Alright, so recently in TWE, I put out that Mobian sized bats couldn't fly, but could glide short distances due to their wings. I got to wondering if it was plausible for a human shaped bat to actually fly with either backwings or arm wings (like real bats) could actually fly.
Any responses or thoughts? This question's gonna be biting me all day.
EDIT: I'm trying to go for the REALISTIC option here. It's a rule of my setting that totally mundane people can't break the laws of physics by themselves.
