I've been reading this thread with interest. You'll tell me if I'm wrong, JvH, but I believe the situation is that the HUD code (i) contains information which is proprietary ("industrial property") and (ii) attracts an [inter]national security protective marking, i.e. in loose journalistic terms it's a military secret. I can see several reasons why the latter should be the case if the HUD code tells you about the capabilities and performance of an in-service military aircraft. What this implies is that the HUD code is very specific to a particular aircraft, and hasn't been written so that the SECRET bits are parameterised. Yesterday, you wrote '... we can't distribute ... even the symbol definitions' which I find intriguing; when I last had access to information in this area, the symbology was the subject of unclassified NATO definitions. Have you got a foo fighter underground somewhere? Seriously, in my experience it is the *performance characteristics* of military equipment that are secrets - if the aircraft is in service there will be an entry for it in Jane's! Is the information which makes the HUD classified so embedded that it can't be extracted?
