On March 15, 1935, Post flew from Burbank, California, to Cleveland, Ohio, a distance of 2,035 miles, in 7 hours, 19 minutes. At times, the Winnie Mae attained a ground speed of 340 mph, indicating that the airplane was indeed operating in the jet stream. He reached an unofficial altitude of more than 50,000 feet.
