Although today's aircraft are for more complex that their WWII counterparts, these were still at the apex of high technology and necessitated detailed instructions on maintenance and other forms of instruction for the specialized fitters, mechanics, and other service personnel. For example, this B-17 manual detailed the correct tools and procedures for servicing this aircraft. Other air forces produced similiar manuals, like this one for the Japanese Ki-43 or these various handbooks for the Bf 109.

Obviously the pressures of wartime sometimes meant that certain procedures could be circumvented or skipped, but as a whole the maintenance regimen was pretty well established. The expansion of the air forces meant that a large number of men had to be trained quickly, which led to various creative multimedia approaches to training. The US would often have cinema films for training, such as this B-29 instructional video narrated by Ronald Reagan for the flight engineers. One other means of education was comedic posters, such as the U. S. Navy's comic Dilbert (from which Scott Adams named his famous character after) whose posters emphasized a proper safety regime for pilots and even featured in a gunnery safety video with the excellent title Don't Kill Your Friends. Nor was such comedic education limited to aircraft, one of the German manuals for the Tiger tank, the Tigerfibel, visualized the tank as a sexy blonde named Elvira who needs proper oiling and other maintenance to keep at optimal performance.
