On display in the Time and Navigation exhibition at the National Air and Space Museum. This specially modified 5C Vega set the record in 1931 for a flight around the world, taking 8 days in the hands of Wiley H. Post and Harold Gatty. Post repeated the feat solo, taking only 7 days in July 1933. In March 1935, Post flew this Vega high enough from Burbank to Cleveland to be operating in the jetstream. The Smithsonian acquired 'Winnie Mae' shortly after Post's death in a flying accident in August 1935.
