It was not until many years later that the assertion regarding the Red Baron was disproved. John Hedley's incredible tale was included among the anecdotes in the 1929 book "Luck: Your Silent Partner" by Lothrop Stoddard. In 1930, John Hedley was still living in Chicago, with his wife and two sons. His occupation at that time was reported to be a lawyer. By 1942, the year of the United States World War II draft registration, Hedley resided in Dayton, Ohio. At the time of an interview conducted in 1960, Hedley was living in Hollywood as a retired accountant. John Herbert Hedley died in Los Angeles on 1 April 1977. Despite his death, the former aviator still appears to have an audience. In 2009, the story of Hedley's bizarre mishap in 1918 was included in the book "Strange But True, America: Weird Tales from All 50 States". In addition, John Herbert Hedley and his incredible tale were the subject of the 2011 YouTube video "The Luckiest Man Alive! – Strange as it Seems (2011)".
