The Battle of Chernobyl

If you haven't seen this documentary, you should.  I think it's the most frightening thing I've ever seen, but the scale of the heroism displayed by the ordinary people in it is amazing.  Though they did not know really what they were going into -- they were lied to, but even the people telling them the lies had no idea how bad it really was -- they probably saved thousands, maybe even millions of people.  The fact that to this day they have never really gotten the recognition they deserve is tragic.
