Today, Airbus has been granted a patent (US 9,193,460) on a method that essentially turns an airplane into an articulated truck. The plane, instead of being a single, contiguous hull, would have a huge hole in the middle where the passengers and luggage would normally be. Instead of boarding the plane directly, passengers and luggage would be loaded into a separate "cabin module." Then, when the module is ready to go, it's simply dropped into the airplane. If you ever watched Thunderbirds as a kid, it's a lot like Thunderbird 2.
