They use compressed air to drive all their tools in the shop.
Sure - but to get air from their shop compressor into an O2 bottle would
require some real ingenuity. Anyone smart enough to do that would be smart
enough not to do it, I should think!

I'm wondering - maybe the FBO didn't have O2 facilities, and some gopher went
out to a local diving supplies shop, and together they managed to jury-rig the
fittings . . .- Hide quoted text -

The fittings for "Transfilling" from a larger tank are readily
available.

Even the larger tanks are thread indexed. You have to work hard
to screw it up. The problem is that dive shops have rigs that mix
gases. They also have devices (and most divers diving mixes have
them as well) to analyze what's in the resultant tank before using it.
