I know I’m running a little long (again) but in my defense, this is in color, and I think better quality than usual.
“Survival”. The YouTube notes say this dates to the 1980s, but the opening says 1978. I’m kind of wondering if at least one person on my blogroll saw this when they were serving.
The other thing that makes this interesting to me is that the setting looks more like Europe (or some areas of the US) rather than the general run of “survival at sea” films I see a lot of on the ‘Tube. Not that there’s anything wrong with those, but I’m far more likely to be lost in the woods than to be bailing out of an aircraft at sea.
Bonus video: “Land and Live in the Jungle”. From 1944 and featuring Van Heflin.
