Mount Saint Helens eruption - story of Harry Truman and David Johnston with eng. subtitles

One of the numerous interviews done with Harry Truman on April 18, 1980, month before he died and a fan made animation of what probably happened on that fateful day when Mount Saint Helens erupted.
Edit 5th May 2019: As I learnt from the comments, the author of the animation which starts around 5:23 is a guy called Deviantart King of 97. Check his channel here, he has some videos about Mt. St. Helens too: / channel
