I just gotta say I disagree with this whole idea on a number of levels.
I've always seen the adding of Valentina as a sorta tokenizing measure. An unnecessary one at that, seeing as Kerbals were mainly meant to be asexual.
Also, I fail to see the equality in naming female perhaps after famous historical femaled in the field while the male kerbals have no such thing with their names.
I didn't see the point of adding a 4th kerbal when Valentina was added (regardless of sex) and I see no point in adding 2 more. We might as well just remove hiring Kerbals at all if you are gonna stack the initial crew so much.
As for rhyming, Val Sal and Hel don't rhyme.
Also with your weird post about the SWA 1380 pilots that's completely off topic, I'd say that comparing her to sully is hardly a fair comparison. She followed a pretty basic training procedure that pilots perform many times a year. Sully had to basically write the training procedure in his head in a few minutes. Kinda a big disconnect. But as I said, that's off topic and I'm not quite sure why it's in this post.
