This image showcases a series of world map projections depicting World Air Routes as of December 1957, extracted from The Times Atlas of the World by John Bartholomew & Son Ltd.  It employs a "Nordic" projection for the main map, with supplementary projections for the North Polar Basin, North Pacific Ocean, and Antipodes.

The primary map illustrates global air routes connecting major cities across continents, marked with red lines, highlighting the increasing integration of air travel networks during the mid-20th century. The Nordic projection centers the Northern Hemisphere, emphasizing polar routes that shortened transcontinental travel times, particularly between North America, Europe, and Asia. Notable routes cross the Arctic Circle, reflecting advancements in aviation technology and the strategic importance of polar airways during this era.

  •  North Polar Basin (Gnomonic Projection): This inset provides a close-up of air routes over the Arctic, showcasing the shortest paths (great-circle routes) between major global cities like New York, London, and Moscow, which became more prominent during the Cold War for both commercial and strategic purposes.
  • North Pacific Ocean (Nordic Projection): This view details air routes spanning the Pacific Ocean, linking North America, Asia, and Australia. Key routes connecting Tokyo, Honolulu, San Francisco, and Sydney are evident.
  • The Antipodes (Zenithal Projection): The Antipodes inset  highlights southern hemisphere air routes, particularly those connecting South America, Africa, Australia, and Southeast Asia.

 This map reflects the rapid expansion of global air travel in the post-World War II period, supported by innovations in aviation such as pressurized cabins, jet engines, and advancements in navigation. Airlines leveraged polar and transoceanic routes to optimize efficiency, as seen in the dense web of intercontinental flights.
