What really is needed is a shot of that old-time engineering nerve. Ironically, says Paul Czysz, a professor emeritus of aeronautics at St. Louis University, that might have been found in the McDonnell Douglas archives. During the 1980s and 1990s, engineers there developed what is called the "blended wing"—a variation on the flying-wing model used in the B-2 bomber. Basically, a blended wing is simply a fat wing with the engines and tail fins attached to it—no long skinny tube with the wings stuck on the side. It's an ideal design for commercial aircraft—even more fuel efficient than the proposed 7E7, capable of carrying huge loads, easily switched between passengers and cargo and back.
yeah.. this guy has it figured out all right
