In 1930, the record for flying around the world was not held by a fixed-wing aircraft, but by the Graf Zeppelin, piloted by Hugo Eckener in 1929 with a time of 21 days. On June 23, 1931, Post and the Australian navigator Harold Gatty, left Roosevelt Field on Long Island, New York, in the Winnie Mae with a flight plan that would take them around the world, stopping at Harbour Grace, Flintshire, Hanover twice, Berlin, Moscow, Novosibirsk, Irkutsk, Blagoveshchensk, Khabarovsk, Nome, where his propeller had to be repaired, Fairbanks where the propeller was replaced, Edmonton, and Cleveland before returning to Roosevelt Field.
