The Crew at Yakima Aerosport put an interesting idea in my head: patroller doors.

I thought this was extraordinary. Why settle for an opaque door when you can essentially have a window that goes from the wing to the floorboard? This gives the back seat riders a reason to want to sit in the back and it makes the rear cabin much less “claustrophobic”.

UPDATE! This is what the doors look like on the finished plane.
