When on B Sqn at BD one of my ancilliary jobs was to train any "Kerosine Kids" going on to BBMF to land the Harvard. Started them in the front seat and then moved them onto the rear one. I know from experience that that is trickier that a Hurricane. After a season on the Hurri they would move onto the baby Spit and, subsequently, onto the Mk19. I was lucky enough to train on the Harvard, fly it extensively at BD and then fly with the Harvard Formtion Team as a civvy. Over 500 hrs.
