Schematic  bomber 1940850

This is a not-frequently-seen schematic of the Royal Air Force’s Sunderland, a flying boat, and the largest airplane in British service, pictured and slightly dissected in Popular Mechanics in 1940.  (Apologies for the blurry definition on the left side–the book is huge, and not very friendly to the scanner.)
