Boeing just patented the unusual cargo plane to transfer containers!
The new Boeing cargo plane, instead of storing the containers in its body, it will take them under it.
The peculiar aircraft will be powered by four turboprop engines mounted on top of the wings.
The plane will lower by its landing gear, to store the containers.
The containers doesn’t have to be pressurized, because the plane will fly at the level of 18,000 feet.

There is a patented alternative that has much lower cost to build and operate better structure to load ratio, better aspect ratio, with better growth potential. Presented at professional AIAA conference with no “issue” found. The paper, animation, patent are at ConcordLift.com Much more information is available. There are apparent problems that have non apparent solutions. The patent is available for lease or sale. This Boeing concept has major engineering issues that are addressed by the unusual features of the ConcordLift concept.
The altitude that the airplane I invented flies at depends on the cargo being transported.
