Charles Dellschau’s work was in large part a record of the activities of the Sonora Aero Club, of which he was a purported member. Dellschau’s writings describe the club as a secret group of flight enthusiasts who met in Sonora, California in the mid-19th century. One of the members had discovered the formula for an anti-gravity fuel he called “NB Gas.” Their mission was to design and build the first navigable aircraft using the NB Gas for lift and propulsion. Dellschau called these flying machines “Aeros.” Dellschau did not claim to be a pilot of any of the airships; he identified himself only as a draftsman for the Sonora Aero Club. His collages incorporate newspaper clippings (called “press blooms”) of then-current news articles about aeronautical advances and disasters. According to a coded story hidden throughout the drawings in his notebooks, the Sonora Aero Club was a branch of a larger secret society known only as NYMZA. Despite exhaustive research, including searches of census records, voting rosters, and death records, nothing has been found to substantiate the existence of this group except for a few gravestones in the Columbia Cemetery where several of the surnames are found. It is speculated that, like Henry Darger’s “Realms of the Unreal”, the Sonora Aero Club is a fictional creation of Dellschau’s.
