My very first encounter with an operational MiG! This was at a time when East Germany was still staunchly pro-Soviet, although the first cracks had started to appear. This resulted in my invitation to a very low-key open day at Peenemunde where Jagdgeschwader 9 was based at the former Nazi rocket testing ground where the V1 and V2 were developed.
The L-39V was a little-known version dedicated to target towing. Although all East German L-39's used to be based at Bautzen in the south of the country, Peenemünde (in the north) mostly had some L-39V's on strength for use at the nearby ranges over the Baltic Sea.
It was not difficult, apparently, to obtain one of the German navy's retired Atlantics, and this signals intelligence machine was added to an obscure small collection here at Peenemünde airfield. Note that this location is not the rocket test base site.
