John flew three full airshow seasons as Belgian demo pilot and this job brought and a lot of work and sacrifices. Besides being a demo pilot he also had to fulfil his daily job as a fighter pilot. Over those three years John flew dozens of demo’s and went from the south of France to Greece and from England to Poland and so on.
