But then I realised you could carry a COaxial Resealing Kit to manually seal this off . That would work. Or maybe a Big UNiversal Gasket could be used. Hmm. Perhaps I should patent this idea quickly before someone else comes up with it.

We ran a similar exercise here for Armadillo's life support system.
We concluded that they didn't need one. The flight is so short, and
the cabin so large, that CO2 levels won't rise to uncomfortable levels
during the flight even if they don't scrub the air. We also
determined that dumping the air overboard and replenishing it from on
board tanks was simpler than scrubbing it, since they're going to
bring the tanks along anyway, for redundancy.

Our current thinking is to carry an air bottle, and intentionally let the cabin leak a bit to force some air circulation, dehumidification, and cooling. There will also be a hand-operated valve to force it to leak more if you want to clear the air up any.
