Nimbus, et al - there is a difference between LAW and INTELLIGENCE.
If the airspace is NOT controlled then you can do what you like in it - by definition.
It may not be a very good idea, indeed it may be bloody stupid, but what is legal and what you do may be completely different.
It's a bit like flying a Saratoga on a hazy, pitch dark night across water to an island off the coast somewhere - without an instrument rating (or sufficient instrument training).
It's not illegal - but it proved to be deadly for some....it all comes down to airmanship.
