There's been a really good doco running here in Oz re the rivarly between the USSRs Korolev & the USAs von Braun. Fascinating stuff for us baby boomers that grew up in that period of history.
That Saturn 5 rocket engine must really have been somethin'! One of these years I'm gonna have to do Oshkosh & see if I can't link it in with a visit to a test firing of a half decent sized rocket motor.
