…been successfully applied to several high-subsonic aircraft, noticeably increasing their fuel efficiency. Early examples include the Boeing 757 and Boeing 767 airliners, both of which were developed during the 1970s. According to Hirschel, Prem and Madelung, the supercritical wing has been regarded as being…
