Here are couple fantastic pictures from Mikkelin Ilmailuyhdistys (MIY). Translated loosely to Mikkeli Aviation Society. These pics have originated from album of Pentti Pohjanvirta via Sakari Silvennoinen.
I think that these are truly wonderful for many reasons. One of being that they have not been published before this, at least to my knowledge. There is similar (but different) set of pictures of same time period at Mikkeli Airport history pages, but I cannot find link of that as the pages are currently offline. Also, there is not so many building pictures of classic sailplanes in internet, so these are rarities.
Pictures show building of PIK-5b (OH-PAV) and couple flying pictures of PIK-7 Harakka II (H-47 / n.5). You can find new pictures of same planes at iwaru.fi/galleries.html
If you have further information of person / planes in pictures pls. contact us, tuootal (at) iwaru.fi, I will update captions accordingly.
Also, if you have more historical pictures of PIK-range of planes pls. send them to us, we will publish them.
