The Alaparma Baldo was an unusual two-seat light monoplane produced in Italy shortly after World War II. Designed by Adriano Mantelli, it featured an egg-shaped fuselage with cabin doors that hinged upwards and to the back. The conventional tailplane with single fin and rudder was carried on twin booms, either side of a pusher engine installation. The undercarriage consisted of a single mainwheel under the fuselage pod, a small tailwheel not far behind it, and outrigger wheels on the wingtips.
