While I'm not entirely positive, I think those suckers fly via large eagle-like wings. I could throw a saddle on there and ride one of those things around town, or even on lengthy expeditions to other parts of the world, like Mexico for example. I bet chimeras eat Mexicans. If they do, they'd be doing us all a favor I think.
P.S. I actually love all Mexicans. I love them like I love my pets, which basically means that if they died I'd go, "Awwww. That's too bad". I'm a good person I swear.
