Well, since you made your way to Ecomodder to press your case—welcome—and I take back anything bad I might have said.
So... Your airframe seems to be sized for 40ft containers. Can it accommodate two 20ft containers? Another aircraft half the width for those?
What airport will be available for these? Will there be infrastructure to weigh and sort the containers to provide optimized weight distribution and polar moment? Can it accept partial loads? Fly empty?
If your going to cover the bottom with a 40x144ft tarp or something shouldn't that be part of the patent claims? The top and sides of the airframe will have to be stiffened to allow that size a hole in the fuselage. One would think.
