Re: Flying wings/bodies
A real problem with flying wings as passenger aircraft is that people sitting some distance from the central access will experience relatively large vertical accelerations and decelerations as the plane banks. Apparently those sorts of motion are linked to serious barfage - so I'm guessing we'll see them round about 'never' - unless the airlines take the next step in making air travel more 'efficient' by anaesthetising people at check-in and stacking them like cordwood.
