well, the scale here is just copy and pasted from the scale in the lower right-hand corner of the screen shot. i just opened it up in paste and copied it across.
it's roughly 1 km. if she was out a bit, it'd be less than that. that's a workout, no doubt, but it's not insurmountable, for somebody in athletic shape. i bicycled 110 km a few weeks ago, out of the blue.
the kid says he didn't see her leave the water, but what does that mean? are you going to rely on a child's ability to discern characters a km in the distance, over open water? i dunno.
hey, if they find her mutilated corpse, desecrated by a tree branch, snapped at the sternum three ways, the sanctity of her existence irrelevant to the forces of physics, then so be it.
but, if they don't?
if she vanishes without a trace?
that's a doable swim. certainly. does naya swim?
