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.

Just gimbal the seats.

But are you willing to pay 10-20% more for that joy? I personally would rather pay less money to fly, not get to see out the window, and spend those dollars on, say, a fancier meal at the destination. Or to have an extra day at the destination if my trip length is money-bound rather than time-bound. Or put those dollars towards an extra hour of childcare. Or … I have so many uses for dollars that give me more utility than “see out the window while flying”.

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.

Only a small fraction of current flyers get window seats. And the view from the isle seat or middle row is non-existent.

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.

Skylights, Or floor windows for the freaky

Also the screen sizes they are showing have got to be exceedingly heavy.

I'm fine with not looking out of the window if the seat is comfortable and I can get to the bathroom more easily. And I'm sure I'm not the only one. Window enjoyers such as yourself will still be able to get the window seats.

Just bring a sleep mask.

No, virtually all the radiation with the exception of UV is passing straight through the airframe. The protection an aircraft body offers is negligible.

I wonder if it makes more sense to just get the latest batch of people doing the military -> civilian transition and starting them off on these

Hell why even travel when you can just see Venice on a screen.

Jeez way to ruin of the few remaining joys of flying. Lock everyone in a tin can. You will experience reality through screens only and you will enjoy it

True - unlike a car, it’s not like one could open a window in a plane.

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