Quite recently a new Shopping Center near Darmstadt, Germany called "Loop 5" opened its doors. There are 2 preserved aircraft, a Mig-21 and a TS-11 Iskra. The centre is located at Weiterstadt, about 15 kms south of Frankfurt Airport, just off the A5 motorway.
The Mig-21 PFM, assumingly ex 6910 of the Polish AF, can be found right below the roof windows. Unfortunately, it wears a fantasy paint scheme now.
Iskra 1621 is displayed in its original Polish AF colours inside “Dielmann” shoe shop. Not the best conditions to take a decent picture here.
