The Allplane Podcast

Among the top contenders in the eVTOL space, EVE Air Mobility stands out—not because it's closer than others to entering service or because it generates more media headlines.In fact, what sets EVE aside from the pack is the backing of one of the world’s most successful and technologically advanced aircraft makers, Embraer, which has opted to move slowly but steadily in the field of advanced air mobility.And leading EVE Air Mobility on the commercial front is our guest in this episode of the podcast, Megha Bhatia, the company’s Chief Commercial Officer.In this conversation with Megha we cover the latest developments at EVE, including the firm’s participation at the 2025 Paris Air Show, where it showcased a full-scale mock up of its eVTOL aircraft, as well as its commercial traction and future prospects.We also cover in-depth the 20-year global market outlook report which EVE published earlier this year and discuss what is the role EVE Air Mobility wants to play in the highly competitive advanced air mobility market and its unique selling points.So, if you are interested in what’s going on in the nascent eVTOL industry and wish to learn more about one of its most promising projects, tune in for this fascinating conversation with Megha Bhatia, Chief Commercial Officer of EVE Air Mobility!

The world badly needs sustainable aviation fuel (SAF) and, fortunately, there is not shortage of entrepreneurs willing to take on the challenge to scale up production. Now, are all SAF pathways the same? Of course not.Today on the podcast we will talk with Mukund Karanjikar, founder and CEO of CleanJoule, a SAF startup based in Utah that is developing a SAF production method that delivers more joules of energy per unit of fuel mass than other traditional biogenic pathways.What’s more, not content with powering a commercial aviation industry that is thirsty for SAF, CleanJoule is also developing biogenic SAF for space travel. So, when it comes to CleanJoule, you could well say that the sky is not the limit!The prospect of clean space travel is quite interesting by itself, but, of course, there are other considerations too, such as cost and strategic independence and, on these two counts, CleanJoule is also ready to deliver, says Mukund.So, in today’s episode we are going to learn a bit more about CycloSAF and CycloRP, the two flavours of sustainable aviation fuel that CleanJoule is developing (for the aviation and space industries, respectively) and how CleanJoule plans to roll out and scale production before the end of this decade.We will also talk about the positioning of CleanJoule is the broader and constantly evolving SAF industry landscape and why this startup has got the attention of prominent investors such as Indigo Partners (a private equity firm which owns a global portfolio of low-cost airlines) and Temasek (one of Singapore’s most prominent groups).So, tune in for a fascinating talk with Mukund Karanjikar of CleanJoule about one of the most promising technologies I have seen so far in the field of SAF!

In this episode of the we welcome Shashank Nigam, who, together with Dirk Singer, has co-authored the Sustainability in the Air book series, two volumes that cover many of the most prominent entrepreneurs, companies and projects striving to make air travel cleaner and more sustainable.Now, Shashank is no newcomer to the aviation industry. He is also the founder of Simpliflying, a firm that has been providing advice in marketing and sustainability to airlines and airports for quite a few years, and also runs the Sustainability in the Air podcast.So, in a way, this is a bit of a special episode because you get not just one, but two sustainable aviation podcasters on the show!With Shashank we talk about the second volume of Sustainability in the Air and what’s new in this new book, which focuses on how the industry is moving from experimentation towards execution and how the different players in the ecosystem are learning to collaborate. Global sentiment towards sustainable aviation has swung a bit with the volatile global political and financial situation, but, as Shashank says, sustainability is a marathon rather than a sprint! We even had some birds singning in the background during the recording, quite apt for a podcast about sustainable air travel!

In this episode of the podcast we’ll explore one of the most truly disruptive clean-sheet aircraft projects currently underway.Scott Drennan is President and Chief Operations Officer (COO) of Otto Aviation, a US startup aircraft maker that is developing an ultra-efficient executive jet. The Phantom 3500 uses a teardrop-shaped design to take full advantage of the laminar flow principle and reduce drag to a minimum.Otto Aviation is, in fact, not a newcomer. The firm has been working on this concept for more than a decade, although in the last few years it has pivoted from the original idea, the Celera 500L propeller aircraft for the general aviation market, to the Phantom 3500, a fully-fledged business jet which aims to compete in the super-mid-size category of business jets.With Scott we talk about Otto Aviation’s disruptive approach to aircraft design, how laminar flow can be mastered to achieve some unprecedented fuel efficiency gains and what this involves in terms of financial and environmental performance. We also touch upon one of the most eye-catching features of the Phantom 3500: the absence of windows for extra aerodynamical gains and how Otto Aviation is responding with a new way to conceive the passenger experience.And, following the announcement, made during the 2025 Paris Air Show, that Otto Aviation is investing in a greenfield manufacturing facility in Jacksonville, Florida, we also discuss the company’s investment plans and go-to-market strategy. How many aircraft is it planning to build per year? Who is it planning to primarily compete with and how?Tune in for a fascinating conversation that combines technical and commercial insights about the unique Phantom 3500 business jet, a flying bullet which may change how we think about aerodynamics and aircraft construction!

When we talk about aviation sustainability, the first thing that usually comes to mind is propulsion technologies or new aircraft designs.But there are other ways to lower the environmental footprint of flying. Some are even hidden in plain sight!Today we bring you the story of a company doing its bit to make aviation more sustainable, but in a rather original way: GenPhoenix makes ELeather, which is an innovative lightweight material that can be found on many aircraft seats.ELeather is actually made by upcycling organic leather scraps, preventing them from going to a landfill (and liberating methane) while, at the same time, helping bring down weight onboard the aircraft, with the related savings in fuel and emissions.Lisa Conway, Chief Revenue Officer at GenPhoenix, has been on the podcast to share all the details about this interesting technology, which you may have already been using, even without noticing!Tune in for a fascinating conversation about this segment of the industry that operates at the crossroads between sustainability and passenger experience!

Ivar Aune is the CEO of SiriNor, a company working on an electric jet engine.Yes, you read that right! While most electric aircraft projects aim to power a propeller, SiriNor is going for the very technology that powers most of today’s commercial aviation industry.After all, a modern jet engine works by making a turbine spin. But while conventional jets rely on a combustion process that produces very high temperatures, SiriNor aims to replace that bit with an electrically-powered mechanism.The result: cheaper, easier to build engines which are as performing as conventional ones.All of this is still some time into the future, since SiriNor is still, by most measures, a young startup. However, Ivar’s team has already tested successfully one of its electric jet engines on the ground and it is aiming to have some certified and commercially-ready models for UAVs and ground-effect-vehicles within the next couple of years.If this sounds ambitious, you haven’t heard it all yet, because the ultimate goal is to be able to apply the electric jet engine technology to larger aircraft, potentially even the A320/B737-sized airliners that are the workhorses of today’s aviation industry. A rather tall order, indeed, but Ivar, who spend the earlier part of his career in the Norwegian oil and gas industry, has no doubts about the need for the aviation industry to make bold bets if it is to remain, over the next decades, the engine of growth that it has been to this day.So tune in for a fascinating conversation about a truly promising, and rather intriguing, technology that has been, pretty much, kept under wraps until very recently!

Wizz Air takes pride in having the lowest carbon footprint per passenger and kilometer in the airline industry, 52g, number that it expects to bring further down as it renews the fleet with larger, denser and more efficient aircraft.But fleet renewal alone won’t do the trick. In fact, “fleet” is just one of the three “Fs” that the pan-European ultra-low-cost airline relies on to get to Net Zero by 2050, even in a context of growing air traffic.“Footprint”, that is, efficiency improvements in the way aircraft are operates, is another, relatively minor “F” in this vision. But the bulk of the carbon reduction will rest upon the massive use of sustainable aviation fuel (SAF).Since production of SAF is currently small, Wizz Air has decided to take a proactive stance and become a direct investor in a number of innovative SAF projects, one of the most promising of which is Firefly, a British startup that turns sewage into SAF.In this episode of the podcast, Yvonne Moynihan, head of ESG and sustainability at Wizz Air, and James Hygate OBE, founder and CEO of Firefly, share the (virtual) stage to explain this project in detail. We will talk about how Firefly technology works, how scalable it is and how does this project fit into Wizz Air’s SAF-sourcing ans well as in the airline’s broader decarbonization plans. Tune in for a fascinating chat about one of the most interesting SAF projects right now in Europe and how it will help Wizz Air strengthen its sustainability credentials even further…

In this episode of the podcast we welcome Amelia DeLuca, Chief Sustainability Officer at Delta Air Lines.Besides being one of the World’s largest airlines, Delta, is also a very active player in the field of air travel innovation and decarbonization.Delta has committed to getting to net zero by 2050 with Sustainable Aviation Fuel (SAF) expected to play a big role in achieving this goal. To this end, Delta has signed a string of SAF deals across the US and is also working with SAF producers in several states to increase supply of this so-far scarce type of fuel. Delta intends to use 10% of SAF in its fuel mix by 2030 and to increase this figure to 35% by 2035. But this is not the only path to decarbonization that Delta is exploring. In fact, when it comes to sustainability, Delta is active on so many fronts that it has created the Delta Sustainable Skies Lab to gather all its sustainability-focused initiatives under one roof. Remarkably, just as Delta is marking its centenary, it is also actively investing in technologies that promise to re-shape the way to travel in the next 100 years. Two examples of this policy are Delta’s is investment in leading eVTOL developer Joby Aviation and its strategic partnership with JetZero, a startup developing a revolutionary blended-wing-body aircraft concept capable of halving fuel consumption, all while redefining completely the passenger experience.So, tune in to listen to Amelia talking about all these exciting projects and explaining how they fit into Delta’s vision of the future of commercial aviation!

Flynow is an Austrian eVTOL developer with big ambitions and, so far, a low media profile. But you can be sure that if you ever come across one of its eCopters, with its distinctive capsule-like, tail-less shape, it will catch your eye!Yvonne Winter, our guest in this episode of the podcast, is the co-founder and CCO of this startup, which aims to produce tens of thousands of electrically-powered eCopter eVTOLs, both for cargo and passenger transportation. The idea is that the eCopters will be automated fly so that costs go down to the point when eCopters become competitive with land transport.Despite being based at the foot of the Alps, it may be the Saudi deserts that may first see the eCopters in action, though, since Flynow is working with a local partner to produce and test these small aircraft in the Middle Eastern Kingdom.In our conversation, Yvonne enumerate the advantages of the approach Flynow has chosen and why she is confident the eCopter will soon be operating commercial missions, in Saudi Arabia first and then elsewhere. So, tune in for an interesting conversation about the no nonsense way to design an eVTOL: leveraging proven technologies, set for itself achievable goals and made small steps towards their fulfillment!

This episode has two exceptional guests because more often than not, innovation doesn’t happen in isolation. Great successful products and services are those that fast achieve product-market fit and this is precisely what we are going to talk about here today.Our guests are Marc Allen, CEO of Electra, a US startup that is developing a hybrid-electric ultra-short take-off and landing aircraft capable of landing in incredibly short open spaces, and Tomislav Land, co-founder and CEO of Flyvbird, a startup airline based in Germany which aims to transform regional air travel with an on-demand capilar air mobility network.At this point, I must say that Tomislav is, actually, a veteran of this podcast, since he was here already in 2022 when Flyvbird was starting to take shape.Quite a few things have happened since then, so we do examine with Marc and Tomislav the current state of the industry, and talk about what the market is asking for right now.And while it is true that the market has cooled somehow when it comes to some of the most complex cleansheet aircraft projects from the point of view of technology, regulatory burdens and capital requirements, there is still plenty of appetite for advanced air mobility projects that are low risk, clean, safe and efficient.And Electra’s EL9 aircraft, which is currently undergoing development and evaluation, among others, by the US military, seems to tick pretty much all these boxes. Marc will provide us with some insights about the current status of the project and the steps it is taking towards certification, while Tomislav will explain how it fits perfectly in Flyvbird’s plans to build a new generation on-demand regional airline. Last but not least, both CEOs also talk about the ways they are collaborating to ensure success through the so much sough-after product-market fit.Tune in to learn more about one of the most non-nonsense cleansheet aircraft projects right now in the market!

Vertical Aerospace is one of the world’s leading advanced air mobility developers, at least when it comes to its order book.Some 1,500 units of its VX4 eVTOL aircraft have already been pre-ordered (including a 500 aircraft order from Avolon, which the lessor then managed to place in a matter of months with a handful of airlines), but before that, Vertical Aerospace will have to complete a thorough a comprehensive testing and certification process.And no one better placed to talk precisely about this than our guest on this episode: Michael Cervenka, Chief Technology Officer at Vertical Aerospace.Michael is an industry veteran, who, prior to joining Vertical Aerospace, worked for quite a few years at that other flagship of British aerospace industry, Rolls-Royce. We recorded this conversation as Vertical Aerospace was preparing for a key step in its development process: its first piloted untethered flight. So, we talked with Michael in full detail about this ongoing testing programme, its current status and the challenges that lie ahead.And, then, of course, we discussed in detail other aspects of Vertical Aerospace’s plans , such as its value proposition, its industrial plan, which, unlike other eVTOL developers, involves a whole ecosystem of partners working together. There was also time to discuss financial and commercial aspects of the project and even some little known aspects of the project, such as the main differences between an eVTOL and a helicopter or why prototypes are painted white.So, tune in for an in-depth conversation about one of the most fascinating eVTOL projects in the world right now!
