Hiram H. Rowe joined the Air Mail Service on May 25, 1920, assigned to the College Park, Maryland airmail field. On June 10, 1920, he was transferred to the field at Chicago, where he remained for three months. On September 8, 1920, Rowe signed on at the Omaha, Nebraska field in the Western Division. While he was there, he made a couple of speed records during his service, including one in November 1920 when he broke the record between Omaha and Chicago, making the flight of 440 miles in 3 hours and 12 minutes (a record later broken by pilot William Hopson).
On February 9, 1921, Rowe, William M. Carroll and mechanic R.B. Hill were flying their JL-6 airplane when it caught fire in the air and exploded in a nose-dive landing at Lacrosse, Wisconsin. All three men were killed before help could reach them.
