Came across this forum post from a Google search after uploading a video to YouTube from my late grandfather’s cine and audio collection that I have been working my way through and digitising. 

Stan Kocyan was Polish and in their army for WWII. He originally wanted to join the Polish air force but apparently his mother would not allow him so he joined a tank regiment instead. After the war he moved to England and because of his original love of flying he became involved with flying clubs when he could. He also had a passion for photography and cinematography hence the following video he created featuring an unknown pilot and musician and the 302 Pirat glider of the Polish AFA Gliding Club.

Hopefully of interest to some.
