Von Braun's Lunar Trajectory

In my post about Lester Del Rey’s 1956 sci-fi thriller Mission to the Moon, I criticized Del Rey’s cis-lunar flight orbital mechanics. Del Rey had his moon missions leaving from a polar orbit around the earth. This struck me as very odd - all real lunar and interplanetary missions have left from a more-or-less equatorial orbit, or maybe even fly directly into an interplanetary orbit. I thought Del Rey had completely misunderstood orbital mechanics, or had mis-read von Braun.

I was wrong.

I’ve been reading science fiction for a long time, since maybe second grade, circa 1968. I believe that the first scifi book I read was Lester Del Rey’s Mission to the Moon.
