So, I apologize if this has been asked before or if it's an extremely silly question, but I just bought 0.16 the other day so I'm still new to all of this. Basically, how many Kerbalnauts are there/ is there a limit? In my attempts at Mun landing, Spaceplanes, and other shenanigans I've probably had at least 20 of them meet their unfortunate demise, and I'm wondering if there'll ever come a time when I run out of pilots for the space program. Anyone know? Thanks in advance!
