Some of you suggested it a long time ago. I laughed it off as unreasonable. But then I found this:It's a decent RC sub with a watertight enclosure for a camera. But of course, the camera is removable. That means in theory it could be used to record video flybys of the habitat from outside, or with the addition of a compressed air canister (and a weight to counteract it's buoyancy) little Megafucker could go on submarine missions.
Unfortunately it costs about $700. But hey, maybe someday.
