"Measures of Relative Air Traffic Generating Power... Population... White Only"

Important map of the world on a gnomonic (great circle) projection, showing great circle routes between the major air hubs of the 1930s. The map includes three other gnomonic charts, one a South Polar-projection, a chart of the South Atlantic, and another of the South Pacific.

Fascinating and indispensable map for understanding the early history of global aviation. The present map would have been prepared in small numbers for a few public and private American policymakers. 

One noteworthy feature of the map is that, in the legend at the right, it differentiates between the policy impacts of the airlines on "Population... Total" and "Population... Whites Only".

The legend differentiates the following routes: Present American Flag Routes; Present Other Flag Routes; Projected Commercial Routes; Alternative Commercial Routes; Projected Policy Routes. The length of each leg is noted on the map.

At lower left is a table of distances, comparing steamship and airline transit distances and times between various major world cities.

Date estimated based on world population (given as 2,152,411,000).


Lloyd Welch Pogue (October 21, 1899 – May 10, 2003) American aviation lawyer and chairman of the Civil Aeronautics Board. Pogue, a native of Grant, Iowa, was instrumental in forming the policy structure that led civil aviation through World War II and into the booming Post-War Period. He was appointed Chairman of the CAB by President Franklin Delano Roosevelt, and he served as Chairman until 1946. During his tenure Pogue helped strike down a plan for a single world airline.
