with the CW-6, which flew in 1928, and the DC-6, which flew in 1929. He then collaborated with his son, Eldon, in designing and flying the CR-series racing aircraft. Despite the success of new models, the Great Depression led to a catastrophic decline in aircraft sales, a bankruptcy filing for the corporation, and the complete closure of the company in 1931. In 1934, Cessna reopened his Wichita plant, which he soon sold to his nephews—aeronautical engineer Dwane Wallace and his brother, attorney Dwight Wallace—in 1936. After turning over the Cessna Aircraft Corporation to his nephews, Dwane and Dwight Wallace, Cessna returned to a life of farming. Clyde operated an early diesel three-track tractor building ponds for local farmers. Upon Dwane's request, he agreed to participate in the company but served mostly in a ceremonial capacity and stayed out of the company's day-to-day business. Death and legacy Cessna died on November 20, 1954, at the age of 74 in Wichita, Kansas. The cause of his death is unknown. He was posthumously inducted into the National Aviation Hall of Fame in 1978 and the International Air & Space Hall of Fame in 1983. He was ranked number 27 on Flying magazine's list of the 51 Heroes of Aviation in 2013. The Kingman Airport – Clyde Cessna Field in Kingman, Kansas is named in his honor.
