This here is my attempt at making a Boeing 2707-300 jet plane.
This was uneccesarily difficult and time consuming. I spent too long fighting with trying to use curves to make smooth shapes and trying to get the inset windows to work. I now see there's a reason people made plugins like Kit Ops, Box Cutter and other such things on the Blender Market. I'm definitely going to be buying those.
