As opposed to the York operation?
I know which one I'd rather not be at.
I think times and operational methodologies have changed at several DZs. How much any of them pay I don't know, but could be dependant on the capacity of the "employment" such as pilot only or chief pilot or what.
Just an idea for thought.
