SASless - I hear you, but AJ had a lot of time in the province and could be expected to know where those mountains were, with or without navigation systems. We ought to get the public away from this idea that just because there's a machine in the cockpit you have to obey it. How many times have I had surveyors in the back "navigating" with a GPS where good map reading has told me they were way out.
it would be a good argument with a counsel, that's for sure.
As for freelancers, they don't have the "master and servant" protection that an employee would have, such as it is in modern times. Public liability insurance would be a good step, as would making yourself into a limited company.
