Firstly: yes, this of course is a propaganda movie.With this out of the way, it was an interesting watch. In a mix of air force pseudo-documentary and private life scenes, you get impressions worth some thoughts from back then and there.In kind of a nutshell, many contents are compressed. You have the American bomb (left over from WW2) that kills one protagonist, a visiting Soviet general (who was also in the Spanish civil war), a brief sketch of relations with Poland, detailed discussion of pilot's illusions, and much more. There are flight fitness tests which remind me of Space Cowboys, multiple jet planes (somehow Starfighter F-104 lookalikes) in the air, one crash with pilot ejection, alas, to too shallow waters.All in all, an interesting viewing. You can watch this on YouTube, stitched together from seven parts. I found it worth the while.
