Thanks. I don't know when this was taken, but the video is new on http://www.fabulousfulcrums.de
(English/German - very well worth a visit.) and weather isn't exactly good, so maybe it was taken in September or early October this year.
The only German air wing with MIGs is stationed at Laage AFB
, close to Rostock and the Baltic Sea.
I do not think they were practicing for a display. It seems the video was taken by a former member of the air wing, and when he visits the AFB
, pilots make a low fly-by to honor him.
