"Aeros' were aircraft that were designed, built and flown
by members of the Sonora Aero Club in California during the years 1850 to 1858.
These aircraft were navigable airships, built at a time when the only means of flight was the aerial balloon, which lacked maneuverability and was subject to the whims of the wind. A member of the club, Prussian born American artist C.A.A. Dellschau, kept a secret record of all their activities and experiments. According to Dellschau these aircraft may have flown as far as the giant redwoods
area of California where one of their airships became accidentally entangled in the branches of a giant California redwood, resulting in the death of its pilot, who fell from the Aero and broke his neck.
It all sounds rather fantastical and perhaps it is. Exhaustive research has found nothing to substantiate the existence of the Sonora Aero Club except for a few gravestones in the Columbia Cemetery where several of the surnames are found. However UFO writer Pete Navarro suggests that a coded story is hidden throughout the drawings, which he interprets to mean that the Sonora Aero Club was a branch of a larger secret society known only as NYMZA.
