They were in a position where they had to train millions of raw recruits in a short period of time, on unfamiliar equipment. So they wanted to institute consistent controls across all the equipment, because of the rapid turnover of technologies in wartime, and the dozens of different manufacturers of aircraft, tanks and vehicles. Plus, they knew this equipment would be operated under stress (that’s an understatement) and in poor weather and lighting conditions. Pretty much every one of their recommendations is still valid; unfortunately, modern designers trained on onscreen apps feel they can reinvent the wheel at will without considering any of these factors.<div class=""><br class=""></div><div class=""><br class=""><div class="">
