Historical Aircraft Monographs and Digests are the technical/historical documentation of a specific aircraft evolution (when adequate details can be found) or a class of aircraft (when they can't). All are in black and white with detailed 5-view drawings, engineering sketches of details that are not obvious in 5-views or photos. Includes cockpit layout perspectives, specs, development history, performance, operational history, color scheme, markings, descriptions and copies of manual pages (when they can be found). No photos or colored artwork. Many of the HADs have companion CDs which have an assortment of photographs (many in color) and drawings.
