subject next.

Composition of the House of Lords

Composition of the House of Lords (HoLs) is a subject whereby a length thesis could be written every week. Our UK Parliament comprises of two houses of widely different nature.

Whenever and wherever there’s a public institution that depends upon appointments made by individuals with a vested interest, there’s problems afoot. A couple of minutes looking at what politician Boris Johnson[1] did while he was Prime Minister (PM) is enough to discredit the whole appointment system. Conservatives have had a habit of thinking of the HoLs as their own private thiefdom.

Please don’t believe I’m damming all the members of the “upper” house of Parliament. There are numerous honourable and capable members, dedicated to public service, who use their time to ensure their expertise is applied to the scrutiny of legislation. The scrutiny of legislation is vital. It’s even more vital because the “lower” house of Parliament, The Commons, does such a poor job holding the Government of the day to account.

If I look at the total votes cast and seats for each political party as a result of last year’s UK General Election[2]. Yes, it was only just over a year ago. Then the political parties with the most votes cast for them do have a claim for proportionate opportunities to recommend new members for the HoLs.

Trouble is that UK General Elections (GE) can come along like buses. There are years of turbulence when the electorate are consulted in quick succession. So, the idea that the composition of the HoLs should reflect the last result of a GE, that’s for the birds. An MPs term of office is that time between GEs. A member of the HoLs sits for much longer, a lifetime.

Should the HoLs reflect proportionally the composition of The Commons? Well, this one too would merely copy the turbulence of electoral fickleness to both parts of the Houses of Parliament. Not a good recipe for long-term stability and decent governance.

Please don’t believe, because of the above, I’m saying that electing the HoLs is a bad proposal. Quite the opposite. It’s that electing the HoCs and HoLs at the same time for the same term of office isn’t a good idea.

For the time being we have an important public institution that depends upon appointments. That quiet exercise of favouritism and gerrymandering is a legacy that resists reform. Will one enlightened day turkeys vote for Christmas? Better not hold our breath.

Do MPs Need Multiple Jobs?

It’s a question that has been raised time and time again. Is a Member of Parliament’s job a full-time job? What I mean is should an elected parliamentarian have more than one job? Do they need it?

Say, a journalist, presenter, documentary maker, official of a political party or union, company director or even a doctor.

There’s a repetitious ding-dong argument that goes on along the lines of – look at this example of great achievement and they were both occupied doing numerous jobs at the same time. Equally there’s the argument – look at this talented person who crashed and burned as a result over commitment and lack of attention to detail. Case by case examples can be found.

Sadly, a case built on individual examples of achievement, or the reverse doesn’t move things forward much. It’s a sort of selective sampling to prove a point. Fame and notoriety play a part too. When a hero, genius, guru or an influencer complex exists rules get bent. Mythical qualities can be ascribed to the subject of attention.

It’s true that some individuals have a capacity for work that goes way beyond the norm. An intellect that shines bright. A refreshing originality or perspective that changes the game.

Now, I’m a down-to-earth straightforward liberal. It’s does matter if you are a King or a Queen, an Olympic athlete or a massive titan of industry or a brilliant orator we are basically all the same. We see the sun rise and we see it set (weather dependent). We walk the same Earth. We are as likely to experience mental or physical challenges in life as any other human.

Back to my question. Is a Member of Parliament’s job a full-time job?

I’d start with the ways and means MPs get elected. It’s rare, if ever, that an individual is so well known that they step into a parliamentary seat with no affiliation, preparation, finance or support. Those people who provide such essential back-up have expectations. Expectations that the candidate, if elected, will dedicate their full-time efforts to their new role when in office. Not too much to ask, methinks.

Given that you and I have finite time and energy, playing multiple roles inevitably dilutes the time and energy available for any one role. Super humans haven’t been invented – yet. Whatever the myths. If a British MPs job is genuinely full-time then where does the extra time and energy come from to do another job?

By saying that an MPs job is not full-time, hasn’t the local electorate been sold a pup. I’m sure that when votes are cast in each constituency an expectation is set-up that a candidate will do a decent job if elected. A moral commitment is made as good as any binding contract.

I agree, that polarising this argument to the extreme isn’t helpful. MPs must manage their time and energy between home and work as most people do. I guess, what’s important is the prioritising of parliamentary duties to the degree they deserve. In other words not taking on equally demanding jobs at the same time.

Some of the cynicism towards British politics, that exists today, stems from MPs abusing their duty by prioritising income and / or notoriety in some other public facing role. Making being a Westminster MP merely a way of achieving other personal goals.

It’s not easy to make hard and fast rules for the above situations. A moral imperative should prevail. Sadly, it doesn’t aways go that way.

Desperate Politics

I’ll be generous and say that I don’t think Jenrick knows what he is doing. I’m taking about the Conservative British politician Robert Jenrick[1] who is, or has been by the time this gets out, the Shadow Lord Chancellor. Desperately ambitious politicians do all sorts of foolish things to get a headline. With the Conservatives in the doldrums the word desperate is truly applicable.

When looking at his published CV it’s reasonable to think that he might know something, at least the basics. At least some history. Yes, he’s just another well to do lawyer with an Oxbridge education but that’s so typical of Conservative British politicians. At least, he had some kind of working life before taking on parliamentary politics. Today, in Westminster he’s still a Johnny-come-lately having been first elected as a Member of Parliament in 2014.

Jenrick embraced social media to the extent that the right-wing of politics see him as a sort of top-ranking pinstriped influencer. Even if his amateur video antics look like an humourless Benny Hill dressed in a business suit and tie.

Today, he’s crossed a line. Stirring up hate at a time when problems need solutions not mindless rhetoric, is despicable. To say that “British women and girls[2]” are unsafe because of small boats is offensive propaganda designed to drive political debate into ever more nasty territory.

Yes, we have been here before in Britain. Conservative politician, Enoch Powell’s fiery “rivers of blood[3]” speech did a lot of harm, but it got him in the text books. Some do believe that the heart of the Conservative Party is English Nationalism. Wrapped up in the red and white flag of St George as an exclusive club of aggressive narrow-minded men and their followers.

I’ll be generous and say that’s not the conventional Conservative Party. At times of its greatest success, and let’s face it, that political party has been highly successful in winning elections, it’s been a broad church. A diverse party that has encompassed a wide range from woolly liberals to traditional imperialists.

If Jenrick thinks that jumping on bandwagons and stirring up hatred is the way to go he’s foolish. We are not in the 1930s, or even the 1960s, this is a new age and a challenging one at that. Social media was supposed to be a great educator and liberator. In some ways it is but within its walls are pits of despair and stinking wells of polarisation and Xenophobia.

Addressing the public disillusionment that exists by pointing the finger at one group or other as being the root of all our problems is totally mindless. It only seeks to elevate the profile of minor demigods and snake oil salesman (conmen).

Inflammatory speeches get headlines; there’s no doubt about that sad fact. For a moment eyes turn to the speaker, but history turns away from them. In comparison with the 21st century challenges the country faces the so called “small boats” are a small one. Real solutions to real problems are needed not hideous grandstanding.

Why 12,500 Pounds?

Regulation is a strange business. It often means drawing lines between A and B. Bit like map making. Those lines on a map that mark out where you are and the features of the landscape. You could say that’s when all our troubles start but it’s been proven unavoidable. As soon as our vocabulary extends to words like “big” and “small” someone somewhere is going to ask for a definition. What do you mean? Explain.

For a while you may be able to get away with saying; well, it’s obvious. That works when it is obvious for all to see. An alpine mountain is bigger than a molehill. When you get to the region where it’s not clear if a large hill is a small mountain, or not then discussion gets interesting. Some say 1000 ft (about 300 m) others say much more. There’s no one universal definition.

[This week, I drove through the Brecon Beacons. Not big mountains but treeless mountains, nevertheless. Fine on a clear day but when it rains that’s a different story. This week Wales looked at its best].

Aviation progressed by both evolution and revolution. Undeniably because of the risks involved it’s a highly regulated sector of activity. Not only that but people are rightly sensitive about objects flying over their heads.

For reasons that I will not go into, I’ve been looking at one of these lines on a regulatory map. One that’s been around for a long time.

I cannot tell you how many discussions about what’s “minor” and what’s “major” that have taken place. That’s in terms of an aircraft modification. However, these terms are well documented. Digging out and crewing over the background material and rationale is not too difficult, if you are deeply interested in the subject.

The subject I’m thinking about is that difference between what is considered in the rules to be a “large” aeroplane and a “small” aeroplane. Or for any American readers – airplane. So, I set off to do some quick research about where the figure of weight limit: maximum take-off weight of 12,500 pounds or less originated for small airplanes (aeroplanes).

I expected someone to comment; that’s obvious. The figure came from this or that historic document and has stuck ever since. It seems to work, most of the time. A confirmation or dismissal that I wanted addressed the question, is the longstanding folklore story is true. That the airplane weight limit was chosen in the early 1950s because it’s half the weight of one of the most popular commercial transport aircraft of that time.

There is no doubt that the Douglas DC-3[1] is an astonishing airplane. It started flying in 1935 and there are versions of it still flying. Rugged and reliable, this elegant metal monoplane is the star of Hollywood movies as well as having been the mainstay of the early air transport system is the US. Celebrations are in order. This year is the 90th anniversary of the Douglas DC-3[2].

What I’ve discovered, so far, is that the simple story may be true. Interestingly the rational for the weight figure has more to do with economic regulation than it has with airplane airworthiness. The early commercial air transport system was highly regulated by the State in matters both economic and safety. Managing competition was a bureaucratic process.  Routes needed approval. Thus, a distinction established between what was commercial air transport and what was not.

POST 1: There is no mention of 12,500 pounds in the excellent reference on the early days of civil aviation in the US. Commercial Air Transportation. John H. Frederick PhD. 1947 Revised Edition. Published by Richard D. Irwin Inc. Chicago.

POST 2: The small aircraft definition of 12,500 pounds max certificated take-off weight first appears in US CAB SPECIAL CIVIL AIR REGULATION. Effective February 20, 1952. AUTHORIZATION FOR AIR TAXI OPERATORS TO CONDUCT OPERATIONS UNDER THE PROVISIONS OF PART 42 OF THE CIVIL AIR REGULATIONS. This was a subject of economic regulation in the creation of the air taxi class of operations.
