>Why isn't this design used commercially? In a commercial plane, passengers will rise/drop during turns relative to the center line, but it's minimal due to distance from center line. The further out passengers are from the center line, the more they will drop/rise during turns. Imagine being seated towards the outer edge of this fuselage. You might rise/drop 20-30ft off the centerline during a turn.
