Dear Owain,
You are simply adding confusion by trying to conflate the two events
It is easy to be confused when theory of systems are not very familiar. Many pilots and engineers would be happy, feel much more comfortable, and work safer by increasing mutual transdiscipliniraty despite it needs, once again, a sharper selection, and still more time for formation.
Theory of systems and pluridisciplinarity help in all domains of modern life. Isn't ?
