The two pictures i found in the depth of my HD. Cant remember from were i got it. But the one with the stored Mirage and the Phantom i have seen in a book long time ago (before the change in 1989). But dont ask me which book it was.
In the other forum the guys said, that the picture was taken in Shukovski, not in Monino. And one other said, that it could be, that the two planes are only wooden mockups.
Maybe that it was posted to give the west something to worry. Dont know.
Maybe, that the planes were rebuilt from shot down wrecks.
That western technic was in eastern hand i have eyewitness.
During my military time i had an "enemy weapon training" were i had the chance to shoot with M-16, G-3 and FAMAS. I have seen M-60 and Leopard 1 tanks which were used for shooting tests to find weak spots.
Defection of pilots from east germany to west (Danmark) happend 1 time (a Yak-18) and from west to east germany also 1 times (a small prop plane somewhere in the 70th i think).
