Some years before there even was an IGS (and for several years after as well) there was the CC NDB approach to Runway 13...via Stonecutters and RW NDB's
An interesting ride across the harbour...especially at night, in the heavy rain...
Afterwords, time to retire to the bar and ....'make mine a double'.
Hmmm, come to think of it, 'reverse thrust' was even better'.
Sadly, the younger guys will never know the pleasure.
