William D. Lindsley of Waynoka, Oklahoma, invented several everyday items, including fishhooks and flyswatters. In 1909 he began experimenting with aircraft designs. His first design was called the Oklahoma Monoplane; a sketch of which appeared in the Waynoka Democrat newspaper on March 5, 1909. In January 1910, he applied to the Unites States Patent Office for a patent on his flying machine, which was eventually granted on September 5, 1911.
