This has the basic lay-out of an airplane, but with ascension-oriented propellers on the wings.
- Inventor locations: Alexis Beurrier was located within département Charente-Inférieure, now département Charente-Maritime, France, Edmond Bigourdan was located within département Seine-et-Oise and Louis Lacoin was located within département Seine.
We are leaning to the overwhelming likelihood that this Edmond Bigourdan is in fact Édouard-Jean Bigourdan.
