JetZero

For an all-wing design to work the onboard flight control system needs to make thousands of microscopic surface adjustments every second to keep the flight stable. This is much more practical with today's computing power and technology, even if the concept may have been thought of long ago.

Mentour Now! has a great video discussing the aerodynamics of the B-2 which has a lot of relevancy to the JetZero design. https://www.youtube.com/watch?v=BLtzjP1_3nQ

No windows

Evacuation issues

Won't work in some airports

Nausea inducing

... It's not without issues.

This sounds fixable in avionics and training. (Shallow, gradual banks.)

Note, too, that a larger lifting body needs to bank less to execute the same turn as a craft with more loading.

And that's before we talk about night flights when there's nothing to see, flights over water when there's nothing to see and so on.

So yes, I'm sure some people like windows. But the majority have demonstrated that they're just fine flying without them.

Where that number comes from: they claim 50% reduction in fuel consumption, which sounds doubtful to me, and fuel is about a third of flight costs, and I’m making some generous assumptions around perfect competition.

Interior isle seats cost as much as window seats in airlines that charge for position. People just want space.

Just hope they don’t make an “ad-free” window a premium upgrade…

So far, I see zero evidence that this company has addressed any of the aforementioned challenges beyond theoretical fuel consumption and theoretical passenger logistics.

As someone who has 31 hours towards their single-engine ppl cert, I absolutely abhor the stagnation of general and commercial aviation due, largely, to certification barriers, BUT even having a viable flight-worthy blended-wing concept does not make for a viable mass market product.

Not related, see the near half-century of "alternative" wing and airframe designs that are absolutely better at a few pieces of the puzzle, but also absolutely failed to be viable when integrated into a fully functional and safe airplane.

This company needs to focus on success in a niche product role before addressing the safety, integration, and manufacturing needs of the mass commercial aviation market. They are not (atm) backed by this sort of "patient capital".

Not related, see all of the VC and failures required by Whittle (in wartime no less) to develop the jet engine or Tesla's corporate journey from Roadster -> S -> Y.

traditional looking commercial jets, their designs, their manufacturing processes, their innovations (yes boeing/airbus do innovate and have for a long time even though it doesnt seem that way) have all been shaped heavily by human blood. to some degree a radical new design almost guarantees more deaths at a commercial level there's really no shortcutting this without it.

dont get me wrong im super open to the possibility that something like this is possible itd be better for the whole world, but there's no way we get there without re-experiencing some hard lessons if we want to push it pash some sort of proverbial finish line

Just because some people go to work in inefficient and dangerous-to-others cars does not make them more efficient. I am working a construction job, does this mean I should not think about what I am doing ?

To your argument of (paraphrase here) 'it is good enough why innovate'. I flat out reject that argument. Horse and buggy were good enough. The telegraph was good enough. We only needed 1 mb of memory because it was good enough. We are missing so much right now. We potentially could have small, efficient, point to point air taxi service for the average person, completely dismantling the massive, and horrible to deal with for people, hub and spoke system. Travel could get so much better and cheaper, but instead we have the 737 max. An incremental change on a decades old design because real innovation is lacking in the industry.

I also feel like a lot of modern air travel is designed around making something that's highly unnatural and inherently terrifying into something palatable for most people. I'm not talking about actual safety, but the perception of safety. Which isn't exactly a logic thing. More about keeping that lizard brain from freaking out too hard.
