Strewn along the flight path they first found a wing section, then the nose, the rest of the wings and the aircraft's tail and engines.

Even within the 'Left Wing Section' itself democratic methods are not used.

This increase in efficiency was due to careful attention to detail in every part, improved wing sections, clean fuselage-lines, and simplified undercarriages.
