A roughly 45-minute vintage US military instructional film that gives a comprehensive overview of celestial navigation, covering sextant use and the theory behind lines of position.
HN 推荐的原因： HN points to it as an unusually clear teaching film on how celestial navigation works, and as an example of how good old military training material is.
“I love these military training movies, they're so good at teaching complex concepts.” 阅读 HN 讨论 ↗
