That seems like what would happen if no controls were on board, or if no cable were attached - but who in their right mind would get into that thing if it wasn't operable to the extent needed to descend and ascend safely? Or have small buoys to launch to signal with?

One way to avoid bringing extra stuff into the house is to simply not go out. My shopping list is growing, but nothing has completely run out (dog food, for example). Tomorrow.
