There seems to have been something peculiar to the Javelin that attracted larger than life stories. The classic FEAF one was of the one that supposedly was scrambled to intercept an Indonesian C130 incursion of Malaysian Airspace during Confrontation, and reportedly returned to Tengah minus a Firestreak missile.

Not casting any doubt on your stories, Danny, though I see you do that somewhat for yourself. Your Cold War tale of the testing of the ADIZ that bordered East Germany reminds me of one that occurred over West Berlin. Evidently the Control Zone was thrown into confusion by the entry into it from the East of an unidentified aircraft with which no radio contact could be made. It plodded on well into the Western Sector until, as though tired of the game, it turned East and plodded out again. Telephone lines buzzed, the Russian staff at the ASC were as confused as everyone else, but they finally received an explanation from their superiors and passed it on in turn to their Western counterparts. It was a transport aircraft bound for Schonefeld that for whatever reason went right past it until discovering its mistake.
The Russians were very anxious that it was understood that the incident was completely unintentional, as against many others, in the corridors and in the zone, that were very intentional!
