Bellefonte was a frequent stop in the transcontinental airmail route.

At that time the airfield began pioneering airmail routes throughout Tennessee and the surrounding states.

He was known for flying what was at the time the world's longest airmail route- Miami, Florida to Santiago, Chile.

This aircraft was later used as a pathfinder for French airmail routes to South America.

In the 1920s and 1930s, when many countries issued airmail stamps to publicise their new airmail routes, a new branch of stamp collecting started.

Ford Air Transport Service was started in 1925 to carry passengers and mail on the lucrative new airmail routes.

He flew some pioneering airmail routes throughout New Zealand.

The flight was to be a part of the Air Mail Week observance and an experiment to determine the need for an airmail route through the section.

Because of a high turnover-rate policy in the War Department, most pilots were Reserve officers unfamiliar with the civilian airmail routes.

The DH-4 continued in Post Office service until 1927, when the last airmail routes were passed to private contractors.
