Can anyone confirm this story that I became aware of in my Argosy days? I believe it is from 1965, when the Bundestag held a meeting in West Berlin, something to which the Soviet Union took great objection, claiming that the city was not part of the Federal Republic. All manner of hindrances to Berlin access were initiated and, amongst other things, special probe flights using the Argosy were tasked. These would often see a MIG on the wingtip at some point. On one occasion, it was said, a captain slowed to airdrop speed and opened the rear doors, at which point the accompanying MIG had to give up as an incipient stall threatened. I'd like to think it was true.
