It's a good point, I'd be very surprised if there wasn't a single Baltarian ship captain. Especially given that Captain last week wanting to know what he made of the Galactica situation.

EXACTLY. Watch your own damn show, people!

It's interesting that you view this as his selfless act - you could really be right. I can't quite bring myself to believe he did really want to go on a probably suicide mission though, since this is Baltar we're talking about

Thing is? He knows it's not a suicide mission. At least, not for him. Because Chip!Six has never lied to him. Ever. By going, he commits a "selfless" act and saves the cheerleader child, and by staying, he commits a selfless act and dooms them all. Classic Gauis Baltar!
