Sorry to ask such a similar question as the last one, but I already marked that one as answered. My friend who works at the Endeavour exhibit in LA found this diagram left on the ground after a gentleman from Rocketdyne came in to look at their testbed SSME on display.
He insists that it does not exist in the public domain due to it being labeled Aerojet Rocketdyne proprietary. I'm pretty sure it's got to, as at least the engines are owned by NASA (even if the design isn't (?)). If is it not in the public domain, how and why? If so, where can I find it?
Just for clarification, I'm all but sure this is simply a color version of the same diagram in the linked photo.
