I too have known a few Naval Aviators who couldn't fly, some COs.

I assume you're engaging in a bit of hyperbole. They must have been
able to put an airplane on a carrier deck, or they woudn't have had a
pair of gold wings.

They must have been able to stay alive long enough to get to be a CO.

Just how bad were they?

It's been half a century since I flew in the marines, but I don't
recall any NAs or enlisted pilots (I knew two) who couldn't fly
pretty well.
