There is no connection between the between the skills needed to fly 
fighter aircraft and diving a rebreather. If you own a rebreather, then 
you must be able to dissassemble the unit, reassemble it, repair it, 
understand it and dive it. If your desire is to recreationally 
dive a unit and not own one then you need to rent a Fieno or the RBC 
Odessey which are devices that will extend your gas supply for longer 
dives (45 minutes for Fieno; whatever for the RBC) and not require the 
level of competency needed for more complex rebreathers such as closed 
circuit units. But to suggest that a unit need lock up if you haven't 
used it in a period of time or lock up until it is returned to the 
manufacturer for periodic refurbishing is totally ludicrous. It means 
that you really don't own the unit (I'm talking the CisLunar) for the $15K 
you've spent for it and the $3K for training. For me, that is totally 
unacceptable. Even life support equipment in hospitals is not done in this 
fashion. In North Carolina, if your car doesn't pass required annual 
inspection, it doesn't lock up on you. You just don't get the sticker for your 
windshield. You can still drive the car but risk a ticket or mechanical 
failure. If your scuba tank doesn't have a current hydro sticker it 
doesn't lock up and become unusable. Or your regulator, or your dive 
computer. Rebreathers are essentially no different. Perhaps requiring that a 
potential rebreather owner know the mechanical and electronic workings of 
the unit they intend to purchase and demonstrate that competency before 
they purchase ought to be a requirement. Perhaps if you can't take it apart 
and put it back together in working order, make a malfunction diagnosis and 
fix the problem with spare parts or whatever, you shouldn't be allowed to 
buy the rebreather. I'm not even sure that would work. You aren't 
required to have that kind of knowledge for driving a car, flying a plane 
or running a locomotive. About the best that you can do is to offer a 
good unit, offer competent training and if an individual passes the 
training, he gets the unit. The end. What happens after that is the 
owner's business. Let Darwinian evolution work. Because rebreathers are 
new technology in recreational diving does not mean that Draconian 
measures need be installed to protect people from themselves. Become 
educated about rebreathers and use one regularly and most of your fears 
will go away and those that remain can be easily dealt with. Rod
