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 Impact of the English Civil War

Yesterday afternoon, I met King Charles. No, not the one who lives in Buckingham Place. No, not the one who hide up a tree. No, it was Charles I. Or at least a man dressed as Charles I.

Reasonably you might say, didn’t that King have his head cut off a long time ago? A lot depends on any recollection of English history you may have. It’s not a part of history that is taught in the national curriculum. Which is odd when considering how important it is.

Shaw House[1] is a beautiful Elizabethan building that has seen a great deal of history. In the 17th Century an English Civil War battle was fought there, and in the surrounding area.

In Newbury, 1644 was a turbulent time. As I understand it, the civil war that was raging all around could have been brought to a swift halt. King Charles and his forces, the Royalists, facing defeat, fled in the dark of night and made their way to Oxford. Thus, the Parliamentarian forces were left with a pyrrhic victory.

Eventually, the Parliamentarian forces succeeded. Charles I was tried, convicted, and executed for high treason in January 1649. The bloody execution of the war left a scar on English society. Brother fought brother. Families were torn apart. Nowhere was left untouched by the conflict.

The events in Newbury led to the formation of the New Model Army in 1645. Parliamentarian success may be traced to that decisive reorganisation.

The Earl Rivers Regiment Muster (Members of The Sealed Knot[2]) is a group of reenactors who bring the 17th Century back to life in the 21^st Century. So, my day out at Shaw House was an immersion in times long past. People dressed up, showing off swords, muskets and pikes is entertaining and, without doubt, an important reminder of why today’s society is the way it is.

This was the time in English history when Parliament gained its supremacy. No more would the divine rights of Kings rule the English people. It’s true that the English republic didn’t last long but the supremacy of Parliament stuck.

Along with the re-enactments of battles there’s an exploration of how life once was. Exhibits of tradesmen and women the civilians who accompanied the armies. Reliving history by staging events beings alive the country’s past struggles. It’s a good reminder that conflict is ever with us.

By the way, if I had to choose a side, I surely would have been a Roundhead. The Royalist may have been said to be romantic, but they were on the wrong side of inevitable change.

Spectacular Sighting

There’s steep hills. Some more interesting than others, you might say. In my youth this one was known for the road that climbed the hill. That’s the B3081, if you want the detail. It’s an opportunity to journey through wonderful English countryside. The area being Cranborne Chase, a protected landscape.

Zigzag hill was great fun for us as children. Probably not so much fun for my parents as our jet black Wolseley16/60 strained to get around the corners and climb to the top. The car packed with the six of us. This was a route we’d take to get from home to Bournemouth, and the seaside.

On the way, I remember the finger post signs to Compton Abbas Airfield[1]. My thought being what an interesting place for an airfield, right up here high on the chalk hills. Looking down on the surrounding Dorset countryside and the town of Shaftsbury.

Normally, I have to go to flying displays to see historic aircraft fly. This Sunday afternoon, I travelled no further than my back door. Sitting outback in the steaming 30C-degree summer weather all I had to do was look-up. Not that I’d planned to look skyward.

That doesn’t happen every day. First there was a distant rumbling sound. Then it developed into the hum of multiple piston engines. It’s only when the distinctive sight of a Lancaster bomber appeared over the roof of my house did all become clear what was happening.

As soon as I fixed my eyes on the aircraft it was already off over the garden and out across the neighbouring field. This was Avro Lancaster PA474 passing right overhead[2]. It was heading off in a north easterly direction at a notably low altitude. Quote a spectacular sight.

I had to do a little research once the aircraft had disappeared over the horizon. Looking at what was happening on Sunday, I assume it was flying back from Compton Abbas Airshow[3] to its home in Lincolnshire. Given the high summer weather, this was a great day for flying.

This Second World War heavy bomber first flew in 1941. It’s part of the Battle of Britain Memorial Flight (BBMF), based at RAF Coningsby. It’s the only Avro Lancaster that remains airworthy and flying in the UK. It’s only recently returned to the air after a tragic accident involving the BBMF.

Later in the day, off in the distance, looking north, three other historic aircraft trundled across the sky. After dark, with the heavens clear, I caught the Perseid meteor shower. So, for watchers of the skies, 11^th August was a noteworthy day.

Mars steps

It’s strange what thoughts circulate in my head. If I was to say what kicked this off it was probably the story of the Preet Chandi[1]. It’s inspiring how some people see a challenge and just get up and throw themselves into overcoming it. Her commitment and determination are impressive. She was recounting the how and why of her striking endeavours on the radio. What’s much less inspiring are a some of the moronic comments that the web throws-up about her achievements. I hope she continues to take on great challenges and sweeps them aside.

Exploring and going that extra mile is built into the fabric of being human. Fine, it’s not for everyone but that’s no surprise given that there are 8 billion of us on this planet. A magazine popped through my letterbox this week speculating on what Earth will be like when that number gets to 10 billion people. Don’t worry it’s not all doom and gloom. It’s just that the world will be a very different place by the time we get to 2050. Wow, if I stay healthy, I might still be around.

A lot of public policy of the moment seems to be resisting this reality. Honestly building barriers and walls will do nothing whatsoever to build a better world. Cultivating political anxiety and fears about the future is the maddest short-termism that can be imagined. But sadly, there’s a lot of it about. It’s fashionable in the mature democracies around the globe.

Humanity has an endless list of “challenges” and opportunities ahead. Now, I don’t what to sound too much like the Musk man but we’ve a great deal to do off the planet. What we’ve achieved so far is chicken feed in respect of what we have the potential to achieve.

The big one, that taxes the imagination of writers and futurologists is what do we do about our sister planet: Mars. It’s impossible to ignore. It’s not that far away when compared with other distances in space. It’s intriguing in that it was once a water world. Like Earth.

Today, it’s a planet inhabited by robots. The only one we know that is so populated. Rovers drive around sending pictures back of a desolate barren landscape that has an eery beauty. So much of what we know about the place has only been discovered in the last decade.

Human exploration is natural and normal. Do we leave it to robots? Afterall they are becoming ever more sophisticated. Or do we plant boots on the ground and go there to explore in the way we have throughout the Earth. Well, except for parts of the deep ocean.

Here’s what crossed my mind. Just as Polar Preet, broke two Guinness World Records on her journey, so the incentive to be the first person on Mars is something that will land in the history books. The name of the person who makes those steps will echo through the centuries ahead. So, the trip to Mars will not need an incentive. The drive to do it, at almost any cost is already hanging in the air. What’s more complicated is the journey back to Earth. Going on an expedition has a clear goal. Getting back from an expedition has a different goal.

Being someone who recognises the benefits in the reliability of redundant systems it occurs to me that a mission to Mars needs two ships and not one. Both traveling together to the planet. One can be simple and utilitarian. That’s the one crewed as the outward-bound ship. The other, the homeward ship needs to be autonomous, secure and even luxurious. That way the hardest part of the journey, coming back, can be made easier and more likely to succeed.

Democracy

It’s one thing to talk about elections in theory it’s another to talk about them in practice. Only one person knows when the next UK General Election will be held. It’s the privilege of one person to say so. Since the UK gave up on fixed terms, power rests with the Prime Minister.

The Fixed-term Parliaments Act 2011 set a five-year interval between ordinary general elections[1]. The next UK General Election would have been scheduled to take place on 2 May 2024. Now, all of that has gone, within the life of a Parliament, it’s for one person to call a General Election at the time of their choosing. Imagine a race where one competing athlete gets to fire the starting gun. There’s no role for Parliament in deciding when a UK General Election will be held.

What we do know about this year is that there will be European Elections held between 6^th and 9^th June. I would say, mark the dates on your calendar. In fact, I will say mark the dates on your calendar, if you’re a European citizen living and working in the UK.

In this case citizens know when they will have the power to exercise their democratic right. They can plan accordingly. They can play a part in the process. They can weight-up the options.

Hundreds of millions of people in Europe can determine the nature of the next European Parliament. British citizens, because of Brexit will have no say in this huge application of democracy.

This is undoubtably a time when unity amongst European allies is of paramount importance. There are threats in numerous places around the globe. The need for close cooperation between the UK and EU is becoming ever more evident[2].

Foreign policy and defence interests have a great number of common threads that bind Europe together. Couple that with the uncertainty that exists in relation to future transatlantic links, then getting along better is an absolute necessity.

The naïve – go it alone – attitude of Brexiters has unravelled. A more pragmatic settlement is essential for mutual benefit as we move forward. Defence industrial collaboration is a must. It hardly needs to be questioned. Many of the large aerospace and defence enterprises that the UK military depends upon are established European companies. Collaboration is nothing new.

War in Ukraine came as an unexpected nightmare. This European conflict is likely to become ever more protracted. Much as the country might wish it was not so, there are limited ways in which the conflict can be resolved. Self-determination remains a core belief amongst western democracies. This must be backed up by force otherwise it becomes meaningless.

After Brexit, going forward the UK will have no say, and no veto, over how EU defence progresses. From here, it’s best that cooperation, collaboration, and influence go hand in hand.

Radio on the hill

We take radio for granted. I’m listening to it, now. That magic of information transferred through the “ether[1]” at the speed of light and without wires. This mystery was unravelled first in the 19^th century. Experimentation and mathematics provided insights into electromagnetics.

The practical applications of radio waves were soon recognised. The possibility of fast information transfer between A and B had implications for the communications and the battlefield.

It’s unfortunate to say that warfare often causes science to advance rapidly. The urgency to understand more is driven by strong needs. That phrase “needs must” comes to mind. We experienced this during the COVID pandemic. Science accelerated to meet the challenge.

It wasn’t until after he failed as an artist that Samuel Morse transformed communications by inventing the telegraph with his dots and dashes. There’s a telegraph gallery with a reproductions of Morse’s early equipment at the Locust Grove Estate[2] in Poughkeepsie. I’d recommend it.

The electromagnetic telegraph used wires to connect A and B. Clearly, that’s not useful if the aim is to connect an aircraft with the ground.

The imperative to make air-ground communication possible came from the first world war. Aviation’s role in warfare came to the fore. Not just in surveillance of the enemy but offensive actions too. Experimentation with airborne radio involved heavy batteries and early spark transmitters. Making such crude equipment usable was an immense challenge.

Why am I writing about this subject? This week, on a whim I visited the museum at Biggen Hill. The Biggin Hill Museum[3] tells the story the pivotal role played by the fighter station in the second world war. The lesser-known story is the origins of the station.

It’s one of Britain’s oldest aerodromes and sits high up on the hills south of London. Biggin Hill is one of the highest points in that area, rising to over 210 metres (690 ft) above sea level.

It’s transformation from agricultural fields to a research station (south camp) took place in 1916 and 1917. Its purpose was to explore the scientific and technical innovations of that time. Wireless in particular. 141 Squadron of the Royal Flying Corps (RFC) was based at Biggin Hill and equipped with Bristol Fighters.^[9] RFC were the first to take use of wireless telegraphy to assist with artillery targeting.

These were the years before the Royal Air Force (RAF) was formed.

100 years later, in early 2019, the Biggin Hill Museum opened its doors to the public. It’s a small museum but well worth a visit. I found the stories of the early development of airborne radio communications fascinating. So much we take for granted had to be invented, tested, and developed from the most elemental components.

Comms

The long history of data communications between air and ground has had numerous stops and starts. It’s not new to use digital communications while flying around the globe. That said, it has not been cheap, and traditional systems have evolved only slowly. If we think Controller Pilot Data Link Communications (CPDLC)[1] is quite whizzy. It’s not. It belongs to a Windows 95 generation. Clunky messages and limited applications.

The sluggishness of adoption of digital communications in commercial aviation has been for several reasons. For one, standardised, certified, and maintainable systems and equipment have been expensive. It’s not just the purchase and installation but the connection charges that mount-up.

Unsurprisingly, aircraft operators have moved cautiously unless they can identify an income stream to be developed from airborne communication. That’s one reason why the passengers accessing the internet from their seats can have better connections than the two-crew in the cockpit.

Larger nations’ military flyers don’t have a problem spending money on airborne networking. For them it’s an integral part of being able to operate effectively. In the civil world, each part of the aviation system must make an economic contribution or be essential to safety to make the cut.

The regulatory material applicable to Airborne Communications, Navigation and Surveillance (CS-ACNS)[2] can be found in publications coming from the aviation authorities. This material has the purpose of ensuring a high level of safety and aircraft interoperability. Much of this generally applicable material has evolved slowly over the last 30-years.

Now, it’s good to ask – is this collection of legacy aviation system going to be changed by the new technologies that are rapidly coming on-stream this year? Or are the current mandatory equipage requirements likely to stay the same but be greatly enhanced by cheaper, faster, and lower latency digital connections?

This year, Starlink[3] is offering high-speed, in-flight internet connections with global connectivity. This company is not the only one developing Low Earth Orbit (LEO)[4] satellite communications. There are technical questions to be asked in respect of safety, performance, and interoperability but it’s a good bet that these new services will very capable and what’s more, not so expensive[5].

It’s time for airborne communications to step into the internet age.

FR4978

The case of the forced diversion of Ryanair flight #FR4978, a commercial passenger aircraft over Belarus on Sunday, 23 May 2021, is a matter for grave concern.

So, what’s the problem? A civil aircraft with passengers on-board, on a scheduled flight, flying over a sovereign State was diverted because of an alleged terrorist threat. Aircraft lands safely and in the end most of the passengers continue to their intended destinations.

Well, the case of the forced diversion of Ryanair flight #FR4978, a commercial passenger aircraft over Belarus on Sunday, 23 May 2021, is a matter for grave concern. The aircraft was carrying European citizens and residents between two European Union (EU) capitals.

The track of the Ryanair flight FR4978 from Athens (ATH) to Vilnius (VNO) was posted on Twitter[1]. The Boeing 737-800 was diverted to Minsk in Belarus whilst it was about to start its approach to Vilnius airport in Lithuania. The Ryanair flight maintained 39,000 ft toward Lithuania before beginning a diversion about 73km from VNO and only 30 km from border. The Polish registered Boeing passenger aircraft (SP-RSM) was forced to land in Belarus.

More than 5 hours after the landing of flight FR4978, the aircraft remained on the ground in Minsk. Whilst the aircraft was on the ground the Belarusian authorities detained opposition activists, Raman Pratasevich and Sofia Sapega.

Was the aircraft hijacked to go to Minsk? Well, there’s no report of force being used on-board the aircraft, so strictly speaking this may not be a hijacking. The mystery deepens when considering that if the alleged terrorist threat was credible, it would have been far safer to continuing into Lithuanian airspace and land at the intended destination.

Also, there’s the Belarusian military fast-jet aircraft (MIG 29) that accompanied flight FR4978. This could be considered aggressive intimidation of the Ryanair flight crew. It certainly limited their flight’s options in respect of the situation. The military interception of a civil aircraft for political reasons is a serious act and one that can put the safety of passengers in peril. So, whether it’s called a “forced diversion” or a “State Hijacking” it could be in contravention of the Chicago Convention. That’s the basis on which international civil aviation is normally conducted.

It’s now clear that the International Civil Aviation Organisation (ICAO)[2] will carry out an independent investigation into this Ryanair flight[3]. Strong condemnation has come from the European Union (EU)[4]. The aircraft operator, the State of Registry, and many of the passengers were from EU Member States.

If the investigation concludes that officials in Belarus faked a bomb threat to divert this Ryanair flight for political purposes, then this is a gravely troubling act that has horrendous implications for international civil aviation. No other authorities had knowledge of a bomb threat to this Ryanair Athens-Vilnius flight. The Greek Civil Aviation Authority, as the aircraft took-off from Athens, has stated that it received no bomb warning.

This event is an attack on European democracy, freedom of expression, freedom of movement and safety. The Belarus authorities need to immediately release Raman Pratasevich and Sofia Sapega.

Update 2: Simillar thoughts: The interception of #Ryanair Flight #FR4978 – legal or not, carriers have been put on notice.

Brexit & Aviation 66

The simple phrase to “kick the can down the road” has been in use in political language for a long time. It means to put-off work on an important issue for a later date. When faced with an apparently insurmountable problem it’s just one of the tactics that can be used. Often the hope is that the passage of time will yield new solutions or change the environment sufficiently for an existing solution to become viable. Guess what? The longer the clock runs the more dangerous this short-term tactic becomes. If there’s a deadline looming for the delivery of a project or a hard and fast legal barrier sitting – immovable, then this is when the situation gets tense and the risks of complete failure escalate.

35 days on the clock. There’s now an expectation that Prime Minister May will ask for a 3-month extension to the Art 50 timings. This is an optimistic scenario but it’s the only practical way that legislation can be passed should a vote in Parliament given the Government a green light to proceed.

Brexit could be called off. The complete failure that the No Deal outcome represents will blow a massive hole in the political landscape of the UK Parliament and the whole Country. Will the PM take that risk? It’s difficult to tell. But it’s easy to tell that the UK is not prepared for an almighty crash out of the European Union (EU).

This week in aviation we have a reminder of the power and strength of European cooperation. After a farewell tour, the Tornado aircraft is set to retire from Royal Air Force (RAF)[1] at the end of March. The aircraft was built as part of a consortium between the UK (BAE Systems), Germany (MBB) and Italy (Aeritalia). The Panavia Tornado was designed and produced by the industries of 3 European Countries, in one of the biggest, most challenging and successful multi-national aircraft programmes ever run.

It’s part of my history too. I remember working on cockpit equipment for the Tornado ECR (Electronic Combat and Reconnaissance) aircraft. That was in the 1980s. It was my first experience of working on a multi-national programme. Equipment designed in the UK was produced in Germany as part of the close working arrangement between two companies[2][3]. Today, both of those companies are American owned but continue to operate at the same sites.

There is no doubt that we are stronger together in Europe when we work together. Brexit is a devastating blow to the successful history of European cooperation. It’s no-good saying that this is not an issue for the EU. That is to totally ignore the reality of the closer ties that are being forged in the EU. The European Defence Agency (EDA)[4] supports its Member States in improving their defence capabilities through European cooperation. That will grow in strength.
