U.S. Navy 30 min 1967 documentary on Antarctic & possible clues

As of April 8, 2016, today, I only found this newsreel from 1967 made by the U.S. Navy. I'll review it in coming days with an ear and eye trained on anomalies consistent with our suspicion that Antarctica is a rim that's 60,000 miles in diamter-- not "an island at the bottom of the world" that is 15,000 miles around. Other paths I'm taking include personal video diaries of Antarctic workers and amateur vlogs of flights to and from various research stations. In these, I'll be listening and watching for any indication of trips between research stations to compare time and distance in reality vs. what is consistent with either flat or spherical earth. I'll watch for those infamous Inspection Tours-- of which none seem to have been conducted in many years-- possibly 10 years. Anyway, I'll be enjoying the following Navy production over coming hours and days and invite you to join me over popcorn as I continue my virtual circumnavigation of Antarctica.  Trump made a very fast and inexplicable reference to Antarctica several months ago. I wish I had noted that here when it happened. Now I'll have to look for it.
