Duane found himself trapped in the south peninsula yesterday on the same day his wife was due to give birth in the city.
A plea on social media for advice resulted in a local helicopter charter company helping out – with a healthy baby born later in the afternoon.
He spoke to John about the dramatic turn of events, describing it as a very "Brad and Angelina" event!
