The first machine built by Mr Williams was constructed by Geoff in the family home in Stewart Street, Dunedin, while he was still at school, but it proved on a number of occasions to be too much of a handful and thus he moved on to the Aeroplane. The biplane was badly damaged in an argument with a hedge before any significant flights had been undertaken, was flown from an old wartime emergency airstrip situated on a farm owned by the Neil family on the Otago Peninsula, New Zealand.
