The Monomail wing was set lower, was smooth, made entirely of metal and had no struts (cantilevered construction). The retractable landing gear, the streamlined fuselage and the engine covered by an antidrag cowling added up to an advanced, extremely aerodynamic design. The 221A was a revised version designed for transcontinental passenger service.BI223983 (4820b)Maximum size:7345px × 5876px (~123 MB)24.4in × 19.5in (300dpi)License type:Rights ManagedKeywords:1930s-airplanes-Boeing Field-Boeing livery-buildings-commercial-commercial passenger planes-copy space-day-exteriors-full body views-gray skies-grid patterns-ground shots-hangars-historic production status-left rear views-left side views-Monomail-Monomail Model 221A-monoplanes-photos-propeller planes-silver color-tarmac-text-unpainted-vintage / retroRelated Photo/Videos:View AllRelated Virtual folders:Monomail 221
