Taming Liquid Hydrogen
Added 2019-12-10 18:44:07 +0000 UTCAnother free NASA historical book I've been reading through, I wish I'd read it before making yesterdays video because there's a fun anecdote in there involving hitting a balloon tank with a sledgehammer. Also the reason why Pratt And Whitney got to develop the RL-10 engine despite having no rocket engine experience before.
