Dellschau drew the 'Sonora Aero Club' airships; the notebooks were found in a junk shop and decoded as 'NYMZA' by Navarro

Documented · occurred What these labels mean →

Charles Dellschau (1830-1923) drew airships attributed to a 'Sonora Aero Club.' After his death the notebooks went to the Washington Street dump in Houston, were bought by junk dealer Fred Washington, and Dominique de Menil bought four of them in 1969; in 1972 Pete Navarro bought one for $65 and then the remaining seven, and he reads the code 'DM=X' as 'NYMZA', a secret society. The club's story comes from Dellschau's own notebooks; whether it was real is unresolved.
