Also I believe the further away you are from the rotation axis of the plane where it turns left or right, the more unpleasant your flight may be
They appear to make more sense for large passenger jets because the interior volume scales better. There’s a ton of practical concerns though.
They won’t fit into existing airport setups. Seats near the wing will move waaay more than near the center during banking turns (maybe they’ll be cheaper lol)
I don’t think it’s a given they’ll replace what we’ve got, but who knows.
And another company working in the same space, Natilus, is planning to fit 150-250 passengers on theirs, somewhat comparable capacity-wise to a 757, but about 30% smaller length/width.
