I agree that it may be a mistake/typo.  Think of the swath/width of a stereoscopic aerial from a plane flying at 25 feet…

Aerials snapped from "reconnaissance planes flying at 25 feet [my emphasis]." Surely that's a typo or a mistake.

All,



From "The Guns at Last Light: The War in the Western Europe 1944-1945" by Rick Atkinson.



"Armed guards from 10 cartography depots escorted 3,000 tons of maps for D-Day alone, the first of 210,000,000 maps that would be distributed in Europe, most of them printed in 5 colors.  Also into the holds [of the invasion fleet] went 280,000 hydrographic charts, town plats for the likes of Cherbourg and Saint-Lo, many of the 1,000,000 aerial photos of German defenses snapped from reconnaissance planes flying at 25 feet."



Happy New Year to all!
