A 3- and 5-seater? The real question is which will be more expensive: a eVTOL (vertical take off and landing) ride in one of these things, or a supersonic flight?

There's a lot of things that are unclear here.. why is 3 seat Business and 5 Commercial? How does it Vertically Takes-off with only horizontal engines, no jet vectoring or the like? Moreover the article mentions that liquid hydrogen needs to always be at -250C°, which is wrong.
To sum it up, we have a lot of cool renders and little more.

Yes, but also no!
Nice startup but according to the article, way to ambitious timeline!

Yeah, that forced creativity where all the cool creative names I can think of are already taken

What is “hydrogen-electric”? Or is that just a convenient way to call a liquid hydrogen fuelled vehicle an “eVTOL” so you don’t need a new tag on your blog-news site lol

So the marketing material has arrays of electric ducted fan engines and a ton of batteries next to a hydrogen tank. I couldn’t find how the hydrogen is being used to charge the batteries.

Hydrogen fuel cell is a thing and can use hydrogen to directly generate electricity with up to 60% efficiency.
Hydrogen energy density seems good on paper, but the storage and fuel cell systems add a lot of weight. That’s why all the other electric flight companies are using batteries, they simply perform better.
