Piers did my Flight Instructors rating and I learnt more in those few weeks than I have learned. How he manages to maintain such enthusiasm after so long in the job is beyond human comprehension. I have never met a more knowledgeable, enthusiastic and committed person in my life. Anyone who is fortunate to get some time with him will echo this and other posts. Hats off to the Smerd and I only wish there were more like him
