I went over to Errol one day with Tommy Blyth in Tiger Moth G-ANNG to learn how to do "runway landings" (Perth was all grass in 1958). Tommy briefed me that we would be doing touch-and-go landings and that he wanted me to keep the tail in the air to save wear on the tail skid. This I did but when I opened the throttle after the first landing, the runway disappeared sideways and Tommy had to take control rather rapidly. That was when I learned about swing on take-off! I never did it again - not even on the Piston Provost.
