FS2004 Boeing 221A Monomail. The 221A Monomail was a major advance in aircraft design, being one of the first all metal, stressed skin monoplanes built. Despite its advances the 221A's layout harked back to the biplane era, with the cabin forward and open cockpit aft. Lack of a constant speed propeller prevented the Monomail's true success, as better twins were introduced by the time C-S props appeared. Only one 221A saw brief service between Chicago-Cheyenne. This model has full animations, with opening doors/hatches, bare metal finish, VC and some custom gauges. By Tim Conrad.
