Commander Ronne flew 39,000 miles of mapping flights through air so pure that a pilot could see 200 miles ahead. His special trimetrogon cameras (three cameras working simultaneously) could snap horizon-to-horizon photographs every 20 seconds for the mapmakers. The photos would make it possible to chart the last unknown coastline in the world. With the explorer's prerogative, he named places for friends and colleagues: Edith Ronne Land for his wife, Isaiah Bowman Coast (for the geographer-president of Johns Hopkins), Lowell Thomas Mountains, Larry Gould Bay (for the explorer-president of Carleton College...

...most important new invention is "trimetrogon" photography. This enables a flyer to photograph the ground below from horizon to horizon. The equipment consists of three cameras with wide-angle lenses, one pointing straight down and one obliquely to each side. By means of triangulation and ingenious translating devices, distortions resulting from the oblique angles are corrected in the final print. The trimetrogon method, by making it possible to space charting flights 25 miles apart instead of only four to six, has enormously accelerated mapping. Last fortnight its inventor, Lieut. Colonel Gerald ("Colonel Fitz") Fitzgerald, Chief of the Air Force...
