There are always air currents on space ships.

But simply not enough. If you are part of a frisbee competition held inside, a coliseum for instance, there simply aren't enough air currents to compete if you are relying on them. Expensive, very light, very aerodynamic frisbees are used. They use what little current is available, and there is no danger of dumping a Cleveland in the English Channel, the Nantucket Sound or any ocean or forest.
But I assure you, getting a 175 gm frisbee to perform inside a coliseum is a no go, even for me, and I'm good. Now inside, playing frisbee football it's okay. Gooooo looong ...
Hi cthia, glad you had a great vacation
I'm not sure how future ship builders will cram environmental controls into a can in space but if it is anything like the ships I've sailed in not only will it be turbulent and noisy but it won't be enough Spacers will shove things into the vents to change the flow to their satisfaction much to the chagrin of the occupants in the next work center over. They will put there favorite beverages in the ducting to cool them down and some will invariably roll away creating odd eddies in the air flow and that mysterious clunking noise haunting the ship for ages. Then an industrious spacer actually gets around to fixing the impeller somewhere and finds it lodge in a corner rewarding them for their diligence ( at the other end of the ship four years later.)
