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.

Europe Day Highlights the Need for Unity

Keeping the peace is never easy. There’s an irrational propensity to conflict in human nature. Keeping the peace is not a passive task. First, it requires communication and engagement. When those two go, trouble is not far behind. It’s by expressing concerns that each side knows where the other stands. Escalation can come when ignorance and propaganda take over.

After the second world war, institutions were established to ensure that communication and engagement became a non-stop affair. With only a small number of exceptions, the countries of the regions of the world engaged in these institutions. Those measure have contributed to making a more prosperous world.

“Never again” are two words that refer to the atrocities of war. The moto is to remind everyone that the worst can and does happen, and that perpetual effort is needed to ensure that history does not repeat itself. The concept of “lessons learned” is essential for safety and security. This is as much true for micro day to day activities as it is for the macro events that shape the path global ahead. Taking teaching not from narcissistic demigods and snake oil salesman but from the pages of history. Appeasing tyranny is not an option.

This week has been a reminder of the lessons learned from the world wars. For most people it’s been a continuing commitment to ensure such events never happen again in Europe. Sadly, let’s not be coy. Despite an overwhelming desire for peace, conflict in still Europe is a reality. But the lesson is there in black and white, appeasing tyranny never works.

Today, Friday 9^th May is Europe Day. That’s because a speech by Robert Schuman[1] changed the course of European history on this day. Five years after the war in Europe had come to an end, he put forward a proposal that would make a future similar conflict impossible. The idea was to create an interdependence that would secure peace, unity and solidarity.

It worked. His proposal led to the creation of a European Coal and Steel Community. That measure lay solid foundation for what would later become the European Union (EU). Behind this is move is the echo of “Never again”. Europe has seen centuries of war. This was a moment in time to bring that to an end.

For now, 75-years on, this has been a success. It’s not a regional project with a defined end, even if it has a defined beginning. Where the EU chooses to go next is in the hands of its Member States and its citizens. Changing the course of European history doesn’t stop because the EU exists. Without the cooperation and dialogue, it provides there’s always a chance that ancient rivalries will be reignited. In fact, unscrupulous right-wing politicians[2] are trying to do that just now.

Sadly, in the UK, we stand on the sidelines, looking across the water at continental Europe. Brexit has done a great deal of damage. But as I have said, nothing is static, the world is entering an ever-uncertain phase. The opportunity for the UK to restore EU relations is open. I see the wisdom in the words of the Governor of the Bank of England. He has said the UK now needs to “rebuild” Britain’s relationship with the EU. Amen to that.

Cities Shaped by War

War is failure. Humans being quick to aggression, possessive and slow to reconciliation, it’s plagued every corner of history. Reason to go to war can be imperial, territorial, moral or ethical. In a democratic society, defeating an evil becomes an overwhelming imperative. That was certainly the case in the six years of the second world war. This week, it’s time to look back. To recollect the impact of the world war. To remember the sacrifice and suffering. To be thankful for the last 80-years years of relative peace in Europe.

For me these recollections take me to the experience of living in two cities. Cities on different sides of past conflicts. Severely damaged by the conflict. Targets because of their civic and industrial strength. Both cathedral cities with an ancient heritage.

My student life was spent in Coventry[1]. A decade of my working life was spent in Cologne[2].

Arriving as a fresh-faced student in the heart of the industrial Midlands, the architecture of Coventry city centre was so striking. It was that post-war vision of rebirth at a time when economic decline had set in. With an inner ring-road that was like a go-cart track, 50s style concrete avenues, windblown and neglected, there was little of the Medieval splendour of the pre-war city remaining. Standing proud in the middle of it was, and is, the skeleton of the old cathedral and the new one that ascended like a phoenix from the flames of war. Well worth a visit, the cathedral built in the 60s is a wonderful modern design. It plays with light and space to elevate emotions. A sign that we have a great capacity for reconciliation and regeneration.

Moving on just over 20-years, my encounter with Germany’s fourth largest city was full of hope and optimism. Based in Cologne, I experienced a city with even deeper roots than Coventry. Ironically, it was the destruction of the war that uncovered much of the Roman remains on display. At Cologne’s heart is a magnificent gothic cathedral that is more dominating of the landscape than perhaps ever it has been. Here the citizens of the city took a different approach to post-war rebuilding. Not so much embracing everything that was new, although there’s quite a bit of that approach, but reconstructing the old city in its original style. The culture of the city survives in the traditions of the annual carnival.

These two European cities have taken different paths. All the same, there are threads of common experience. Both have seen industrial decline and a search for a better future to thrive and grow. Both are distinctive and culturally colourful. Both carry the baggage of a brutalist architecture that was fashionable on the drawing boards of the late 1950s.

Visting the past in museums and walking the streets the marks of the last war are there to be seen by everyone. Passed by every day. Yet, mostly ignored in the humdrum of commuting and the busy obsession we have of staring at a “mobile” or call it a “handy”. Now and then it’s as well to look up. To look and see the bullet marks on stone structures, the nicely arranged medieval or Roman stones and cobbles, or the conserved streets that contain the ghosts of past generations. For good or ill, war has shaped the world we inhabit.

Peace is a far far better condition. I think of the “Coventry Cross of Nails[3]” as a symbol of reconciliation and peace. Let’s not forget.

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.

Communication Prevents Disasters

It’s often forgotten that there’s a need to repeat messages. We are not creatures that retain everything we see and hear. There are exceptional people, it’s true, those who cram away facts and have an amazing level of recall. Often that’s my reaction to watching students leading teams on University Challenge[1]. How on earth do they know those obscure facts?

Most of us do not respond well to those who say, “Well, I told them once. I’m not going to tell them again.” That line is probably one of the most misguided utterances a teacher can make. Like it or not, this approach is part of our heritage. Past ages, when deference was expected, listening was mandatory, and misremembering was entirely the listener’s fault.

We’ve had a cultural shift. Our complex technological society doesn’t work in a command-and-control way. Too many disasters can be traced to miscommunications and misunderstanding. Now, the obligation exists on those delivering a message to go some way to ensure that it’s received with a degree of comprehension. That’s when repetition has a role to play.

One of the pillars of Safety Management Systems (SMS) is Safety Promotion. It’s the Cinderella of the aviation safety world.

Why do I say that? Experience for one. It’s much easier to get policy made and funding for the “hard” sciences like data acquisition, analysis and decision-making systems. These are often perceived as providing tangible results. Actionable recommendations that satisfy the need to be recognised as doing something. Even if that something is questionable.

Communication is key to averting disasters. It’s no good having pertinent information and failing to do anything with it, other than file it. The need to know is not a narrow one. Confined to a specialist few.

Let’s go back to 2003 and the Space Shuttle Columbia accident[2]. This craft was destroyed in a disaster that claimed the lives of its crew. The resulting investigation report is extremely compressive, if slightly overwhelming, but it has some key points to make.

To quote, “That silence was not merely a failure of safety, but a failure of the entire organization.” [Page 192]. In other words, the hidden concerns and internal machinations of an organisation can smother safety messages and led to failure. Since 2003, it’s sad to say that there are multiple occasions when what has been learned has been ignored. The impact has been devastating.

So, to shape the future let’s remember the Cinderella of the aviation safety. Discovering problems is not enough. It’s vital that practical solutions and good practice gets promoted. That needs to be done forcefully and repetitiously.

My First US Adventure

Let’s wind the clock back. My first trip to the US. It was a big adventure. One that I’d recommend to anyone in their 20s. The trip was a Pam Am fly-drive affair. A travel package that took me and three friends from London Heathrow to Seattle and back. In 1981, I had no idea that I’d be returning to Seattle numerous times in the following decade.

I keep a personal flight logbook. It’s a simple way of keeping track of the dates, times and places. Memory can be unreliable. When 40 years or more has past recollections of individual trips get jumbled up. Although this one is difficult for me to mistake.

We took off in the afternoon and flew across the Atlantic on flight PA 123. Slightly being in awe of the mighty Boeing 747-100. It was the largest aircraft doing that route on a regular basis.

Sadly, the Lockerbie bombing occurred 7-years later to a similar transatlantic Pan Am flight. The airline that brought the Boeing 747 to life didn’t survive after that tragic event.

One of the advantages of being a sandwich student was the ability to earn. To put some money away. To have the funds to plan an exploration like this trip without depending on the bank of mum and dad. To keep the costs down the four of us shared a car, the driving and the motel rooms along the way. In fact, we had a detailed itinerary that didn’t leave much slack time at all. Our travel planning was meticulous. I’d even arranged to visit an offshoot of the Plessey company in the Los Angeles suburbs. It was a real eyeopener. A maker of precision metals for the aerospace industry.

We arrived in Washington State only a year after the deadliest volcanic eruption[1] in US history. Naturally, being the students we were, we drove as close to the devastated area as the open roads would let us. I took pictures of that too. Views of forests felled like matchsticks.

We packed an enormous amount into August 1981. Returning to our final year as soon as we got back. This trip always reminds me that if you plan well and are determined enough you can do a hell of a lot in a short time. We drove over 6000 miles and took in a lot of the West Coast.

Tragic Helicopter Crash

The record of sightseeing helicopters is not a good one. In the most recent case 6 people perished as helicopter crashed into the Hudson River in New York City. It’s with a heavy heart that I offer my condolences to the family and friends of those involved. These are devastating events for all concerned.

It’s certainly far to early to say why this helicopter fell from the sky. Eyewitness reports suggest a catastrophic occurrence. Also, that the helicopter tumbled and hit the water inverted. Again, suggesting an occurrence where the pilot had no opportunity to avoid the outcome.

Initially, the indications are that the local weather was not a significant factor in the accident. Also, reports are that no other aircraft was involved. In this fatal accident the US National Transportation Safety Board (NTSB) will be on the scene as they manage the technical investigation. They have already published initial information.

Given the size and nature of operations there will be no Flight Data Recorder (FDR) installed on this helicopter. There is a strong argument for requiring light weight flight recorders on small helicopters. It will be interesting to read of what electronics are recovered from the accident site. Images from a mobile phone may be most useful to the investigators.

The helicopter’s maintenance records will be reviewed for indications of mechanical problems. However, it is highly unusual for a complete rotor system to fall apart in flight. Mechanical failures often have some precursors that give an indication that all is not well.

The list of Bell 206 type helicopter accidents and incidents is long[1]. That’s not an indicator of their relative safety. This is a popular single engine small helicopter with a long history. Both civil and in other variants, military. First flight dates to 1966. It’s going back a while, but I clearly remember a sightseeing flight I took on such a helicopter back in the 1980s.

This type of small helicopter is often operated in difficult conditions. They have the advantage of being highly maneuverable. However, there are maneuvers that can case serious problems. The term “mast bumping” was used by the US Army[2]. In the worst cases this results in catastrophic occurrences.

One of the factors in such accidents and incidents is a significant change in the helicopter’s center of gravity and an inappropriate response to that condition.

POST 2: Pictures of the recovery of the rotor system from the river suggest structural failure. It’s as if the rotating mechanical parts ripped themselves from the body of the helicopter. Bell 206 L-4 helicopter crash, Jersey City, New Jersey (April 10, 2025) | Flickr

POST 1: Social media is littered with theories, as per usual. One seems highly unlikely. Namely, fuel exhaustion. Another, concerning a strike of a flock of birds over the river is worth investigation. In that possible case evidence will surely be easily uncovered.

The Curious Case of Lists

How on earth does a humble soul like me make any comment at a time like this? Adding to the realms of things already said seems a bit pointless. We now have echo chambers sounding in echo chambers. Instead, I’ll take a sideways look. Mention one or two of the items that struck me during the week.

Penguins are getting a lot of Press. Ever since Trump decided to slap a tariff on an island inhabited by penguins there’s been a lot of speculations as to his ultimate motives. If I take Feathers McGraw as an example, I can well understand the need to make a pre-emptive strike against such a potentially villainous bird.

Of other notable penguins, I can only surmise that Trump has never heard of Pingu[1]. Now, there’s a subversive penguin if ever I saw one. He originated in Switzerland, which is strange to say the least.

I almost forgot another memorable fictional penguin of the past. A threatening comic character that combines menace with a gentlemanly swager[1]. One of Batman’s greatest foes. A well dressed master criminal unlike other criminals one might mention.

[1] https://youtu.be/yxqz9JqXdJU

I forgot it this year. Next year, I will pay attention to Penguin Awareness Day. 20 January might be winter to us but its summer to them. Birds that have the decency to dress up in black and white dinner jackets deserve some respect. I for one, will express my concern that the exports of our feathered friends may be taxed. Could it be that Trump is confused. Afterall the real penguins love the ice in the southern hemisphere. In fact, nowhere near Greenland.

“I’ve Got a Little List”. There’s a phrase that comes to mind. Lists, one in particular, does seem to have hit the News this week. I ask, why is there no modern-day equivalent of Gilbert and Sullivan? Accepted, companies do play with their songs and make words to fit the situation of the day[2]. There’s a great deal of scope for new lyrics.

The fabric of social media would rupture if there were no lists. I’m often entertained by an animation that shows a compilation of data as it ripples through the years. Something with colourful bar graphs that go up and down as the rank and order changes. A musical accompaniment that has no relation to what’s being presented. Lists are captivating. They spur a natural curiosity to look for the item of most personal interest. So, over time the economy of X or Y country goes up and then down and then up again. For sure, nothing stays the same for long. That maybe the moral of the week.

Exploring Sunday

To the rationalist everyday is the same. Earth turns on its axis. We all experience day and night. Day and night change as the season change. It’s all mechanical and predicable. Even the builders of Stonehenge knew that there was a rhythm to the year.

Last night, to mark that transition between the cold winter months and spring, the clocks went forward one hour. So, I’m already out of sync with my normal routine. Happy with it. Those extra hours of light in the evening are a great joy. Time to get the garden in shape.

This seventh and last day of the week, has a marker too. Christian communities see this day as a day to take stock, to rest. We don’t entirely observe that tradition anymore, but it is a different day. A day when life takes a slower pace.

If I go back to my youth, Sundays were distinct. The day was always a time set aside for visiting relatives. Now and then, a church or chapel service in the evening. West Country village life was one of compromises. We went backwards and forwards between the Church of England and a small Methodist chapel in an adjoining village.

Sunny spring and summer Sunday evenings could be unlike every other day. Until my parents gave up the dairy, and reliance on a cheque from the Milk Marketing Board[1], everything we did had to fit around milking time. Cows have internal clocks. They know when the time has come for milking.

Lighter spring evenings opened the opportunity to go visiting or, as we often did, going for a drive. All six of us would get packed into the family’s Wolseley 16/60. Dad would head off over the hills and vales of Somerset and Dorset to get some relief from the constant demands of the farm. Later on, the 16/60 was replaced by a newer bright white Wolseley 18/85[2]. A quite dreadful car to ride in. It was a time when the British car industry was desperately trying to modernise. The Japanese had started to produce cars that were starting to offer better value and reliability.

Cruising around the country lanes was not only an opportunity to get out and about, but this was also a way of looking over the hedges and surveying the landscape. Finding out what the neighbours were up to. Checking out some new farming venture that was being talked about at market. Criticising poor husbandry or the dereliction of what was once a “good” farm.

This childhood experience has left me with a curiosity. Could be inherited. That need to know what’s around the next corner or just over the brow of a hill. It’s imbedded. Naturally, that curiosity was stimulated by the unending variety of the topography. On my trips to America, it has always struck me that driving for miles and miles can be easy, but it takes a long way for the sights and sounds to change. Somerset and Dorset, and I mustn’t forget Wiltshire, have a world around every corner. Sundays were explorer days. Adventure days too.
