Ah yes - the documentation provided...
If I remember for the entry of the E-3D into service....the US equivalent of the aircrew manuals arrived at Waddington some time after the aircraft and we (the aircrew) were asked to make observations. Sadly, all of the diagrams referred to an E-3C - there was not a picture that contained an E-3D with a refuelling probe and the engines were Pratt and Witneys and certainly not CFM-56s. We shortly realised that we would have to write our own manuals based upon the existing USAF manuals. Unfortunately, the classified documents did not arrive until a year later and were blatantly WRONG in several areas! The difficulty in correcting these documents was that we had no facilities for changing these documents and they went on for many years uncorrected - unfortunately, when teaching subjects such as radar, the students were often confused because their instructor (me) was telling them something different to the manuals (if they actually bothered to get them out).
