Great - you were one of the few using commonsense -as there were no separate helicopter rules in 1967 for operations at airports.
In 1979 a pilot could sit for 20 minutes at the Darling Harbor pad waiting for a clearance from Sydney Approach to depart to the west because the regs required VFR aircraft in primary control zones to be separated as if the pilots were blind!
It was only after my best selling book. "Two Years in the Aviation Hall of Doom" that this was fixed after fierce resistance to change.
