Although this does not relate to aircraft it is applicable to some of the postings on this thread.
Many years ago I was techrep on the Atlas Ballistic Missile. When the launch pads were about to be turned over to the Air Force the Tech Manuals had to be validated.
In the process of doing this, we found that what was in the manuals in no way resembled what was on the launch pad. Also, none of the equipment worked the way is was supposedly designed to do. We brought these problems up to our Air Force superiors and we made a recommendation. The Air Force followed our recommendation and the engineers and tech writers were directed to report to Vandenberg AFB and under our direction they were made to work on the equipment that they had either designed or wrote about in the manuals. This went on for a month and the writers and engineers returned to San Diego and it took several months to get things sorted out.
