In those early days of high performance jets, with an industry having only rudimentary knowledge of supersonic aerodynamics, no computers to help design either airframes or engines, and a wing sweepback design copied from a German jet, it was no surprise that the airframe had very troubling flight characteristics (highlighted when NA's chief test pilot George Welch was killed during a high-speed dive, the first of several crashes), and the engine encountered severe compressor stalls caused by inlet duct curvature.
While few discontinuous changes have occurred for technology within the airline industry, there have been some major incremental advances that have been geared toward increased efficiency--new fuselage designs such as sweepback wings, advanced aviation systems, and information systems modifications.
