The video actually came from the Dick Smith Explorer first television show which went to air on Channel 7 in March 1980. This show was called, “The Early Years” basically following in the footsteps of Captain Arthur Phillip and the settlement of Sydney. I followed with another show called, “In the Footsteps of Sturt” about a year later. Unfortunately these are no longer available as they were on old 2” tapes. One day when I am very, very old (not long!) I might flog them off to cable TV and we will run some of them. There are some fantastic bits-and-pieces.
By the way, the main point of putting the segment on was that at that date helicopters had to operate as if they were fixed wing aircraft. In the case of Sydney Airport, you actually had to depart or approach from the active runway. Of course, we managed to change that a few years later but not without great resistance.
