Makes sense to me. Designing such a jet pack would be a very
interesting engineering exercise. It needs to be very agile, but still
as small and quiet as possible. It doesn't need to use actual jets or
rockets, because it's in an atmosphere; probably it would use propellers
of some kind (though those tend to be noisy). And as for power, it
needs to reliably last one quarter of the game, but not necessarily more
than that.

The cool thing about space colonies is that you get to live, work, sleep
etc. under a full 1G, or whatever level we determine is best for health
(of children especially). And yet, you can play at any other G level
you want, including zero-G, just by taking the tram (or whatever) to
that part of the habitat. Try *that* on your Mars colony, Elon! :)
