Very interesting. I had no idea they had para-belles back then. I am going to add the web site link to my history collection. Thank-you dearly for the link!
In the article, it talks about them undergoing 11-wk survival training in Canada (assuming the area around Jarvis Lake / Hinton). It may have been someone like Tom Roycroft (Mors Kochanski's mentor and inventor of the Roycroft pack frame) who taught them bush skills. I'm not sure about the timeline but Roycroft started out as a trainer for the Canadian airforce. EDIT: The video says he had been a DND Survival School instructor for 18 years when Mors met him so that means since the late 40's/early '50s.
Who is Tom Roycroft? My connections are to the nurses slim - I had one great-grandfather GSW wounded in WW1 and nursed back to health circa 1915. And one of my uncles served at CFB Edmonton during the '50s (Korean War) as an aero-engine tech.
