Re: Well, we're not designed to fly . . .
. . . that is, to fly well. One may still be catapulted -- but the landing might take some practice.
We're also poorly equipped for swimming, but then I've handled the transitions for both flight and swimming with little difficulty. High seas would give me some trouble, as would being airborne and suddenly deprived of an airfoil, but as long as we hang on, we're doing fine.
