t211, apologies for not mentioning Dan-Air's 748's and 146's. Berlin was a gold mine for Dan-Air and other non-German airlines (West German airlines, including Lufthansa, were forbidden from entering the Berlin corridors); income in DM's and most costs in £'s. Though as the pound continued to sink each visit meant the beer cost more in £'s, though its DM price stayed exactly the same.
JW411, the events that you describe were no doubt in the forefront of BARTCC and BASF minds when, unannounced and off frequency, a Soviet transport a/c entered the Berlin Zone from the East. Continuous avoiding action for Tegel and Tempelhof traffic was necessary as it meandered erratically through the zone. Was this yet another Soviet provocation? Was there still more to come? Just as suddenly as it had appeared it exited the zone and disappeared into East German airspace. While the turmoil it had created subsided and normal routine was re-established, a phone call came into BASF. It was from the Soviet Airforce HQ in East Germany. Far from being threatening and bombastic, the tone was apologetic and reassuring. Their ATC had lost R/T contact with this nomad and they hoped it had not created too much trouble. They promised that severe disciplinary action would be taken against all those that had failed in their duty at their end. It was one thing to beat up the Reichstag when so ordered, quite another to make waves of one's own accord!
