I'm sure RM ban them from flights. They're not banned from flights.

I suspect RM ban them like they ban everything else because they don't have the expertise to determine safety without inspection and jump for the lowest common denominator. Understandable but let's not say it's not possible because it is. All sorts of things can be flown, some need more paperwork, some don't.
Unaccompanied they are not allowed. RM do not set avaition rules they just follow them, it's as simple as that. If I had the inclination I could search the link that proves the avaition rules but it's been done so many times....
