Every recreational aircraft is mandated to display a prominent warning about the lack of official oversight both in design and maintenance, and that people fly in these aircraft at their own risk. Aviation has been officially recognised in the law courts as a potentially dangerous activity. Just like...Umm, base jumping or snake handling. No person is innocently flown in such aircraft, they are all advised to make their own judgement. I think, regardless of the circumstance, for example flight training, that they still have to make their own judgement . Warnings are not placed in our aircraft as a simple sop to conventions. Some of the faux concern and hand wringing comments are out of order.
