The notion of flying airships through passes in the Alaska range, as
shown in one of the frames, strikes me as out of touch with reality.
Mountain passes here are dangerous and unpredictable moment to moment
even for high power to volume prop aircraft.
In the 1960's I worked for a company that evaluated the use of blimps
to transport natural gas from the North Slope of Alaska to the lower
48. Natural gas is lighter than air. This is or will be likely
economically viable, if the danger of flying tons of hazardous stuff
to unchosen locations is ignored. 8^)
