- The title is difficult to interpret and translate. Possibly (from DeepL): "Longitudinally-developed airplane with reversible gear and stable balance in a possible vertical drop-stabilized and maneuvered while in motion by rotation of load-bearing surfaces and directional rudders-obtained by hydraulic impulse determined and adjusted automatically and by hand". Or "Longitudinally extensive airplane, with reversible direction and stable equilibrium, in one possibility stabilized vertically and maneuvered in flight by means of sustaining surfaces directed by a helm — given a fixed hydraulic impulse and regulated automatically and by hand"
- Inventors' location: Perugia (From en.wp: Perugia is the capital city of Umbria. It is north of Rome and southeast of Florence.)
