Augustus Moore Herring prepares to launch himself in Octave Chanute's 1896 biplane glider. The lower wing is supported by an unidentified man, and the proceedings are observed by Octave Chanute's dogs Rags and Tatters. Indiana Dunes, 1897.
Note the biplane wing layout, vertical struts, and bracing wires. As with Lilienthal's glider, the pilot controlled the craft by shifting his body weight.
