Working for a previous employer, I was doing a good deal of helicopter supported field work in the Brooks Range foothills. We did some of our safety training through an Anchorage outfit called
Learn to Return. LTR does a lot of training for oil and mining companies, and various state and federal agencies. They have also done some contract training for the military. Generally a well regarded outfit.
We did their 16 hour
Aviation Land and Water Survival training. We also did their bear safety class (including shotgun training). Both were excellent.
(All the usual disclaimers....I own no stock in LTR nor do I have any financial interest....yada...yada...yada.)
