This has been talked about a long time, replacing the windows with screens. I don’t see how it will make faster or fly higher enough to make a difference to the passenger. There would be some fuel savings. The screens could show what is outside the plane. For some I thought what would I do if I could hack these screens? Same show came to mind. But I wonder if they notice it was B/w picture? While passengers think they landing Hawaii show them landing in a Baltimore winter.
Why do planes have two engines? To get you to the crash site when the first one fails!!
