Going back a few years both in the RAAF and civilian flying schools, it was considered good airmanship (Oops sorry! NTS or Non Technical Skills) to employ two wing walkers when Tiger Moths were taxying close to people or buildings. In other words someone on each wing tip to help guide the machine. With known crook brakes and a tail wheel on Australian registered Tiger Moths, it would be a good flight safety precaution I would have thought to employ someone to do the job. Offer them a free ride at the end of the day or better still pay them..
