What I can never understand is our inability to learn from obvious outcomes that the past has shown us... If some "test", requirement or license is implemented in regards to our hobby, that will mark the beginning of the end! Those do-gooders will not be happy with just a few standards or requirements...before the complete demise of our hobby they will require various other tests that include flight ability, health, age and so on.... Just look at the FAA and aviation now for the answer before contemplating your utopia. Keep that door closed at all costs IMO.
